L’erosione del suolo può essere definita come la progressiva rimozione dalla superficie di strati di terreno, attraverso il distacco e trasporto di singole
particelle a opera di vari agenti, sia naturali che antropici. Questo fenomeno
di asportazione del suolo può causare danni significativi al patrimonio archeologico esposto o ancora sepolto. Al fine di proporre buone pratiche di
valutazione del rischio dei siti archeologici, il progetto RESEARCH (REmote
Sensing techniques for ARCHaeology ), sulla base di un metodo innovativo,
ha definito un articolato flusso di lavoro in grado di elaborare in maniera
integrata dati archeologici e geologico/ambientali per produrre, attraverso
un software di tipo Open source (QGIS), una più dettaglia mappatura del
rischio di erosione del suolo sul patrimonio archeologico.
Il presente metodo è stato verificato su un’area campione, all’interno del

sito archeologico di Falerii Novi (Viterbo, IT), la cui area urbana, delimitata
da un circuito murario in blocchi di tufo, conserva una complessa stratigrafia archeologica. Il sito, nonostante sia stato sottoposto a vincolo, è attualmente utilizzato a scopo agricolo, con conseguente incremento di gravi
fenomeni erosivi, che comportano un aumento del rischio per la conservazione del deposito archeologico.
La presenza di strutture sepolte nell’area è stata confermata e localizzata
attraverso un’indagine magnetometrica effettuata alla fine degli anni ’90
e recentemente riconfermata da una completa mappatura effettuata con
strumentazione georadar, i cui risultati hanno altresì consentito di stabilire lo spessore della coltre di suolo che separa il piano di campagna dalle
singole strutture sepolte e dalle relative stratigrafie archeologiche più superficiali.
Per la valutazione dell’erosione del suolo e dei conseguenti accumuli sono
state eseguite una serie di simulazioni (tramite dei modelli open source,
quali RUSLE 3D, SIMWE e USPED) che, interpolando dati ambientali e del
suolo, hanno generato delle mappe di erosione del suolo per la valutazione
del quantitativo di materiale asportato e deposto nell’area di studio.
I dati prodotti da questi due differenti flussi di lavoro sono stati poi elaborati in forma automatizzata all’interno della Piattaforma RESEARCH, sviluppata in ambiente QGIS. Ciò ha consentito di generare mappe di minaccia
dell’erosione del suolo e mappe di vulnerabilità archeologica, che successivamente combinate fra loro hanno prodotto delle specifiche mappe del
rischio.
Tali cartografie costituiscono un utile strumento per il monitoraggio di aree
di grande estensione e possono essere utilizzate da enti e istituzioni preposti alla tutela e alla conservazione del patrimonio archeologico, per la
pianificazione di interventi sul lungo periodo.
HUMAN RESPONSE TO LATE HOLOCENE CLIMATE CHANGE IN
NORTHERN ITALY: INTEGRATION OF GEOMORPHOLOGICAL AND
ARCHAEOLOGICAL DATA THROUGH A FLOS-BASED WORKFLOW

H2020-MSCA-IF-2019. Brandolini does research in landscape archaeology, geospatial
analysis and fluvial geomorphology. Dr. Brandolini’s PhD was focused on interdisciplinary approaches in landscape studies, combining geosciences and archaeological
sources with FOSS GIS software products.
Francesco Carrer

https://www.researchgate.net/profile/Francesco_Carrer
Francesco Carrer’s main research interests are in landscape archaeology and ethnoarchaeology, mountain archaeology, spatial analysis and computer modelling. Dr.
Carrer is specifically interested in seasonal pastoralism, from an ethnographic and an
archaeological perspective, and in the development of GIS applications for analysing
long-term socio-ecological dynamics.
The transition from Roman into Medieval Period represented a crucial moment for the reorganisation of human settlement strategies in the Po Valley, mainly due to climatic changes and socio-political factors. Following a
FLOS-based interdisciplinary approach, this research combines geopedological data and archaeological sources to assess the role of alluvial geomorphology for Late-Holocene settlement strategies (fig. 1).
In this research three different FOSS applications have been employed:
QGIS, GRASS GIS and R through Rstudio. Point Pattern Analysis (PPA) (Bevan et al. 2013) was employed to provide a solid statistical assessment of
human interaction with alluvial environments. Variability in Roman and
Medieval settlement patterns is analysed against two related proxies for
alluvial geomorphology and agricultural suitability: flood hazard and soil
20

texture. Continuity between Roman and Medieval sites, which might have
influenced the average relationship of the latter with the two environmental variables, has also been quantitatively assessed through Inhomogeneous cross-K function.
This study investigates how alluvial geomorphology and agricultural suitability influenced settlement patterns in the Roman and Medieval period, and
whether pre-existing Roman occupation attracted Medieval sites. The easiest way to address the former was by assessing whether a selected inhomogeneous model described the spatial variability of a point process more
accurately than a stationary model. Two “environmental” spatial covariates
were produced for this purpose, MTI and SOIL. The third covariate, the distance from via Aemilia (VAE), served as a“socio-cultural” covariate (Fig. 2).
Point Pattern Analysis (PPA) for Roman and Medieval sites were performed
in R using the package ‘spatstat’ (Baddeley, Rubak, and Turner 2015) and
GRASS maps were managed through ‘rgrass7’(Fig. 3). PPA suggests that Roman site distribution in the area has no correlation with flood hazard (MTI),
but shows a weak inverse correlation with soil texture (SOIL). An inverse
correlation with MTI and a direct correlation with Soil have been identified
for Medieval sites. This suggests that different land-use techniques enabled
the Romans to exploit large areas of flood-prone areas successfully. On the
other hand, alluvial geomorphology highly influenced settlement strategies
during the Early Medieval period (Brandolini and Carrer 2020).
To assess the independence of the two-point processes (Medieval and Roman settlement patterns), second-order properties were investigated using
the inhomogeneous cross-K function that was calculated from the sites, as
well as for 999 Monte-Carlo simulated bivariate point patterns. The Cross-K
function highlighted significant proximity of Medieval sites to Roman sites
for short distances, up to 1.2 Km (Fig. 4). This implies that even considering
the different responses to alluvial geomorphological conditions in Roman
and Medieval times, within a 1.2 Km radius, the Medieval sites are closer to
Roman sites than expected.
To conclude, this project represents a useful example of how the integration of FLOS tools is extremely effective and enables a wide range of applications to investigate past landscape dynamics on different scales.

UN WORKFLOW OPEN SOURCE PER L’ELABORAZIONE DELLE
IMMAGINI TERMICHE ACQUISITE DA DRONE
Gabriele Ciccone
cicconegabriele@gmail.com
https://uniroma2.academia.edu/GabrieleCiccone
Dottorando del corso di Storia e Scienze filosofico-sociali dell’Università di Roma Tor
Vergata e laureato in Archeologia medievale, Gabriele Ciccone si è specializzato in tecnologie applicate conseguendo il Master in Tecnologie Open Source per i Beni Culturali
presso il Centro di Geotecnologie dell’università di Siena. Ha partecipato a numerose
campagne di scavo e di prospezione geofisica in Toscana, Sicilia e in Messico Ha svolto stage presso il VHLAB-CNR e ha lavorato presso la Noho Ltd. di Dublino, dove si è
perfezionato come modellatore 3D per la fruizione e valorizzazione dei beni culturali.
Socio dell’associazione Una Quantum Inc, è docente per i corsi di Modellazione 3D per
i BB.CC. con Blender.
Nell’ambito del progetto di dottorato “Flying off-site: nuove metodologie di
indagine per l’analisi dei paesaggi storici” (XXXV ciclo, Dottorato in Storia e
Scienze filosofiche-sociali, Università Tor Vergata), parte della ricerca è stata dedicata all’individuazione di un workflow efficiente per l’elaborazione di
rilievi 3D e ortofoto ricavati dai sensori termici.
Nella prima fase sono state programmate riprese termiche della stessa
area con voli effettuati in diversi momenti della giornata, al fine di valutare
le variazioni termiche dovute ai differenti orari di ripresa. In questa fase, a
causa della bassa risoluzione delle immagini termiche, sono stati effettuati
voli aventi strisciate sovrapposte con un overlap di 90% tra gli scatti, lateralmente e longitudinalmente. La seconda fase, dedicata all’elaborazione delle immagini, è stata svolta con differenti software sia proprietari che open
source, al fine di valutarne le potenzialità in termini di precisione del dato
e di velocità dell’elaborazione: è apparso subito evidente come l’orario di
ripresa determinasse la buona riuscita o meno della fase di allineamento
delle immagini, in tutti i software fotogrammetrici proprietari e open source
testati.
Le elaborazioni hanno evidenziato una situazione differente tra i set di immagini scattate in condizioni di buona luminosità, rispetto ai set ricavati dal-
24
ArcheoFOSS | 2020
le riprese effettuate dopo il tramonto e prima dell’alba. Se nel primo caso,
infatti, tutti i software hanno correttamente individuato i punti in comune
tra le immagini in fase di allineamento, riuscendo ad elaborare sia le ricostruzioni 3D che le successive ortofoto, nel secondo la scarsa luminosità
delle immagini non ne ha permesso un corretto allineamento, impedendo l’avanzamento delle elaborazioni con tutti i software proprietari e open
source testati.
In linea con la letteratura scientifica in materia di fotografia termica al di
fuori del mondo archeologico, è stato elaborato un workflow che permettesse di unire le immagini RGB e IR (termiche), in formato JPG, in singole
immagini in quattro bande ( R, G, B, IR) in formato TIFF, al fine di riuscire ad
elaborare le immagini TIFF con i software di fotogrammetria per la ricostruzione del rilievo 3D e la successiva elaborazione dell’ortofoto, da cui infine
estrarre la banda relativa all’immagine termica. Inizialmente, con gli esempi
ricavati da altri ambiti di applicazione delle immagini termiche, il workflow
è stato elaborato facendo ricorso a software proprietari: è stato utilizzato
Matlab (software chiuso ma distribuito gratuitamente per la ricerca universitaria) per le fasi di conversione in grayscale e ridimensionamento delle
immagini IR (da 640x480 a 3840x2880), per il taglio delle immagini RGB
(da 4056x3040 a 3840x2880), e infine per l’unione nelle singole immagini
TIFF a 4 bande; in seguito le immagini sono state processate con Metashape, dalla ricostruzione 3D fino all’estrazione della singola ortofoto termica.
Raggiunto l’obiettivo, il passaggio successivo è consistito nell’elaborare un
medesimo processo di lavoro adoperando soltanto software open source,
sia per valutare un’effettiva possibilità di workflow esclusivamente open,
che per verificare pregi e difetti rispetto ai software proprietari. Sono stati
testati differenti software sostitutivi di Matlab (GNU Octave, Scilab, SageMath, R) arrivando infine a preferire Octave in quanto il più simile a livello di sintassi; ciò ha permesso di non dover rielaborare né stravolgere le
funzioni già utilizzate per Matlab. Successivamente è stato sperimentato
il software OpenDroneMap (attraverso l’interfaccia WebODM), sia tramite
i nodi di calcolo interni che con quelli di MicMac, per arrivare all’elaborazione dell’ortofoto. Tuttavia, per l’estrazione dell’ortofoto IR, non essendoci
tale funzione in ODM, sono state testate differenti possibilità, tra le quali le
migliori sono risultate essere QGis o il freeware Multispec.

Renata Ago former Full Professor, now Honorary Professor at Sapienza University of
Rome where she taught Early modern history. She has been fellow or visiting professor
in several institutions and member of the editorial board of different academic journals. In 2009-2014 she was the general scientific coordinator of the European project
“European Network for Baroque Cultural Heritage”. Her scientific interests concern social history in early modern times. She has worked on rural communities and feudality
from the 16th to the 18th centuries, on family and gender history and on the relationship
between social exchanges, economic practices and institutions. Her recent interests regard issues on consumption and material culture.
The aim of this paper is to describe the methodology employed for the
development of a GIS platform capable of analysing urban mobility in early-modern age. In order to increase the dissemination of data, QGIS is the
software used in this research. The use of this tool has allowed not only the
intercommunication between different operating systems (OS), but also the
production of open source data. The research focuses on the case study
of the pathways which took place inside and in the surroundings of the city

walls of Rome in the 18th century. The town in this period appeared with
an urban layout that was the result of a series of important initiatives by
the authorities, especially the popes. As a result of these transformations,
the increase of regular roads and “straight streets” is evident, as well as the
adjustment of town squares and buildings. During the planning of the GIS
project, this urban layout, which for the most part is no longer visible from
modern satellite images, was recreated by using a georeferenced version
of the Nuova Topografia di Roma by Giovanbattista Nolli: a city map that
was published by the geometer in 1748, and which faithfully represents the
urban landscape of eighteenth-century Rome.
Initially, several official itineraries such as papal parades, solemn entrances
of ambassadors or foreign princes were mapped out. These paths were
traced having access to accurate topographical information obtained from
the analysis of booklets published on the occasion of particular events. In
a second time we have mapped the common and ordinary daily movements of men and women, workers and shop masters (fig. 1). The itineraries of these “normal” people show a completely different picture from that
obtained from the examination of the high-codified pathways. In fact, the
reasons for these journeys mostly concern work or social occasions (fig. 2),
such as visits to taverns. In order to collect the topographical information
related to this kind of events, we have used a wide sample of judicial sources (trials and claims of the Tribunale criminale del Governatore) as well
as of requests forwarded to the Presidenza delle Strade. In this phase the
topographic data are less detailed than the previous ones and are mostly
limited to a departure point and an arrival point, and in some cases to intermediate stops.
The vector data collected during the entire project were then queried in
QGIS by spatial analysis aimed at detecting the main routes of urban movement in early-modern period. It emerged that the “new” roads built in the
18th century were rarely used, even in the context of codified pathways
such as processions. In fact, the choice of roads appears to be attributable
to factors in which the comfort of the streets is not the conditio sine qua
non. In conclusion, the project in its entirety highlights the potentialities
to analyse the topographical data obtained from the study of the textual
sources by comparing them with those present in historical cartography
through the GIS platform. Through this approach, it was possible to obtain
a complete overview of the urban movements in 18th century Rome in
relation to the new city building developments that have taken place in the
town (fig. 3). Furthermore, this approach made it possible to query the data

in order to extract information leading to an improved understanding of
the uses of an ancient urban layout of this city.

How far the willingness to achieve specific research goals can drive us into
non-conventional strategies? Every day we have to make important methodological choices about scientific and sensitive data, also making compromises. In this sense, the point is always minding the goal of the research, avoiding the use of specific innovative technologies / methodologies /
software just for fashion and thinking responsibly depending on resources
we spend and data we produce.
32
ArcheoFOSS | 2020
In this sense, BIM (Building Information Modelling) methodology – which
has become a standard and a mandatory solution for AEC industry (Architecture Engineering Construction) – is recently spreading more and
more inside the Cultural Heritage panorama due to its possibilities through
three-dimensional databases, related information, queries as well as integration between different kinds of data and professional figures involved.
However, the adoption of BIM methodology for Cultural Heritage assets
– becoming HBIM (Historic Building Information Modelling) as well as modifying the main workflow (BIM, referring to new constructions is placed at
the beginning of the life-cycle of the building; HBIM should be intended as
the knowledge of the historical building and then it takes place in a specific
life-cycle moment) – is affected by different compromises and issues, especially referred to the software used, mostly designed for AEC industry that
rarely fit with Cultural Heritage domain (e.g Autodesk Revit).
This reasoning brings researchers to run into the accuracy and reliable issue of the commercial BIM solutions towards free / libre and open source
(FOSS / FLOSS) BIM software, especially for Heritage assets, and the utilization of FOSS BIM solutions for Cultural Heritage domain apart from being a
milestone could be also considered a real challenge as well as a watershed.
In fact, an unconventional but fitting and good solution to guarantee Heritage data usability, accessibility, transparency and customizable opportunity could be provided by FOSS BIM software thanks to source code accessibility and modifications possibilities, adapting software to Cultural Heritage
needs and not the opposite.
So, HBIM methodology is changing the way to produce and investigate Cultural Heritage documentation, at the same time FOSS / FLOSS solutions are
changing the general view as well as possibilities of BIM and HBIM methodology, but how does this happen?
FOSS solutions are becoming more and more fundamental and reliable as
far as archaeology and in general Cultural Heritage documentation are concerned: in fact, archaeological domain can rely on open source full operative
system as ArcheOS based on GNU/Linux; regarding 3D modelling, Blender
FOSS software has demonstrated over the years to be as precise as reliable;
at the same time QGIS (Quantum GIS) has proved to be an essential solution for geospatial analyses especially concerning Cultural Heritage assets
as well as the most widely used GIS platform; moreover, the utilization of the
FOSS photogrammetric suite MicMac has grown outrageously, proving itself
equal to others commercial software. Then, FreeCAD FOSS / FLOSS software,
through its possibilities, could be equally important as CAD and BIM / HBIM

solutions , taking part of this FOSS ecosystem.
Despite HBIM methodology has the potential to become a good answer
for building archaeology documentation and analysis, by using ad-hoc and
customized FOSS tools as FreeCAD it could become the proper and fitting
solution overcoming AEC industry limitations of standard BIM software: in
this sense, this project is focus on experimentations, custom modifications
and adaptations of FreeCAD to building archaeology assets as HBIM custom platform for documentation and analyses (adapting custom HBIM
workflows to specific needs), trying to avoid methodological compromises
related to commercial BIM software as well as trying to preserve the original goals of specific research.

The area of the north-east Palatine hill slopes in front of the Colosseum
valley has been the place of a more than 30 years long archaeological research, that brought to light to many archaeological evidences and material remains of ancient buildings and monumental interventions of great
impact inside an environmental, topographic and stratigraphic continuum.
The huge amount of documentation produced has required the development of a data storage and management system dedicated to give a logic and
integrated framework to information but also able to propose new elements
for research development. Since 2001 the whole archaeological record has
been managed by an intra-site GIS for data-retrieving, spatial analysis and
archaeological reconstruction.
During the research this system has been implemented in contents but also
in technology, following the advent of new IT products. In particular we dedicated our attention to the spread and availability of open-source software
and ArcheoFoss: this in the last years, together with the support of a community of professionals and developers, undoubtedly has represented a fundamental pivot of technological development in archaeological practice with
increasing interest and participation.
Our research follows this approach paying great attention to open-data issues and experimenting with entire datasets migration reconstructing the
entire system in Qgis open-source platform. This process has addressed
not only technical problems? , related to the nature of some proprietary
formats, but also, and above all, has generated new reflections on the possibility of renewing methods and techniques for collecting, managing and
analyzing data.
Focusing on the study of the ancient building, the use of image-based-modeling photogrammetry techniques revealed a certain inadequacy of the
exclusively chrono-typological study of the ancient walls. In fact, these approaches, being anchored to two-dimensional projections of the artefact,
inevitably neglect factors related to the three-dimensional environment of
structures.
From these reflections, while we were making a new 3D documentation of
the ancient walls, in this last 2 years we have performed also a new and integrated recording of the structures, having planned a new form format by criteria aimed at the collection of information related to construction methods,
structural expedients, yards dynamics, specific materials selection, quantification of the work in terms of time and number of the workers.
This new file-card format for ancient masonry contexts, for data display, en-

try and editing, was created directly by Qgis. For the contents homogeneity and to facilitate data entry procedures, we have encoded standardized
terminologies; in addition, the detailed metrics information and statistics,
derived from the analysis of the samples of wall facades, are managed by
accessory modules.
All these data are linked to 3D documentation of masonry stratigraphy: in
detailed level for the evaluation of single walls and samples; in a general
framework level for diachronic and typological evaluation of the architectural complexes of the area.
An external connection with the open-source software CloudCompare is
a first attempt to show the graphic quality of the photogrammetric acquisition and to partially overcome the 2.5 dimensional perspective of GIS.
Finally, particular attention was paid to the question of the “philological
transparency” of data considered like the “basement” of archaeological
interpretation. In order to deal with this problem, we have reproduced a
new system for collected data analysis and retrieving: photos, 3D models
acquired from scratch, sections and elevations, hand-made drawings and
all raw data produced during the excavation; through several queries it is
now possible to analyze all the recording and elaborations steps made for
stratigraphic interpretation.

La rivoluzione digitale in atto da un decennio ha completamente stravolto i
paradigmi del modo di concepire e fruire la cultura, comportando un profondo ripensamento delle interazioni reale-virtuale e fornendo possibilità e
potenzialità ancora pienamente da esplorare. La capillarità di diffusione di
dispositivi sempre più costantemente connessi ha cambiato la concezione
che gli individui hanno del contesto in cui sono calati, delle proprie capacità
e delle proprie possibilità relazionali: è interessante notare come, per agire
nel territorio reale, si sia sempre più spesso passati dal territorio digitale. Si
analizzerà pertanto l’approccio verso i beni culturali: in Italia si avverte un
saldo legame con una storia millenaria di cui ci si sente in qualche modo
eredi – riflettendo in questo appieno il termine anglosassone di heritage
– calati in un paesaggio a tal punto permeato di cultura da non riuscire a
trovare una linea di demarcazione tra singoli elementi di interesse e loro
contesto. Troppo diffuso da non essere valorizzato adeguatamente dallo
Stato, per mancanza di necessari fondi, per mancanza di personale, per
riassestamenti burocratici: ci si sente così in dovere di supplire alle mancanze strutturali organizzandosi, portando la community nella realtà e ridiventando comunità: in tal senso, una delle filosofie e uno degli strumenti
più utilizzato è costituito da Wikipedia. Si assiste così a diversi momenti
caratterizzati per un approccio squisitamente bottom-up, dal basso della
comunità di intenti verso l’alto del livello istituzionale, con forte impatto,
creazione di contenuti fruibili liberamente e in grado di attivare azioni di
innesco. Nascono così OpenPompei - Scriptorium, all’interno del Grande

patrimonio - materiale e immateriale - in pericolo a causa di calamità naturali; mAppiaM!, per coinvolgere la cittadinanza nella valorizzazione della

scoprire e conoscere gli aspetti meno della città. Si prenderanno in esame
i diversi progetti e le svariate iniziative incentrate sulla cultura collaborativa,
illustrando le metodologie via via adottate e gli strumenti adoperati, al fine
di individuare un modello incentrato sulla cultura libera per la valorizzazione territoriale in grado di generare anche un impatto economico.

La complessità genericamente riscontrata nella visualizzazione e analisi dei
segni grafici pertinenti al repertorio delle manifestazioni artistiche incise e
graffite di età preistorica rappresenta un ostacolo ricorrente alla comprensione dei caratteri del sistema grafemico-simbolico condiviso dai gruppi di
cacciatori-raccoglitori di cultura paleo-mesolitica.
Le tecniche consolidate di rilievo grafico e fotografico della ricerca archeologia, ad ogni modo risorse preziose per una documentazione indispensabile, sono oramai integrate da pratiche metodologiche e strumenti di indagine di acquisizione digitale dei dati mediante procedimenti di lavoro ed
elaborazioni informatiche.
Con il sostegno delle attuali metodologie e applicazioni digitali, l’analisi della
“grammatica dei segni” di età preistorica è virata verso l’indagine interattiva
42

degli oggetti al variare delle condizioni di illuminazione, che ne tenga conto
della visione globale dei valori plastici che assumono i singoli segni in relazione al proprio supporto.
La sperimentazione metodologica è stata avviata sul corpus di incisioni su
supporto calcareo recuperate nel corso delle indagini stratigrafiche presso
la Grotta di Santa Maria di Agnano (Ostuni, BR) e attribuite ad un contesto
rituale del primo Olocene: alla visione monoculare del microscopio digitale
è stata integrata una documentazione fotografica ad alta risoluzione, calibrata sulla tecnica di acquisizione e di elaborazione di immagini, denominata Reflectance Transformation Imagining (RTI).
Basato sull’algoritmo opensource polynomial texture mapping (PTM), aggiornato e sviluppato dall’University of California Santa Cruz e la Cultural
Heritage Imaging ©, il software libero RTIBuilder esegue un processo di
mappatura polinomiale delle superfici, elaborando una serie di immagini
del soggetto da una singola posizione e in condizioni di illuminazione variabili: stabilito sia un oggetto statico che una vista fissa della camera, l’applicativo codifica il valore di ogni pixel del frame fotografico e calcola le funzioni
di riflettanza dai dati acquisiti, rendendo possibile una fruizione analitica
del soggetto in modo interattivo.
Il vantaggio di questo metodo, già ampiamente verificato e validato, è la
possibilità di creare, all’interno del software visualizzatore RTIViewer, un
ambiente di illuminazione virtuale con molte luci, ognuna delle quali consente di aumentare il contrasto locale di una piccola porzione del manufatto, che di solito occupa alcune centinaia di pixel; il rendering non foto-realistico prodotto da questo ambiente virtuale di illuminazione non è
riproducibile nel “mondo reale”: il fine scientifico della tecnica è ottimizzare
una misura di perfezionamento che massimizzi la nitidezza dell’immagine
e allo stesso tempo preservi la luminosità diffusa, garantendo un miglioramento generale della percezione della forma e dei dettagli più particolari,
incrementando lo scenario di dati sensibili da esaminare.
VIRTUAL ARCHAEOLOGY FOR THE LITTLE GUY? A CASE-STUDY
BASED ASSESSMENT OF THE FEASIBILITY AND SUSTAINABILITY OF
MINIMAL RESOURCE VR MODELLING AND ITS APPLICABILITY TO
SMALL-SCALE ARCHAEOLOGICAL RESEARCH
Ben Price
email@diggah.net
https://www.researchgate.net/profile/Ben_Price4
Ben Price is currently finishing his PhD project on Virtual Landscape tools using games
engine development suites and how they can be used as a low-cost avenue for tool creation. He has the dubious distinction of having worked in both professional computer
games development and archaeology and has a passion for exploring new ways of
using computer technology to investigate the past. Previous projects have included his
masters which resulted in the 3D printing of an Atlantic Iron Age bronze pin from the
shattered remains of its clay moulds.
The prevalence and sheer accessibility of computer games engines has
been a revolution in the indie games development scene for a number of
years now, and use of games engines in archaeology is certainly no new
thing, but can this free resource be used for non-games related tools for
archaeological investigation and if so can it be done without the backing of
a multidisciplinary team?
In my recent PhD thesis, I attempted to answer just this question and explore the realms of free to use and open source tools to create a Virtual Reality tool that can investigate virtual landscapes produced with LIDAR and a
smattering of reconstructed models. The goals of the investigation were to
see what the pitfalls were along the development track and whether these
could be overcome by a single developer, whether such a tool was even
feasible with a games engine (in this case the Unreal Engine 4) and what
impressions such a tool would have on archaeologists familiar with the real
landscape. This paper is a summarisation of that thesis, discussing how this
accessible method of application creation can not only provide an academically beneficial method of investigation but also show that it is affordable
and within the means of dedicated people to produce.
44
ArcheoFOSS | 2020
The free development tools used were the Unreal Engine 4 by Epic Games which is royalty free for free projects, the Cloudcompare open source project, and the GDAL open source toolset for geographic data. Other
software that was used was free for students but not generally free, such as
Autodesks Maya, Allgorithmic (now Adobe) Substance. Other free resources
were used such as a plethora of free plugins for the Unreal Engine, all with
the aim of keeping costs as low as possible.
In essence the project proved that yes, it is possible to produce such a
tool but the process (currently) is not for the fainthearted. However recent
additions to the Unreal Engine have the potential to significantly improve
the workflow resulting in faster conversion of LIDAR data to 3D landscapes.
The paper discusses all these options and includes a look at the future of
games engine use within archaeology as a cheap development tool.

del Museo delle Culture ‘Villa Garibaldi’, Presidente di Una Quantum inc., co-referente
di ‘CIRCUITI’ Laboratori di innovazione tecnologica presso il Museo Nazionale Etrusco
di Villa Giulia, co-ideatore e concessionario del ‘Digital Excavation project 2019’ Bomarzo-Lugnano in Teverina, ex curatore del Museo Civico Archeologico ‘Rodolfo Lanciani’.
Il presente intervento parte dall’esperienza manageriale degli ultimi tre
anni dell’autore e intende mostrare una panoramica delle diverse soluzioni
open-software e open-hardware utilizzate al fine di implementare le capacità evocative, comunicative, interattive ed economiche del museo. La
possibilità attuale di utilizzo di strumenti FLOS per costruire le comunità e
gestire i luoghi culturali è varia, seppur non ampia. In particolare si parlerà
dell’esperienza dell’autore e del suo gruppo di lavoro sull’utilizzo dei seguenti software: Pannellum per la costruzione dei Virtual Tour del Museo
Lanciani e del Museo Nazionale Etrusco di Villa Giulia, Glamkit come piattaforma CMS per la pubblicazione online e LOD del patrimonio museale,
QGIS per la mappatura e la ricontestualizzazione dei reperti nel territorio,
Pyarchinit per lo studio dei siti territoriali e la loro stratigrafia, Blender per la
costruzione di modelli architettonici di monumenti, oggetti, ambientazioni
e rendering, Cura per la stampa 3D delle opere ai fini dei percorsi multisensoriali e merchandising e FreeCAD per il rilievo architettonico e il dialogo
con i laser cutter. Tuttavia, la possibilità di utilizzo della filosofia FLOS non
è unicamente legata all’applicazione, sviluppo e produzione di soluzioni
tecnologiche; se progettata in maniera oculata, una strategia manageriale
open, può giovare alla gestione delle strutture, incrementare il business e
agevolare la costruzione e la crescita numerica e scientifica delle comunità
museali.
Nella seconda parte del presente contributo verrà quindi esplicato un modello di managerialità legato in maniera inscindibile alle soluzioni FLOS,
46
ArcheoFOSS | 2020
mostrando i modelli di business-plan che ne derivano, con la possibilità di
accedere a sempre nuovi impulsi economici e crescita per gli allestimenti.
Con pochi accorgimenti e implementazioni tecnologiche le strutture museali possono ospitare laboratori e corsi professionalizzanti FLOS, utili a loro
volta per: la progettazione, la costruzione di percorsi multimediali e multi-sensoriali, la prototipazione del merchandising; avvicinando alla struttura nuovi tipi di pubblico, attraendo nuovamente le comunità politiche,
imprenditoriali e industriali locali e internazionali.
Si tratterà di un modello sostenibile per la costruzione di reti interpersonali
innovative, volto alla crescita delle nuove generazioni e dei professionisti
nella conoscenza delle tecnologie in contesti profondamente culturali.
Si traccerà infine la strada futura verso la fusione tra Museo e Fab Lab,
per sancire la nascita e la crescita dei FLOS-Museums in grado di ospitare
assieme alle opere: incubatori di progettazione permanente, atelier per la
costruzione di installazioni e merchandising, padiglioni e mostre temporanee, opifici di sperimentazione di supporti e sistemi espositivi in grado di
essere replicati ed esportati, centri all’avanguardia di formazione, valorizzazione, diagnostica, restauro per la conoscenza scientifica dei beni esposti e
la crescita delle comunità.

Julian Bogdani

https://iris.uniroma1.it/browse?type=author&authority=rp62440
Julian Bogdani is researcher of Archaeology at Sapienza University of Rome. He is member of the ERC Advanced grant PAThs - An Archaeological Atlas of Coptic Literature,
directed by Paola Buzi. He teaches Digital Humanities and Methods of Archaeological
Research at Sapienza. He has developed many open-source applications specifically
designed for archaeology and cultural heritage needs.
The paper is aimed at sharing with the broader community some methodological issues and practical solutions that have been faced and dealt with
while working on the drafting of the Archaeological Atlas of Coptic Literature, in the context of PAThs ERC Advanced project directed by Paola Buzi
and based in Sapienza University of Rome.
The premises where canonical: in order to design specific cartographic and
topographic themes to be published in the Atlas (https://atlas.paths-erc.
eu) a significant amount of previously published maps of various scales
had to be digitized and vectorized. This material was quite heterogeneous,
under multiple aspects. Scale, graphical styling, topographic accuracy, degree of interpretation, reconstructive hypothesis varied greatly from one
map to another. The maps of the buildings related to the Christian cult —
basilicas, churches, chapels, etc. — were digitized and georeferenced. This
first step of the workflow would require a paper on its own since multiple
technical and substantial (i.e. archaeological) issues are involved. The digitization and vectorization process took, on the other hand, the shape of an
actual legacy data recovery action aimed at porting to the digital domain
paper-based sketches. The most important task was to overcome the risk
of creating a CAD-based, muted vector theme, a sort of digital-analogical
copy of the paper version. It was decided thus to enrich the vector features
with semantics, through the drafting of a simple but powerful schema able
to encode concisely but exhaustively all sort of information that a common
52
ArcheoFOSS | 2020
archaeological and/or architectonic sketch is able to convey. Moreover,
metadata on where the original drawing can be found and on the person
who performed the vectorization have been encoded. The resulting protocol named PAThs Simple Vectorization Protocol, or simply SVP, has been
released as a Free Cultural Work with the Creative Commons Attribution
4.0 International License.
This methodological approach considers the georeferencing and vectorization processes not as a purely mechanical or join-the-points one, but as a
critical archaeologic reading and interpretation of the original drawing and
its translation in digital format. The interpretation of the surveyor flowed
into the paper-sketch and the one of the operator who deals with many
versions of the same context must be clearly set apart in order to be able
to easily distinguish the different contributions and possibly integrate more
recent works, contributing greatly to the transparency of the scientific process.
When it comes to semantics, the protocol is chronology- and context-agnostic. This means that even if it has been developed to solve a very specific
archaeological problem — i.e. the vectorization of sites and buildings related to the cult of the Christian religion in Late-antique and Medieval Egypt
— it can be used profitably virtually in any cultural or chronological context.
The SVP provides means to thoroughly describe extant or hypothesised
structures, their state of preservation and the relative chronology (i.e. phases). The protocol aims to be an objective tool for vectorization, trying not
to force over-interpretation when information is lacking, but it is designed
also to provide useful tools for multi-layer hypothesis by maintaining the
overall transparency of the entire data production and manipulation process.

editoriale della rivista Archeologia e Calcolatori, di cui cura in particolare la gestione
dei metadati bibliografici.
Open Access e Open Data – trasparenza, riproducibilità e condivisione
– sono le due istanze fondamentali dell’Open Science, la scienza partecipativa, intesa come divulgazione e partecipazione attiva. Da diversi anni
la politica del CNR è orientata verso questa direzione, come testimoniato
dalla partecipazione dell’ente a infrastrutture di ricerca digitale anche nel
settore dell’Heritage Science, quali E-RIHS (http://www.e-rihs.eu/) e Iperion
CH (http://www.iperionch.eu/).
Sostenere l’innovazione nella conoscenza, conservazione e valorizzazione
dei beni culturali, sviluppando l’Open Science per la condivisione dei dati
scientifici è una delle mission dell’Istituto di Scienze del Patrimonio Culturale (https://www.ispc.cnr.it/it_it/), un hub di nuova formazione, che ha
raccolto l’eredità pluriennale della linea di ricerca dedicata all’Informatica
archeologica nata agli inizi degli anni Ottanta e poi sviluppatasi intorno alla
rivista open access Archeologia e Calcolatori (A&C).
Il paper proporrà alcune riflessioni sul ruolo sempre più significativo delle
riviste scientifiche come luogo di pubblicazione dei risultati delle ricerche e
di promozione delle buone pratiche della filosofia open. In questo ambito,
A&C ha assunto nel tempo un duplice ruolo: da una parte si è proposta
come aggregatore internazionale di progetti, idee e riflessioni, dall’altra è
stata una fucina di sperimentazione e riflessione focalizzata soprattutto
verso Open Science e risorse digitali aperte in archeologia.
Intorno ad A&C si è formato oggi un Laboratorio interdisciplinare di archeologi, filologi, matematici e informatici, la cui opera non si è limitata all’attività scientifica e di redazione, ma si è posta obiettivi più ampi, mirati al
monitoraggio e allo studio di tecnologie di gestione ed elaborazione delle
informazioni per favorire la fruizione di collezioni di open data in ambiente
digitale.
Il repository degli articoli di A&C, conforme al protocollo OAI-PMH, contiene
oggi i metadati di più di 1000 risorse digitali, consultabili in accesso aperto dal sito web, per un totale di oltre 15.000 pagine (http://www.archcalc.
cnr.it/). Questo ampio repertorio ha avuto anche l’obiettivo di fornire alla
comunità scientifica una fonte di informazioni specialistiche accessibili e
connesse con altre informazioni in rete, permettendo alla rivista di essere
allineata alle più attuali tendenze internazionali verso la scienza aperta e il
web semantico.
Book of Abstracts | 2. Open data, open formats, open standards

L’interoperabilità garantita dalla conformità agli standard internazionali per
la creazione dei metadati e per la loro esposizione ha consentito ad A&C di
contribuire ad iniziative di aggregazione di contenuti culturali digitali. Quello di A&C è il primo dataset relativo alla produzione di una rivista scientifica
ad essere stato reso disponibile in CulturaItalia nel 2017 (http://www.culturaitalia.it). Dal 2020 A&C è presente anche nel portale Europeana con oltre
900 risorse (https://www.europeana.eu/) (Fig. 1). Grazie all’attuale lavoro di
mappatura dei metadati delle risorse secondo le più recenti linee guida di
OpenAIRE (https://www.openaire.eu/), la rivista sarà a breve content provider della principale infrastruttura europea di Open Science per la comunicazione dei risultati della ricerca.
Sempre nell’ottica della condivisione di risorse scientifiche in rete, in occasione dell’uscita del 30mo numero è stata sperimentata l’applicazione
ai testi di A&C di strategie di webmapping secondo i criteri offerti dall’open source international tool Recogito (https://recogito.pelagios.org/). Tale
mappatura geografica è stata eseguita sugli articoli pubblicati nelle annate
edite tra il 2014 e il 2018 e su una selezione di testi (editi dal 1990), in cui si
fa riferimento a siti etruschi. La finalità è stata quella di rendere i toponimi
citati negli articoli dei linked open data, che risultano consultabili in Pelagios
Commons, attraverso il suo motore di ricerca geografico Peripleo (https://
peripleo.pelagios.org/) (Fig. 2).

Francesca Forte vanta al suo attivo diverse pubblicazioni ed esperienze internazionali
con importanti centri di ricerca (CISA UNIOR di Napoli, Vast-Lab, Cyprus Institute, Scuola

ha collaborato al corso di “Topografia antica” presso l’Università “L’Orientale” di Napoli.
Le reti satellitari GPS, le celle radio utilizzate per la telefonia mobile e l’emergente Internet of Things, consentono di tracciare e correlare la posizione di persone e oggetti in modalità talmente precise fino a poco tempo fa
impensabili; per questo motivo, all’interno del flusso di dati che vengono
raccolti quotidianamente, i dati geo-spaziali occupano un posto rilevante
nella prospettiva dei big data.
Nel 2017 l’OGC (Open Geospatial Consortium) ha pubblicato un white paper con l’intento di definire approcci più efficienti per il trattamento dei big
60
ArcheoFOSS | 2020
data geo-spaziali. Attraverso l’identificazione di best practice per far fronte
alle moderne sfide di gestione di grande quantità di dati, è possibile usufruire di nuovi strumenti e tecnologie per gestire la visualizzazione, l’analisi
e l’integrazione dei big data geo-spaziali, riuscendo finanche a individuare
correlazioni sconosciute e ad estendere i domini di conoscenza. Un ruolo
chiave nel processo di creazione di infrastrutture di gestione dei big data
è occupato dagli standard aperti. Tale approccio garantisce l’affidabilità dei
dati, permette la loro corretta divulgazione e ne consente un valido riutilizzo in diversi domini di applicazione.
Nell’ultimo decennio, anche nell’ambito della ricerca archeologica sono state pienamente comprese le potenzialità dell’utilizzo dei formati standard
per la pubblicazione in rete di banche dati territoriali e dei relativi risultati
di analisi geo-spaziali. Parallelamente, si è assistito a una proliferazione di
standard e di formati aperti di interscambio, nonché di direttive nazionali ed Europee: tra queste ultime si segnala la direttiva INSPIRE emanata
con l’obiettivo di favorire la creazione di una infrastruttura nazionale per
rendere omogenee e condivisibili informazioni geo-referenziate di carattere ambientale. L’Open Geospatial Consortium conta, ad oggi, 69 standard
per la descrizione di dati geografici. A questi si aggiunge lo SHAPEFILE, un
formato proprietario oramai divenuto uno standard per l’analisi spaziale.
Con queste premesse, è facile intuire come i ricercatori – anche in campo archeologico - spesso si trovino davanti a una moltitudine di formati,
standard e non, tra cui risulta difficile orientarsi nella scelta, soprattutto in
funzione della visualizzazione, della long-term preservation dei dati e della
interoperabilità delle banche dati geografiche.
Il dato spaziale in archeologia ha un’importanza straordinaria nella ricostruzione del passato consentendo a vario livello di individuare pattern
territoriali oppure di localizzare funzioni particolari all’interno delle aree
urbane. Per queste esigenze specifiche di ricerca la registrazione spaziale
dei dati riveste un ruolo determinante nel processo di ricerca archeologica
e quindi di comunicazione soprattutto nell’ottica della condivisione dei dati
aperti. Ma l’archeologo stesso, a sua volta, adopera informazioni spaziali già
presenti sulla rete e messe a disposizioni da altre istituzioni di ricerca, di
gestione o di pianificazione del territorio.
Questo contributo intende fornire un’analisi sugli standard utilizzati nelle banche dati online e nei geo-portali regionali e nazionale, per quel che
riguarda le informazioni archeologiche, effettuando una mappatura delle
risorse presenti in rete, per individuare gli effettivi livelli di interoperabilità.
Particolare attenzione è stata posta al confronto tra i formati standard mag-

giormente presenti nelle infrastrutture digitali per descrivere le singole risorse (es. GML), i geo-database (es. GeoPackage) e la sfera 3D (es. CityGML),
individuandone punti di forza e criticità. L’obiettivo è stato quello di evidenziare le caratteristiche tecniche dei formati analizzati, per comprendere quali
siano le strategie e le prospettive e come questi dati possano interagire in
modo efficace con differenti applicazioni in campo archeologico.
DEVELOPING LONG-TERM INFRASTRUCTURE FOR OPEN

world). He also provides consulting services and IT training to DAI staff, project partners
and international beneficiaries. His main area of technological and scientific expertise
is that of spatial data processing and statistics, including geoinformation systems (GIS),
spatial data infrastructures (SDI), remote sensing, image-based (SfM/MVS) 3D reconstruction, sensor data processing and archaeological predictive mapping.
This paper discusses the design and current state of development of iDAI.
world (https://idai.world), the open research data infrastructure of the German Archaeological Institute (DAI: Deutsches Archäologisches Institut). The
ultimate development goal of iDAI.world is to provide a modular, Web-based FAIR implementation with exhaustive support for all main categories of
archaeological research data.
A network of many different departments and research units, spread
across several continents, the DAI is an archaeological microcosm in itself,
reflecting the diversity of the discipline’s practice and research. And iDAI.
world, in turn, represents this institution’s paradigmatic shift toward digital
research and open data infrastructures. Currently available modules cover
the following, principle types of research data:
- iDAI.objects (a.k.a. Arachne): object-centric, well-structured datasets of
common research categories (sculptures, buildings, building parts, ...), with
strong support for secure and fast image hosting (https://arachne.dainst.org)
- iDAI.gazetteer: authoritative registry of ancient and modern places, with
a hierarchical data model and support for multiple translations/transcriptions of place names (https://gazetteer.dainst.org)
64
ArcheoFOSS | 2020
- iDAI.geoserver: geodata repository that supports seamless upload and
management of common GIS data products, as well as data styling and
thematic map production; based on GeoNode and Java GeoServer as middleware, and thus implementing OGC GIS protocols (https://geoserver.
dainst.org)
- iDAI.field 2: a field data (excavations, surveys, etc.) client with offline and
synchronisation capabilities, with a flexible data schema that can be adjusted and extended to suit specific project needs (http://field.dainst.org)
In addition, iDAI.world includes modules for bibliographic research, standardized vocabularies, open access publications and other tools that assist researchers in producing and publishing consistent, interoperable research data.
With its early roots in the traditional server-client architecture of the late
1990s, iDAI.world, through the diversity of its components, reflects the evolution’s dynamics of two decades of software development: in-house development vs outsourcing, project-focused and top-down vs needs-driven
and agile development, have all been complex issues that played a role in
shaping this digital infrastructure. Accordingly, many (sometimes expensive)
lessons have been learned, regarding the sustainable and long-term development of open source research software.
The biggest obstacles are often not of a purely technological nature, but related to the effects that technological innovations and disruptions have on
research traditions, as well as to the sheer complexity of modern software
development.
In a research environment where ideas and opinions (“interpretations”), as
well as access to primary sources of information (such as excavation licenses) have traditionally been regarded “academic currency”, and where progress and career paths were long associated with personal merit rather
than collaborative scientific rigor, the ideals of reproducible research and
the sheer scope and demands of open science meet considerable inertia.
On the other hand, writing software is easy (children can learn to program),
but designing and implementing digital infrastructures that will (hopefully)
one day prove at least as useful and lasting as printed publications, is a
tremendous undertaking for which no simple “solutions” exist.
Consequently, some of the most valuable lessons learned within the context of iDAI.world will be shared in this paper, touching on technical as well
as economic and social complexities.

in Contemporary Archaeology. She deals with archaeological methods, archaeological
open data, archaeological potential and archaeological communication. She has been
project and communication manager of ArchAIDE project (http://www.archaide.eu).
This paper is focused on one of the less-known aspects of the ArchAIDE
project: the open data policy and the management of material covered by
copyright. The ArchAIDE project developed a system for automatic recognition of pottery with an innovative app for tablets and smartphones. This
goal has been implemented through the development of two distinct neural
networks for appearance-based and shape-based recognition and lays on
the creation of a digital comparative collection, incorporating existing digital
collections, digitised paper catalogues and multiple photography campaigns. For achieving the correct management of the material which falls under
copyright or database protection, the EU directives on Copyright (2001/29/
EC) and Database protection (96/9/EC) were analysed. The scientific research exception permitted the implementation of the project, in particular, (i) as
regards the area of copyright: published works, mentioning the source and
66
ArcheoFOSS | 2020
the authors’ name, can be used to the extent justified by a non-commercial
purpose; the use of the structure of published databases can only be used,
mentioning the source, to the extent justified by a non-commercial purpose; (ii) as regards the sui generis right: databases can be used, even if scientific research is not its sole purpose, mentioning the source and the authors’
name, to the extent justified by a non-commercial purpose. This does not
mean the ArchAIDE project necessarily holds the copyright to the newly digitised, remixed data. Whether these data can be made available outside the
project would need to be negotiated with each copyright holder. Showing
the potential of digitising paper catalogues in a way that demonstrates how
their content can be actively reused allows ArchAIDE to open a discussion
with publishers and other data providers about the importance of making
their resources available in new ways, with a tangible benefit (seeing their
data in use within the app), thus furthering the long-term discourse around
making research data open and accessible.
Participating in the H2020 open data pilot, ArchAIDE was committed to creating sustainable outputs where the project held the copyright. This included
making the interoperable, multilingual vocabularies, and the video corpus
created by the project available, as well as the 2D and 3D models created
from the ADS archive Roman Amphorae: a digital resource. This aspect of
the archive represents a good exemplar of best-practice reuse. When this
digital resource was first deposited in 2005, creating automated 2D and 3D
models that could be used to create ‘virtual sherds’ to train the deep learning algorithm could not have been a use envisioned. As 2D and 3D models
were created for every type from Roman Amphorae, it was possible to link
the two archives, amplifying the usefulness of both. The ArchAIDE archive
includes 2D vector drawings in SVG format for download, and 3D models for
interactive use within the 3D viewer (created using 3DHOP). The 3D models
can also be downloaded for use with 3D software and 3D printing.
It was also hoped the thousands of photos taken by the project for training
the algorithms, might result in new comparative collections that could be
made freely available as part of the ArchAIDE archive. Still, intellectual property rights in many European countries are restrictive and did not allow
photos taken by ArchAIDE partners of sherds held in national and regional
collections to be made available. It is hoped that seeing the usefulness of
these data within an example application such as ArchAIDE may also help
convince the holders of these resources to move towards more open data
policies. Finally, the source code and neural network models will shortly be
made publicly available as open source.

Marco Ciurcina, avvocato iscritto all’Albo degli Avvocati di Torino dal 1994. Opera nel
campo del diritto commerciale, societario e contrattuale, diritto dell’Information Technology, diritto d’autore, brevetti e marchi, in particolare con focus su software libero,
contenuti e dati aperti.
I concetti di software libero e copyleft nascono alla fine degli anni ‘80, quando la diffusione del personal computer e delle prime BBS danno origine a
un’utenza privata dell’informatica. Le pratiche e le normative esistenti mal
si adattano ai nuovi modelli produttivi e comunicativi proposti dalle nuove
tecnologie e si rende necessario stabilire nuove regole in grado di stare al
passo con la rapida evoluzione di hardware e software. È così che vengono
ideate licenze in grado di tutelare i produttori di software ma al contempo anche di favorire la diffusione e divulgazione delle loro creazioni. Nei
primi anni ‘90, il rapido sviluppo del web crea un nuovo forte divario tra la
legislazione esistente e le innumerevoli possibilità di condivisione offerte
dalla rete e, anche grazie alla spinta di associazione e movimenti come l’Electronic Frontier Foundation o il movimento per l’Open Access, i concetti di copyleft e di licenza libera si diffondono rapidamente anche a dati e
contenuti. Un nuovo punto di svolta si ha circa una decina d’anni più tardi,
quando Cloud e servizi web cominciano a entrare nell’uso comune. Il supporto fisico di dati e contenuti non è più detenuto da chi li produce, ma ubicato altrove e l’accesso è regolato da licenze di servizio. Ora ai movimenti e
70
ArcheoFOSS | 2020
alle associazioni per i diritti digitali si affiancano spesso Antitrust e Garanti
Privacy nazionali, che intervengono frequentemente in casi di utilizzo non
appropriato dei dati: la loro tutela rappresenta ora la nuova frontiera per le
libertà digitali. Tale repentino sviluppo tecnologico ha portato anche chi si
occupa di beni culturali e di archeologia a riflettere su leggi e regolamenti
non più adatti alle modalità digitali di archiviazione e divulgazione. Seppure
con un certo ritardo, nascono in Italia movimenti a favore dell’uso di tecnologie libere e dell’apertura di dati e contenuti, tra i principali: ArcheoFOSS,
che ha impresso una forte spinta alla conoscenza del software libero in
ambito archeologico, e il movimento Fotografie Libere per i Beni Culturali,
motore di un’importante iniziativa grazie alla quale dal 2017 i beni culturali
di proprietà pubblica sono liberamente fotografabili e divulgabili (fatto salvo lo scopo di lucro).
È indubbio che attualmente il software libero sia largamente impiegato nel
settore archeologico: solo per citare alcuni esempi, QGIS è tra i software
più diffusi negli scavi e negli studi territoriali; Leaflet e Geoserver sono tra
le tecnologie Web GIS più utilizzate, etc. Ci si chiede dunque se per i dati
e i contenuti relativi ai beni culturali e archeologici l’applicazione di licenze
libere sia diffusa quanto l’utilizzo di software libero. L’analisi delle principali
pubblicazioni dedicate a questi temi sembra evidenziare come software e
dati siano andati fin’ora a due velocità diverse: al grande utilizzo di software
libero non corrisponde un altrettanto ampio accesso ai dati. Le principali
cause di questo divario vanno ricercate nel contesto storico sopra citato: la
spinta all’accesso ai dati ha una origine più recente, inoltre pratiche e leggi
ancora non adeguate al ciclo di produzione digitale costituiscono spesso
un forte freno all’apertura. Un’ulteriore problematica è quella delle modalità di accesso: spesso i dati necessitano di un oneroso processo di rielaborazione e migrazione per poter essere esposti come “open data” e l’infrastruttura tecnologica disponibile non è adeguata. Non mancano tuttavia in
Italia esempi pionieristici che fanno ben sperare, come i progetti SITAR o
Mappa. In tale stato dell’arte si innesta una riflessione sugli scenari futuri.
Ancora una volta sembra profilarsi una doppia velocità: quella più rapida
dell’apertura dei dati, stante un processo in qualche modo già avviato, e
quella più lenta della predisposizione di infrastrutture e di servizi con termini d’uso appropriati. La nuova sfida del futuro sembra dunque essere la
tutela e conservazione del nostro patrimonio culturale digitale.

This paper deals with the data management of museum collections using
the specific case-study of the Libertini Collection kept at the Museum of
Archaeology of the University of Catania. Since the aim of the project is to
define forms of long-term preservation of digital data associated with sites
and objects of cultural interest, we used the Linked Open Data paradigm
Book of Abstracts | 2. Open data, open formats, open standards
73
and, more specifically, the Web Ontology Language, the standard language
for representing web ontologies, which are digital tools designed for the
definition, description, integration and sharing of resources of various domains of knowledge. Such an approach adds a high level of expressiveness
for the possibility of using automatic reasoning tools, which allows one to
obtain a more complete and comprehensive as well as more complex and
efficient form of digital research.
The digitization of the archaeological collection of the Museum of Archaeology of the University of Catania explores innovative models of data entry in
order to encourage not only new research by specialists, but also the discovery and interpretation of cultural heritage by a wider audience, including
university students who have been directly involved in the process of data
entry. All the finds will be made available and reusable online in an open
(CC BY-NC-SA 2.5 IT - Creative Commons) and connected format following
the spirit of a public, shared and participatory archeology. Moreover, the
core of the Museum are the 325 finds belonging to the collection that was
donated by G. Libertini to the University of Catania in 1953 (Fig. 1). The collection consists of finds from the Greek and Roman periods (i.e. fine and
common wares, epigraphs, terracotta figurines, coins, etc.) mostly unearthed in the archaeological sites of Catania and Centuripe areas. Among these are some noteworthy fakes (i.e., 78 objects forged in the first half of the
twentieth century) which for the outstanding level of craftsmanship and the
use of authentic molds deceived many archaeologists and art historians.
The decision to publish online the content of the G. Libertini Collection is
not only related with the quality of the finds, but also to the consistency of
the supporting documentation (i.e., catalogs, transmission letters, photos,
etc.). The project aims not only at reconstructing the history of the collection, but also at transforming it into a digital dimension through the processing, recovery and republication of the available legacy data. The project
will allow one to identify the context of scattered items and to relate the
copy of the item with the original, by means of an appropriate mapping
of the ontology with the RDF Pleiades vocabulary, according to the LOD
paradigm.
The first step saw the identification of the entities and their organization
intoa system that adopts the ICCD standards, with a view to a forthcoming
integration with the SIGECWeb (Fig. 2). For the development of an effective
and expressive ontological model, the preliminary phase is the normalization of the data acquired through museum resources and their organization into homogeneous and structured collections with adequately refined

level of granularity (Fig. 3). Specific terminological vocabularies of reference will be determined. The areuseful for normalizing data by means ofthe
identification of suitable and consolidated existing vocabularies and the
definition of new terminological entities. We will then rely on already existing ontologies on inherent domains such as OntoCeramic [1] and EpiONT
[2], defined according to the CIDOC standard for the integration of data in
cultural and archaeological contexts.

ArcheoFOSS | 2020
Editions of objects are a specific form of publication in archaeological science and play a central role in comparative and classifying research. They
comprise lists, tables, catalogues, atlases and corpora (Hofmann et. al.
2019: http://nbn-resolving.de/urn:nbn:de:0048-dai-edai-f.2019-2-2236).
As part of a research data management project of the Zentralen Wissenschaftlichen Dienste (central scientific services) of the DAI (www.dainst.org),
at the RGK Frankfurt we are currently transferring editions of objects to the
semantic web and utilising the possibilities virtuality offers. The selection
of editions follows three criteria: most importantly the edition has to be
widely accepted and continuously used in the scientific community. Hereby
substantial metadata can be extracted and there will most likely be a longstanding requirement for the data. Furthermore, the editions should be
published in the DAI or its departments so that copyrights and publication
rights are ensured. Finally, the data of the edition should be set out in a
form that enables them to be transferred to a database (DB), and data related illustrations should be available.
The Conspectus Formarum Terrae Sigillatae Italico Modo Confectae (https://
zenon.dainst.org/Record/000255878; in the following just Conspectus) is
an edition of objects, i. e. of plain Terra Sigillata (TS) (also known as Samian
Ware), that meets the criteria mentioned above. But other than being an
edition of objects it is a revision of prior classes and a synthesis of prior
classifications: It is an edition of classes.
It was compiled in the years between 1986 and 1990 by leading specialists
for TS, all of them members of the learned society Rei Cretariae Romanae
Fautores (https://www.fautores.org/). Their aim was to overcome the usual
geographically bounded classification that is based on the analysis of production sites, contexts or chronology. Instead they »have tried to systematize that knowledge in such a way that future researchers will find it helpful as a framework within which to arrange their own perceptions and on
which to hang future accretions of knowledge« [Conspectus, p. 2] An open
and future-oriented framework is a defining component of DBs (Burkhardt
2015: https://doi.org/10.14361/9783839430286-007) – but the data were
not recorded in a DB, although the technical possibilities were already at
hand in the discipline (Rösler 2016: https://www.academia.edu/38924456/)
Thus, the current transferral of the Conspectus’ data into a relational DB
is facilitated by their conceptual framework and their system of categories.
And beyond the mere reproduction of the conspectus, and by detachment
from paper, the data can now be worked with: it can be corrected, updated,
added, externally linked, and represented in numerous contexts.

In our contribution to the conference we would like to refer to the following
topics:
1. The data of the Conspectus should be presented in a relational DB. As
the metadata can and will be represented in other digital environments
such as the iDAI.world (https://idai.world/), the classification and classes
can themselves be represented in a relational DB. It is the classification
system that reflects relations examined by the scientific community, and in
our view this knowledge should be displayed as well.
2. The framework of virtuality allows us to play with the representation of
data. We would like to introduce a representational tool for the combination of rim-, wall- and base-forms of vessels that is based on open-source
software.
3. Open Data should not only mean data for free use, but it should also ensure the provision of access to the origin of the context the data was or is
represented in, if possible. In the case of the Conspectus we are working on
a historical and epistemological analysis of its development, and we would
like to present some results and discuss their contribution to the provision
of high quality data.

In this paper we present a project by the working group ‘Research Squirrel Engineers’ (http://squirrel.link) on the digitization and provision of Irish
Ogham Stones in Wikidata as Linked Open Data (LOD). Ogham Stones are
monoliths inscribed with the Ogham (ᚑᚌᚆᚐᚋ) script, erected in Ireland and
the western part of Britain (Wales, Scotland, Cornwall, Devon, Isle of Man)
between the 4th and 9th centuries. The standard work on Ogham inscriptions
is the Corpus Inscriptionum Insularum Celticarum (Macálister 1945,1949).
In it, Macálister establishes the widely used numbering scheme CIIC and
describes two different types of words: formula words and nomenclatu-
82
ArcheoFOSS | 2020
re words. Examples of formula words are MAQI ᚋᚐᚊᚔ (son, e.g. CIIC 203,
Q67978531) or MUCOI ᚋᚒᚉᚑᚔ (tribe/sept, e.g. CIIC 197, Q69388229).
Examples of name components (nomenclature words) are CUNA ᚉᚒᚅᚐ
(wolf/hound, e.g. CIIC 154, Q68002826) or CATTU ᚉᚐᚈᚈᚒ (battle, e.g. CIIC 58,
Q70892430). Other names refer to possibly divine ancestors, e.g. the god
Lugh (LUC ᚂᚒᚌ) appears in many names like LUGADDON ᚂᚒᚌᚌᚐᚇᚑᚅ (cf.
CIIC 4, Q70899515). The combination of formula and nomenclature words
leads to inscriptions that feature kinship or tribal relations. Examples are:
X MAQI Y → X son of Y (e.g. Q69389090) or X MAQI MUCOI Y → X son of
the tribe Y (e.g. Q69388229). These triples of information lend themselves
well to a representation as a linked-graph-network. So do the results of the
linguistic analysis of the stones: As the stones are often damaged, different
ways of reading and reconstructing them abound. These differing interpretations can be placed next to each other and easily expanded within a graph
database system. In addition, personal relationships and spatial topologies
can be visualized and analyzed very well with graphs. The major challenge,
though, is that all this data is available in books or non-open-access online
databases. Therefore, the Squirrels established a workflow for digitising the
analogue data and publish the ᚑᚌᚆᚐᚋ stones as LOD. The aim of our project
is to enable the reproduction of analyses based on the analog CIIC catalog
and enhance the database with Linked Open Data available online. By publication as LOD, the data becomes machine-readable, and available for any
interested person, thereby also enabling citizen scientists all over the world.
As we know, LOD has become the de facto “quasi-standard” for the storage of humanities data in a semantically modeled cloud. There are several
possibilities to host this modelled and published LOD: (a) create your own
ontology, formulate a triples creation process and host the triplestore with
a SPARQL endpoint or (b) use well-known community based systems, e.g.
Wikidata. Strategy A is based on an ontology (https://t1p.de/lnb9) with the
publication using a RDF4J triplestore (https://digits.mainzed.org/squirrels).
Strategy B uses the community approach: Wikidata. Wikidata allows for attribution, linking to other entities and the specification of provenance and
sources. Wikidata data can be filtered, exported and further processed
with different programs using SPARQL APIs, such as the SPARQL Unicorn
(10.5281/zenodo.3742185).
This paper will give a deeper insight into the two semantic (LOD) modelling
and publication strategies. We will discuss the pros and cons as well as the
challenges of the strategies. This includes in particular the major challenge
and possibility of citizen science vs. data sovereignty.

SITAR (Sistema Informativo Territoriale Archeologico di Roma - Archaeological Territorial Information System of Rome) has been launched in 2008
by the Soprintendenza Speciale per i Beni Archeologici di Roma in order
to digitize and gather all the scientific data coming from the archaeological
excavations and the geological research surveys carried out within the territory of Rome and Fiumicino (https://beniculturali.academia.edu/ProgettoSITAR).
Since the beginning, the main goal of the project was to provide to the
community involved in the study and preservation of the archaeological
and historical heritage of Rome with a useful support for the process of
urban co-planning. For this reason, unlike other similar experiences at national and international level, the representation is no longer symbolic, but

the archaeological data are processed in their “planimetric reality”, after an
accurate georeferencing process carried out by professional archaeologists. Today, the system brings together several types of data, ranging from
archival documentation to the single archaeological features found during
the archaeological excavations.
After 13 years from the development of the first web application, from
May 2018 a system re-engineering was started, aimed at merging the three
original applications (WEBAIS, SIGEDO, AMBIENTE TUTELA) into a single system.
The infrastructure is now hosted on the GARR cloud (based on the OS Open
Stack) and has a modular architecture, so that each service is allocated on
specific “container”, as shown in fig. 1. This choice stems from a twofold
requirement: on the one hand, to optimize the response to individual requests, and on the other to ensure a specific maintenance of the single
services.
Among the main innovations is the creation of a Digital Library, which allows the user to explore the SITAR documentary heritage (maps, drawings,
scientific reports), filtering the results through specific parameters (fig. 2).
The new Digital Library is served by the open source suite ELK: it uses ElasticSearch as a search engine, Logstash for the index creation and Kibana
to generate an effective view on the data. The documents are scanned
through OCR and the system can retrieve the keywords used to search
within every single document.
The final objective of the new engineering was to align SITAR with the FAIR
DATA philosophy and therefore to guarantee an easy and well documented
data acquisition. For this reason, SITAR data can now be acquired by any
user 1. through download in the main OPEN FORMATS (GEOJSON, GML2,
GML3, KML; GEOTIFF, GEOTIFF8, SVG, CSV: fig. 3), 2. through specific requests to the dedicated GEOSERVER instance or, at an upper level, thanks
to the REST services (fig. 4) . The publication of the API allows the users to
dynamically exploit the SITAR dataset, negotiating the protocol and the format according to its specific needs.
Finally, it is worth noting that the postgres/postgis SITAR database – that
currently stores 5.000 excavations, 25.000 archaeological features and
100.000 attachments – adopts CIDOC CRM Archaeo as semantic model
and the data have been extracted and represented in RDF, using the XML
language.

Emanuel Demetrescu, PhD, è ricercatore presso l’Istituto di Scienze del Patrimonio Consiglio Nazionale delle Ricerche. È sviluppatore python, pilota UAV, specialista in
Archeologia Digitale, Archeologia delle Costruzioni, modellazione 3D source-based
(ricostruzioni virtuali) e reality-based (creazione di repliche digitali). Le sue principali
ricerche riguardano la creazione di collegamenti teorici e metodologici tra la documentazione scientifica nei Beni Culturali e le industrie creative (librerie digitali 3D, musei
virtuali, giochi Open World ed esperienze di VR).
L’integrazione del tradizionale rilievo archeologico da campo con la fotogrammetria è un approccio metodologico che, in generale nell’ambito dei
Beni Culturali, si è andato via via consolidando soprattutto nell’ultimo decennio. In questo periodo, il continuo e crescente sviluppo tecnologico, la
disponibilità di nuove soluzioni software per la fotogrammetria e l’incremento delle performance degli strumenti dedicati all’acquisizione e l’analisi
dei dati hanno senza dubbio contribuito alla diffusione di questo approccio
combinato. Tuttavia, nonostante l’estrema potenzialità informativa derivata
dall’integrazione di questi dati, la scelta dell’ambiente di lavoro all’interno
del quale gestire queste informazioni appare ancora al giorno d’oggi una
questione aperta, spesso direttamente connessa allo scopo del progetto in
cui il dato fotogrammetrico viene impiegato.
94
ArcheoFOSS | 2020
In questo contributo si vuole descrivere la metodologia applicata all’interno
del software open-source Blender al fine di gestire un intero dataset fotogrammetrico, relativo ad un areale di circa 3000 mq, utilizzato come reference principale per la ricostruzione 3D del complesso forense di epoca
romana del sito di Nora (Sardegna, CA).
Tramite una serie di tool utili all’importazione, la georeferenziazione, la gestione, l’editing, la visualizzazione in multirisoluzione e l’esportazione di un
rilievo fotogrammetrico, l’addon 3D Survey Collection (3DSC) ha agevolato
l’interazione con l’intera mesh fotogrammetrica del foro. La gestione di tale
geometria tramite 3DSC ha permesso di pianificare, prima, e realizzare, poi,
la ricostruzione dell’intero complesso architettonico rimanendo all’interno
dello stesso ambiente di lavoro. Questo specifico addon è stato sviluppato
all’interno del Virtual Heritage Lab del CNR ISPC di Roma proprio con l’intento di limitare la segmentazione su più piattaforme software del flusso di
lavoro delle ricostruzioni 3D Reality Based, ossia quel metodo ricostruttivo
che assume il rilievo tridimensionale come dato di partenza da cui avviare
il processo di ricostruzione. L’applicazione di questo approccio metodologico, unito all’uso dell’applicativo 3DSC all’interno di Blender, ha permesso
di controllare ogni step del percorso ricostruttivo del foro romano di Nora
garantendo un confronto continuo tra il modello tridimensionale e il rilievo
fotogrammetrico. L’attuale release di 3DSC è una versione massicciamente
riscritta e con nuovi moduli previsti, che la rendono una novità sostanziale
a livello software e di workflow rispetto a quella presentata in occasione di
ArcheoFOSS 2019.
PUBBLICARE I DATI ARCHEOLOGICI CON A.R.C.A.: STATO DEI
LAVORI E PROSPETTIVE FUTURE
Irene Carpanese
irene.carpa@gmail.com
https://unipd.academia.edu/IreneCarpanese
Irene Carpanese si è laureata e dottorata presso il Dipartimento dei Beni Culturali
dell’Università degli Studi di Padova. Nel corso degli anni si è specializzata nel settore
delle nuove tecnologie applicate alle discipline archeologiche (database, modelli 3D, siti
web).
Nel 2014 ha iniziato a prendere forma l’idea che prevedeva lo sviluppo di
un software per la pubblicazione dei dati archeologici online. Il progetto
si è concretizzato nel corso di un Dottorato presso l’Università di Padova,
grazie al supporto congiunto di tre tutor provenienti da settori disciplinari
diversi (proff. Maria Stella Busana e Jacopo Bonetto, archeologi classici e il
prof. Nicola Orio, ingegnere informatico).
L’avanzare dei lavori è stato periodicamente documentato da pubblicazioni, che testimoniano l’evolversi (a tratti tortuoso) del percorso di ricerca. Nel
2019, con la fine del Dottorato, si è concluso il progetto; dopo aver lasciato
decantare il tutto per qualche mese, è ad oggi doverosa un’esposizione dei
risultati raggiunti e dei futuri sviluppi possibili, soprattutto a seguito di questa emergenza sanitaria che ci ha imposto una riflessione concreta sull’importanza dell’informatizzazione e l’apertura dei dati in ambito culturale.
Il nome del Progetto, A.R.C.A., è un acronimo delle funzionalità stesse del
prodotto, ossia di Archiviazione, Ricerca e Comunicazione del dato in Archeologia, ed è nato fin da subito con lo scopo di essere un software con
cui gestire in maniera semplificata i dati archeologici di varia natura (quindi
dal dato testuale a quello spaziale, passando anche per i 3D), impostato
come prodotto “scalabile”, ovvero riutilizzabile per diversi progetti e da differenti Enti in maniera autonoma, e semplice nell’utilizzo, in modo tale da
incentivare i detentori delle informazioni ad utilizzarlo per aprire i propri
dati in maniera trasparente.
Il software è completamente open source, sviluppato sullo stack MEAN,
96
ArcheoFOSS | 2020
composto da un framework, Angular, un server web, Express, su ambiente
Node.js. Rispetto ad altri applicativi, la caratteristica che contraddistingue
questo lavoro è l’aver scelto di utilizzare uno stack completamente ECMAScript, che si appoggia a un database di tipo noSQL, in questo caso Mongo.
Questa scelta è stata fatta per un motivo ben preciso: l’assenza di schema
tipico di un DB non relazionale contribuisce a rendere A.R.C.A. un prodotto
flessibile e altamente adattabile per progetti differenti per tipologia e presentazione dei dati, incentivando anche, in uno sviluppo futuro, la comunicazione tra dataset differenti, grazie alla possibilità di inserire i dati di più
progetti mettendoli in interconnessione tra loro.
In un momento iniziale era stato diffuso un questionario per comprendere
quali fossero le necessità dei possibili fruitori del pacchetto e come fosse
percepita la questione dell’apertura dei dati sul web; seguendo le indicazioni estrapolate è stato impostato A.R.C.A. Volendo mantenere questa politica di “progettazione condivisa”, al termine del lavoro, è stata impostata
un’ulteriore verifica, grazie alla creazione di un test di navigabilità dell’applicativo, finalizzato ad individuare aspetti tecnici problematici e apporre
eventuali modifiche.
A progetto concluso si può affermare che A.R.C.A. risulta un buon punto di
partenza, cosa che non deve essere vista come un fallimento della ricerca.
In questi anni infatti sono state impostate delle solide basi per sviluppare
un software che potrebbe avere grandi potenzialità, ma la sua crescita è
direttamente proporzionale al suo utilizzo da parte della comunità archeologica. Questo intervento mira dunque a focalizzare i punti di forza del
prodotto ma anche le lacune, presenti come in tutti i prodotti, che però
possono essere colmate dai fruitori stessi di A.R.C.A. Lo scopo è quello di
sollecitare ad una collaborazione collettiva, partendo dal download del codice disponibile online e iniziando ad utilizzare il prodotto cercando di farlo proprio, con modifiche e implementazioni, al fine di caricare i dati per
la consultazione pubblica. Questo per fare un passo avanti sì verso i dati
aperti ma soprattutto verso i dati condivisi, concetto di fondamentale importanza per la ricerca archeologica.

Archaeology revolves around a few questions: what was man like, his life
and his places over the centuries? Digital archaeology and virtual reconstructions offer concrete tools to take contemporary man back in time and
“visit” the places he came from: his past. A real time machine built over 200
years, from splendid painted reconstructions to immersive virtual reality
and open world video games.
In recent years the interest of the scientific community in virtual reconstructive hypotheses (the visualization of a context as it must have appeared
at a given time in antiquity) has grown. A central aspect in the development
98
ArcheoFOSS | 2020
of scientifically correct virtual reconstructive hypotheses is the possibility to
manage and publish not only the visual result of the reconstruction but also
all the data used to obtain it and in particular the sources, reasoning and
interpretations. This type of activity, however, requires complex cross-references of data, even very different from each other (written sources, photographs, photogrammetric 3D models, stylistic comparisons, etc.). In order
to achieve this goal, therefore, it is necessary both a theoretical framework
and a series of innovative computer tools that can simplify, standardize and
make efficient the workflow that leads from the archaeological data to the
reconstructive hypothesis: this is the focus of this article.
The proposed innovative tools are based on the Extended Matrix (EM), a
formal language able to manage both the archaeological record and to annotate the reconstructive hypotheses that emerged from the early stages
of the investigation. In other words, within the EM approach, it is possible
to transform the stratigraphic archaeological record into formalized reconstructive hypotheses about how a context must have appeared at a given
time in the past. The 3D tools are part of the Extended Matrix Framework:
the Extended Matrix tools (EMtools - https://github.com/zalmoxes-laran/
EM-blender-tools) and Extended Matrix Visual Inspector and Querier (EMviq - https://github.com/phoenixbf/emviq).
The software mentioned are just ones of the possible practical applications
of the Extended Matrix methodology. Thus, the development of these tools followed a bottom-up approach and started from real problems that
emerged during the development of some case studies as reported by archaeologists and 3D modelers involved. The software have been released
under an open source GPL 3.0 license in order to be used by the scientific
community and possibly modified to adapt them to their own case studies
within the same methodological frame-work of the Extended Matrix (examples of custom developments currently underway are the use of EMtools
for the taphonomic analysis and reconstruction). The article will shortly
present examples of workflow on real case studies and technical details
related to the operative aspects of the software.

Timo Homburg studied Computer Science with emphasis on Computational Linguistics, Semantic Web and Chinese studies and in the last years worked in the GIS field to
integrate geospatial data with Semantic Web technologies. His PhD thesis deals with
semantic geospatial data integration and the quality of geospatial data in this Semantic Web context. Another of his research interests is the Digital Humanities where he
published in the area of Digital Cuneiform studies.

Florian Thiery is a geodesist by training and Research Software Engineer and founder of
the Research Squirrel Engineers working group. He is a member of the Scientific Committee of the Computer Applications and Quantitative Methods in Archaeology (CAA) as
well as of the CAA Special Interest Group (SIG) on Semantics and LOUD in Archaeology
(SIG-DataDragon) and the CAA Little Minions Working Group. His research focuses on
semantics and data modelling, especially Linked Open Data in archaeology. He studied
in Mainz (M.Sc.) and worked at the Institute for Spatial Information and Surveying Technology in Linked Data projects like the Labeling System.
In our daily work, some small self-made scripts and home-grown small
applications significantly help us to get work done. These little helpers –
you can call them “little minions” – often reduce our workload or optimise
our workflows. Therefore, the `Computer Applications and Quantitative
Methods in Archaeology` (CAA) created a working group on `Little Minions` (http://littleminions.link) focusing on development and customization of FLOS Software for archaeology.
Furthermore, the WWW gives researchers the possibility of sharing their
research data and enables the community to participate in the scientific discourse to create previously unknown knowledge. But much of these shared data are not findable or accessible, thus resulting in modern ‘unknown
data dragons’. Often these ‘data dragons’ lack connections to other data-
102
ArcheoFOSS | 2020
sets. To overcome these shortcomings, a set of techniques can be used:
Semantic Web and Linked Open Data (LOD) (https://doi.org/10.5281/zenodo.3345711). This is where the CAA SIG on Semantics and LOUD in Archaeology (http://datadragon.link) comes into play and wants to promote the
LOD ideas. One of their tasks is to collect LOD related data e.g. Nomisma,
Kerameikos, Pleiades, AtlantGIS, Roman Open Data (http://dragonator.datadragon.link) to be used in research software.
Moreover, there are very cool volunteer community driven data collecting
initiatives like Wikidata. The Wikidata community created a lot of tools to
interact with the Wikimedia repositories. On the other hand there is a lack
of user-friendly, easy to use and openly available archaeology-related tools
for LOD as you can be seen in the collection of CAA Little Minions (https://
github.com/caa-minions/minions). The Digital Humanities Community may
use Recogito or Annotorious, to overcome this bottleneck, but for the archaeological community, the SPARQL Unicorn idea and principles may help
(https://doi.org/10.5281/zenodo.3742185).
To summarize the three aforementioned aspects, there is a lack of FLOS
GIS Tools for LOD and archaeology. The SPARQLing Unicorn QGIS plugin
addresses the problem of the lack of availability of tools for Semantic Web
geodata. It allows the execution of Linked Data queries in (Geo)SPARQL to
select triplestores and geo-enabled SPARQL endpoints and thus prepares
the results of the queries in QGIS for the geocommunity. The plugin currently offers three functions: (a) simplified querying of Semantic Web data
sources (b) enrichment of geodata and (c) enrichment and transformation
of RDF data.
The first function allows assisted querying of several triple stores, also using
columns of custom geo-datasets. Example queries and query templates
are given. A concept search simplifies the creation of the SPARQL query,
the results are saved as a QGIS vector layer. The Unicorn covers archaeological related triplestores e.g. Nomisma, Kerameikos, Pleiades, and Roman
Open Data. The second function allows the enrichment of a given geodataset using Semantic Web resources from the Linked Open Data Cloud, especially Wikidata (e.g. the elevation level of towns along the Roman Limes).
Geospatial data is always seen in a context of usage which usually requires
additional data from different knowledge domains. Semantically interpreted Linked Data may represent such a resource for data enrichment. Finally, the provision of geospatial and archaeological data into the Semantic
Web is of interest. Communities need appropriate tools to convert geospatial information e.g. from GeoJSON into RDF, so that this information might

103
be represented in a proper way. This is also of
interest to the Linked (Geo) Data community
whose interest is to reproject and transform
geospatial data into other reference systems.
The Unicorn is able to do this as well.

LEASTCOSTPATH: MODELLING PATHWAYS AND MOVEMENT
POTENTIAL WITHIN A LANDSCAPE
Joseph Lewis

https://josephlewis.github.io/
Joseph Lewis, University of Cambridge PhD, is an Archaeology student interested in the
Application of GIS to Archaeological Mobility and Settlement Patterns with a focus on
spatial uncertainty.
The movement of past peoples in the landscape has been studied extensively through the use of Geographic Information Systems (GIS) and Least
Cost Path (LCP) analysis (Batten, 2007; Bell and Lock, 2000; Fiz and Orengo, 2008; Güimil-Fariña and Parcero-Oubiña, 2015; Howey, 2007; Kantner
and Hobgood, 2003; Siart et al., 2008; Supernant, 2017; van Lanen et al.,
2015; Verhagen et al., 2014; Verhagen and Jeneson, 2012). By using terrain in conjunction with other factors that may have influenced movement
through a landscape, LCP models have been used to: identify long-distance
routes (e.g. Batten, 2007; Palmisano, 2017); understand road networks (e.g.
Bell et al., 2002; Fábrega Álvarez and Parcero Oubiña, 2007; Murrieta-Flores, 2012); and assess factors that were taken into account during route
construction (e.g. (Bell and Lock, 2000; Fonte et al., 2017; Kantner and Hobgood, 2003; Verhagen and Jeneson, 2012).
Despite developments in the application of using Least Cost Path analysis
to answer archaeological questions (e.g. Llobera, 2015; Verhagen, 2013;
White and Barber, 2012), the implementation of these methods remains
largely inaccessible, requiring individuals to develop their own solutions.
Furthermore, although the methodological issues of using Least Cost Path
analysis have been documented (e.g. Herzog, 2010; Herzog, 2011; Herzog,
2013; Herzog, 2014), little has been done to provide open source solutions
that incorporate these findings and make them accessible to users.
The R package leastcostpath¸ developed by the author, is open sourced
software for the calculation of Least Cost Paths and their derivatives, as
well as providing functionality to calculate slope-based cost surfaces that
106
ArcheoFOSS | 2020
incorporate cost functions such as the popular Tobler’s Hiking Function.
Furthermore, leastcostpath allows for the incorporation of other cost surfaces such as the attraction of features in the landscape, barriers to movement, and movement potential within the landscape. Lastly, the R package leverages the iterative nature of Least Cost Path analysis by separating
each step of the cost surface process into separate functions with easily
changeable parameters.

THE VIRTUAL COUNTRYMAN. A GRASS-GIS TOOL FOR ANCIENT
CULTIVATION IDENTIFICATION
Augusto Palombini

https://www.linkedin.com/in/augusto-palombini-50b1216/
Augusto Palombini, archaeologist, researcher at the Institute of Cultural Heritage Science of the Italian National Research Council, worked in archaeological missions in Italy
and Africa. Author of scientific and dissemination works, as well as 3 historical novels.
Founding member of the Italian Archaeologists Confederation. His research activity
is currently focu sed on landscape archaeology, virtual museums, digital storytelling,
computer science and multimedia solutions applied to Cultural Heritage and topographic surveying, particularly dealing with open source software (member of the Italian Scientific Committee on Free and Open Source Software in Archaeology).
As a relevant methodology literature has spread on 3D modeling of ancient buildings and monuments, it has not been the same about the reconstruction of landscape, intended as the whole vegetation cover and the
geomorphology, both natural and anthropic (cultivated land).
The author works in a research group which proposed ways to check and
reconstruct relevance and distribution of ecosystems, particularly dealing
with cultivated areas in relation to demographic data. Such activity was primarily conceived to perform 3D landscape models leaving from GIS maps,
through commercial soft ware (Visual Nature Studio, Vue+3dStudio Max,
etc.).
Nowadays, the aim is to propose a complete pipeline, to obtain, from digital cartography and anthropic indexes related to social complexity, ecosystems and cultivated areas, creating maps to be used by modeling software
to create 3D representation of landscape: a complete open source working chain script-connected through GRASS GIS, Blender 3D, Unreal Engine
and the web viewer ATON, as to create a landscape generator covering the
whole path from ecosystem theory up to immersive visualization.
Here, an early piece of such a chain is presented: a GRASS_GIS script aimed at semi-automatic predictive detection of cultivated areas.

Taking into account the digital elevation map (DEM), and its derivative features as slope, aspect, solar exposure, the tool creates an ideal cultivation
cover map, also influenced by settlements, pathways, water streams , and
giving all these aspects a relative weight in relation to social complexity (for
instance, a higher weight of paths for statal organized systems and a weaker one for prehistoric ones, closer to the site-catchment model). The tool
has been tested, with interesting results, against maps of known archaeological situations.
