INTRODUCTION AND BACKGROUND
This paper deals with opportunistic collaboration1 within the context of learning and earning, which are
increasingly important and interconnected activities in modern life. Unplanned opportunities for collaboration
arise naturally in our present mobile knowledge society, where increasing mobility brings both people and ideas
into contact faster than ever before. In this context, ‘mobile knowledge’ has at least two different meanings: (i)
knowledge that moves (= disseminates), and (ii) knowledge that is created and communicated by mobile agents.
In the mobile knowledge society, knowledge is disseminated at an ever-increasing rate, and more and more
mobile knowledge agents are coming into play.
The effects on learning, introduced by this type of mobility, is a matter of intense research. The approach of the
London Mobile Learning Group (Pachler, 2009) is based on a mobile complex that operates within a sociocultural ecology. This ecology consists of agents, who interact with each other within different structures, and
who behave according to various cultural practices (Pachler et al., 2009). Learning is viewed as culturally
situated meaning-making, where each learner forms her own personal learning habitus, largely driven by the
normalization of mobile devices in everyday life.
A key aspect of the socio-cultural ecological approach to education (Pachler, 2009) is the increasing
individualization of risk-taking. In education, the responsibility for meaning-making is being transferred from
the state to the individual, which is reflected in the shift in educational rhetoric from ‘teaching’ to ‘learning.’ It is
also related to the ongoing fragmentation of mass communication, driven by the emergence of social media.2 A
key aspect of the mobile complex is the increasing interrelation of Internet services with user activities around
mobile devise use. All these characteristics of mobile learning promote opportunistic collaboration in a multitude
of different ways (Bruns, 2009b). In fact, young people constantly make use of social media on mobile devices
to collaborate opportunistically. “Who will join whom at what party” is an example of a frequently recurring
problem domain for such collaborations.
The advantages of the opportunistic collaboration patterns that are made possible by using mobile devices in
social interactions are being exploited in many different ways. Calling your wife on her way home from work
and asking her to pick up something that you suddenly found missing for your dinner cooking is a familiar
example from family life. Within traditional (= broadcast-oriented) media, many big news sites (such as e.g.,
CNNiReport3) have areas where anyone can upload material that could be interesting for the “news makers” to
broadcast. The big news networks know that they cannot control who will be standing next to an interesting
news item of today - with access to a camera to document it. They also know that the number of potential
eyewitnesses with documenting capabilities has increased beyond the wildest expectations of anyone from 20
years ago, and today covers almost half the population on this planet. This type of spontaneous “media
swarming” is well known (and often feared) by all celebrities who are monitored by our present “mobile-littlebrother society”. Whenever a celebrity shows herself in public, little brother sees her and immediately uploads
the documentation 4 to prove it. This type of opportunistic media swarming is also justly feared by politicians that
have an opposition to oppress, which was recently demonstrated by the efficient use of Twitter in the
orchestration of election protests in Iran.
Another interesting example involving a synchronous form of opportunistic collaboration is CITIHAIQ, a
system for opportunistic car-ride sharing that is being developed in Sweden, and which is planned to be launched
during 2010. By sending an SMS to a server, a person can announce that she is going to drive from A to B and
that she is willing to take passengers. At the same time other persons can inform the server that they are looking
for a ride from C to D. Based on location information and declared intentions, the server can then figure out
opportunistic matches between the set of drivers and the set of potential passengers – and inform the
corresponding people about suitable meeting points to take advantage of the ride-sharing opportunities that
happen to be available.

i.e., unplanned, unexpected, or ad-hoc collaboration. See http://en.wikipedia.org/wiki/Opportunistic_collaboration
as YouTube, Flickr, Twitter, etc. Kaplan and Haenlein (2010) define social media as "a group of Internet-based applications that build on
the ideological and technological foundations of Web 2.0, and that allow the creation and exchange of user-generated content.”

Opportunistic (l)earning in the mobile knowledge society 2010-03-29)
Ambjörn Naeve, the KMR-group, Royal Institute of Technology, Stockholm, Sweden
Synchronous communication depends on finding a time slot “that works” for everybody. In our time-poor
‘busyness’-driven society, where we increasingly find ourselves involved in mobile and multi-tasking activities
there is a shift in emphasis of communication modes. We are decreasing our dependence on synchronous
communication modes (such as face-to-face meetings, or telephone conferences) and becoming increasingly
dependent on more asynchronous modes (such as e-mail, Twitter, Facebook, …). 5 Moreover, an increasing
number of synchronous events are being recorded in a media-rich way and made available for asynchronous
access whenever the interested viewer/listener has some time to spare. This trend is clearly visible in mainstream
media, with the launching of a large number of media websites that provide asynchronous access to their already
broadcasted programs.
According to Pachler (2009), “mobile devices have the potential to move the learning experience from the
artificial confines of the classroom and out to more naturalistic field settings.” This puts tremendous stress on the
traditional curriculum-based educational system, which is almost totally based on laying a planned path into the
future. It is a major challenge to integrate the planned collaborative structures of traditional education with the
new “mobile opportunities” (for both planned and unplanned collaboration) in a way that can increase the
interest and motivation of young learners to tackle intellectually challenging material. As described by Pachler
(2009):
We are concerned about the dangers of a failure of the education system to keep pace with the
developments around meaning-making in the context of media use in the life-worlds of young people
and society more widely and argue the need for a purposeful ‘push’ in approaches to mobile learning
in all sectors of education in order to avoid a potential disconnection between the way young people
operate in their everyday lives and the way educational institutions interact with them.
In his excellent and thought-provoking book The Age of Unreason, Charles Handy (1989) shows how the same
underlying pattern is applicable to our work life in general. In work – as well as in education - there is a shift
from planned to unplanned collaboration. We are used to thinking of work in terms of life-long employment,
climbing up a highly visible and desirable ladder of professional promotions. This planned-carrier work has
traditionally been carried out in terms of meticulously planned collaboration between employers and employees,
within the legal framework of stable companies.
Over the last few centuries, corporations have been allowed to grow into organizations of unprecedented power.6
This has been accepted by society largely because, as employers, the big corporations have been able to provide
jobs for large parts of the population. In fact, this provision has been a fundamental part of the social contract.
However, in the ‘knowledge economy’ of today, this contract has been thoroughly revised. The ‘labor market’
has changed 7, and the traditional work-relations have been fundamentally transformed. In fact, our work-life is
starting more and more to resemble what Handy (1989) calls a work portfolio. This can be seen in many ways,
from the increased official worshipping of the ‘entrepreneurial spirit’ to the spectacular rise of a plethora of
different ‘staffing companies’ that can deliver the type of employees-on-demand that an increasing number of
employers seem to prefer.
In this paper I aim to show how we can make use of the Knowledge Manifold information architecture to support
opportunistic collaboration - both in work processes and within educational systems. In fact, I will illustrate how
we could transform a traditional Unemployment Agency into what could be called an Opportunistic
Collaboration Agency and how we can make use of the same pattern to open up education to non-traditional
groups of informal learners. The OCA pattern reflects a strategic shift in the way we manage our work
distribution processes, a shift that is already going on in society. Just as we must harness the power of mobile
devices for learning, we must harness the power of the Internet for creating portfolios of (work) opportunities for
people. It is no coincidence that dating services are among the most popular services on the net. Professional
group dating services is what an OCA can and should provide.
If we fail in supporting this strategic shift, we risk creating a disconnection that is analogous to the one that is
described by Pachler (2009) and cited above. In this case it is a disconnection between the way our work-life
actually functions, and the way that we organize ourselves around and within it - a disconnection that will make
us miss many opportunities to work and create value together.

“Just send me an e-mail about it” is a line that is often overheard today in mobile conversations.
See (Bakan, 2004) for an illuminating account of this development.

The traditional labor market is characterized by the interaction of potential employers and employees. In German / Swedish, the employers
are called Arbeitsgeber / arbetsgivare (= giver of work), and the employees are called Arbeitsnehmer / arbetstagare (= taker of work). Hence,
the German/Swedish labor market is a market where there are no buyers and sellers, but instead there are givers and takers. And it is a
market where the takers somehow assume that they have the right to be given something.

Ambjörn Naeve, the KMR-group, Royal Institute of Technology, Stockholm, Sweden
Below I will discuss how to turn an unemployment agency into an opportunistic collaboration agency that
supports people to explore, capture and realize their collaborative potential – especially people that are finding it
increasingly difficult to “find a job” within the traditional labor market. In Opportunistic Collaboration, the
major collaborative commitments are made at run time, as opposed to what happens in Planned Collaboration
where these commitments are made at compile time. Therefore, enabling and supporting OC means that we
should create systems and services that make it possible for people to collaborate in unexpected and unplanned
(ad-hoc) ways. As pointed out by many researchers, such as e.g., Handy (1989), and Gorelick et al (2004), the
rigidity of traditional organizations makes them less and less able to respond properly to many of the challenges
that face us today. Senge (1990, 2006) emphasizes the need for organizations to become learning organizations,
that can apply what Argyris and Schön (1978) call double-loop learning, in order to change their mental models,
i.e., their ingrained ways of thinking about what they do and why they do it.8 According to these organizational
researchers, successful organizations are busy with flattening their organizational hierarchies and introducing
more process-oriented and opportunistic ways of working together.
In education, opportunistic collaboration is a strong trend that is reflected in a shift of focus from teaching to
learning within a social context. Life-long, flexible, collaborative, and personalized learning are words that are
increasingly used in places where education is discussed and designed. They express important wishes that imply
new demands on learning architectures, with regard to pedagogy, organization and technology.
The traditional educational architectures are based on teacher-centric, curriculum-oriented, knowledge-push. The
new demands are largely concerned with a shift along all of these dimensions in order to support more learnercentric, interest-oriented, and knowledge-pulling types of learning architectures (Naeve, 2001a,b, 2005). At the
same time, within most organizations, new demands are being placed on effective knowledge management.
Promoting the creation and sharing of knowledge in order to assure the right person with the right knowledge in
the right place at the right time at the right cost is the overall aim of these demands. In the (present) words of
Wikipedia:9
Opportunistic collaboration is emerging in knowledge organizations. As Chatzkel (2003) asserted, a
knowledge organization “needs to nurture its people so that they feel free to move about in their
organization, to group and regroup in different configurations as needed, and to rework themselves
and their resources in concert with their new conditions.” (p. 20) It is a promising direction to explore
this design in educational contexts. A recent study (Zhang et al., 2006) indicated that the opportunistic
collaboration model led to a high level of collective responsibility, more pervasive, flexible,
distributed collaborations, and greater diffusion of information and knowledge advances.
Due to the rise of social media, the traditional roles of producing and consuming ‘knowledge’ are increasingly
challenged by knowledge ‘prosumers,’ people that simultaneously produce and consume knowledge.10 Peter
Drucker has coined the term “knowledge workers” for such people. Taken together, these individuals and their
organizations form the basis of what we call the “knowledge economy” or even the “knowledge society.” Today
there is wide consensus among politicians and economists that developing and strengthening the knowledge
economy should be the main strategy for the developed countries to maintain a competitive edge in the
increasingly global economy.
In this paper I aim to show how a group of knowledge prosumers can act together within a knowledge manifold
type of information architecture that could be called a prosumer manifold. The main argument of this paper is
that such prosumer manifolds can enable and support opportunistic collaboration in a number of new and
important ways.

THE KNOWLEDGE MANIFOLD: CONTENT IN CONTEXS THROUGH CONCEPTS
The terms single-loop learning and double-loop learning were introduced by Argyris and Schön (1978) in order to deal with the difference
between learning that does not change the underlying mental models of the learner but merely revises their application scenarios (singleloop), and learning which does affect such changes (double-loop). In his excellent article “Teaching Smart People How to Learn,” Argyris
(1991) argues that most people define learning too narrowly as mere “problem solving”, so they focus on identifying and correcting errors in
the external environment. This is what Argyris calls single-loop learning.

which, of course, is what everyone does all the time. What actually makes someone a knowledge worker is the fact that some organization
is willing to pay for the dissemination of the knowledge that is being produced, inside and/or outside the organization itself.

The work within my research group11 is based on the fact that knowledge management ideas and Semantic Web
technology can promote opportunistic collaboration by capturing essential knowledge, refining it through open
dialog, and making it available within a global, asynchronous, public service system in the form of a web-based
and globally accessible knowledge- and learning management environment (Naeve et al., 2005). Our way to
orchestrate such a system is in the form of a knowledge manifold (Naeve, 2001a), an information architecture
that will be briefly described below.
2.1. Overall architecture
When applied to education, a knowledge manifold is an open educational architecture based on learner-centric,
interest-oriented “knowledge-pull,” which is designed to support inquiry-based and customizable forms of
networked learning. A knowledge manifold consists of a number of linked information landscapes (contexts),
where one can navigate, search for, annotate and present all kinds of electronically stored information. A KM is
constructed by conceptual modeling of a specific knowledge domain in order to capture its underlying thought
patterns in the form of context-maps. The KMR group makes use of the KM architecture to construct a form of
conceptual web 12 (Naeve 2005) which functions as a conceptual interface to the underlying (machine) semantic
web.
A knowledge manifold has the following major characteristics:
• It can be regarded as a form of knowledge patchwork, with a number of linked knowledge patches, each with
its own knowledge gardener.
• It gives the learners the opportunity to ask questions and search for live knowledge sources to discuss them
with.
• It has access to distributed archives of resource components, which are described using standardized metadata
annotations.
• It allows teachers and learners to construct customized learning modules by composing (aggregating) resource
components.
• It makes use of conceptual modeling in order to construct context maps whose concepts (and concept
relations) can be filled with content. This supports the separation of content from context and promotes the reuse
of content across different contexts.
• It contains a concept browser, which is a type of knowledge management tool that lets the user construct and
navigate the context maps and view the content.
2.2. The concept browser Conzilla
Over the last decade, the KMR-group has developed a number of tools that support the collaborative
construction and connection of content and contexts in the form of knowledge manifolds, notably the electronic
portfolio system Confolio 13, and the concept browser Conzilla 14 with its collaboration service Collaborilla.
These tools are based on Semantic Web technology, which enables them to partake in the web of linked data15
that is emerging based on the vision of Tim Berners-Lee from 1998.16
Conzilla (Naeve, 2001b; Palmér and Naeve, 2005) is a concept browser, or a conceptual web browser, which is
designed to support the overview of complex information structures by enabling a multitude of different
strategies for information hiding. Conzilla supports the construction, navigation, annotation, and presentation of
the contexts, concepts and content stored in the form of a knowledge manifold. In fact, Conzilla presents content
in contexts through concepts. A concept is regarded as the boundary between its inside, which contains its
content, and its outsides, which represent the different contexts (maps) in which the concept appears. By rightclicking on a concept, one can navigate between all the different contexts where this concept appears. This type
of contextual neighborhood navigation provides a very powerful way to cross reference information and browse
through conceptual information landscapes.

Collaborilla (Ebner, et al, 2007) is a collaboration service within Conzilla, which enables the publication of
different parts of collaboratively constructed context-maps from different sources. Collaborilla enables us to:
• reuse and extend contributions published by others.
• create new context-maps that include existing concepts and concept-relations from other publishers.
• add content to the contributions of others.
• add comments (metadata) on the contributions of others.
By using Conzilla / Collaborilla, a knowledge manifold can be constructed in a collaborative fashion - reusing
globally identifiable concepts across different contexts. Conzilla/Collaborilla can handle collaborative contexts,
and Confolio can handle collaborative content. Both of these tools are designed to be connectable to mobile
devices in various ways. Especially interesting in the short term is the scanning and uploading of information
from mobile devices to Confolio. This will enable local communities to contribute information that can be
collaboratively contextualized on the web.17 We believe that this type of interaction is a key aspect of a global
asynchronous public service environment that can help us to harness the power of opportunistic collaboration.

FROM UNEMPLOYMENT AGENCY TO OPPORTUNISTIC COLLABORATION AGENCY
The automating of work is one of the main drivers of unemployment, (the fear of) which in turn is one of the
main drivers of life-long learning. The idea is that when we have been (or when we are threatened to be)
replaced by a machine,18 we will be able to pick up new skills that make us ‘employable’ again, i.e., attractive in
the “labor market.” Today, the traditional notion of long-term, steady work seems to have more or less
disappeared, and has been substituted by the modern ideas of ‘flexibility’ and “temporary staffing.”
As described above, in these more and more rapidly changing times, many companies are discovering the value
of opportunistic collaboration in more or less autonomous teams.19 In this section I will apply the same idea to a
person – or a group of persons - that are unemployed or underemployed.20 How could he/she/it be given effective
and efficient access to possibilities of opportunistic collaboration?
A group of collaborating agents can be organized into a supply-support network of entrepreneurial achievers that
are assessed in terms of how well they deliver on their promises (Figures 1-4). Below I will refer to such an
arrangement as an entrepreneurial network or an opportunistic collaboration network.
Figure 1.
Achieve–Supply–Support-Assess: The basis of an entrepreneurial network
The achievers of an entrepreneurial network are assessed according to the symmetric difference between what
they promise to deliver (at project-contract-time) and what they actually deliver (at project-run(out)-time):
Assess(Achiever) = Promised ∆ Delivered = what the Achiever promised but did not deliver, and
what the Achiever delivered but did not promise (to deliver).
17
For example, people with some time on their hands can use their mobiles to scan prices of different products that tend to vary a lot (such as
e.g., the local vegetable prices in Sweden), and upload this information to a Confolio folder that is connected to a Conzilla map that shows in
which of your local shops that the cheapest tomatoes are available today.
18
in the knowledge economy most often by a piece of software.
19
This is why Peter Senge (2006) considers team learning to be one of the five disciplines of a learning organization.
20
In Swedish, “unemployed” people (“arbetslösa”) are also called “free-placed” (= “friställda”).

Ambjörn Naeve, the KMR-group, Royal Institute of Technology, Stockholm, Sweden
The ideal value of this measure is the empty set. Then the achiever has delivered exactly what it promised – and
nothing else. Of course, the ideal is to deliver what you promise, but sometimes this turns out to be impossible
because you did not receive the things that you needed in terms of supply and/or support. This situation is
discussed in section 3.2 below.
3.1. The OCA – a professional group dating service
Imagine that when you enter an unemployment agency looking for a job, you would be able to search and
browse through a large variety of partially filled in process networks.21 Moreover, imagine that when you found
a network that interested you, you would be able to address some of the unfilled needs by specifying what you
could promise to deliver to whom, and under what circumstances you could make that promise. More precisely,
in order to satisfy the needs that you are interested in fulfilling, what would you yourself need, in terms of
supplies and support from others, in order to be able to deliver what you promise?
Let us consider a (presently) un(der)-employed agent A22 that enters an Opportunistic Collaboration Agency
(OCA). In order to find out about the available options, the agent A starts to traverse the Work Opportunities
Map (WOM),23 which is part of the Opportunistic Collaboration Network (OCN) maintained by the OCA. The
WOM is connected to the needs that are expressed by the participating agents. Here the agent A browses some of
the potential (= partially filled-in) collaboration networks that are of interest to it.
If the agent A finds some needs that it thinks it can fulfil (under certain conditions), it can register both its
ambitions and its corresponding needs with the OCA.24 The information entered into the OCN would be of type
“I can deliver this, provided that I am supplied with that and supported by that.” Having described how it could
make a contribution towards filling the available needs (= work opportunities), the agent A then becomes
represented by a process module inside the OCN.25 As seen in Figures 2-4 below, the needs that are displayed in
each interaction map are linked directly to the WOM.
Figure 2.
The potential work-relation A-supply-B, discovered by the system. In its role as a supplier of B, the agent A, in
turn, needs to be supplied and supported by other agents in order to carry out its promises as stated in the contract with B.
Figure 2 depicts a situation where the agent A, based on the information it has fed into the system, has been
informed by the system that A might be able to act as a producer (in this case a supplier) to fulfil some needs
that have been expressed by the agent B. Hence, in this interaction, A is a producer and B is a consumer. As a
21
Such as described in (Naeve et al., 2008).
This could be a single person, or it could be a group of persons acting as a unit in this context.

This is not shown in any of the Figures.

supplier to the agent B, the agent A in turn needs to be supplied and supported by other agents in order to carry
out its promises as stated in the contract with B.
Based on the information provided by A, the system can now suggest suitable “resource maps” for A that
involve other agents that could potentially satisfy the needs of A in the context of A acting as a supplier to B. By
indicating such an interaction map as interesting, A becomes represented on this map as a potential consumer of
services. Hence, A can switch the context on the A-supply-B relationship (Figure 3) and navigate to any of these
potential resource maps (suggested by the system) to negotiate their corresponding opportunities. In Figure 3, the
system has suggested one such resource map (Prosumer (A) – Supplier (E) – Supporter (F)) – and the figure
shows the agent A choosing to navigate to this map. It is important to notice that this navigational context-switch
is performed on the A-supply-B relationship, which is highlighted in Figure 3, and which has a unique identity in
the system. This unique identity forms the basis of the legally binding contract that may eventually be formed
around this relationship (see below).
Figure 3.
Switching context on the A-supply-B relationship and navigating to a resource map suggested by the system.
Figure 4 shows this resource map for the A-supply-B relationship.26 Here, the system has selected the agents E
and F as a potential supplier respectively supporter of A. In this context-map the agent A can explore the
conditions under which E and F are prepared to offer their services, and contact them electronically for further
discussions. At the same time, when the system finds that E and F could potentially supply and support A in
fulfilling its A-supply-B relationship, the system looks for suppliers and supporters of the corresponding needs
declared by E and F in order to fulfil their promises to A.
Let us assume that the agent A eventually finds that if it is properly supplied (by E) and properly supported (by
F), then it can promise to deliver what B needs. The agent A then informs the system that the possible workrelations with B, E, and F form an acceptable basis for real negotiations. The system then informs B, E, and F
about the decision made by A, and asks them if they would be prepared to participate in such negotiations.
26
The highlighting of the A-supply-B relationship in Figure 4 indicates that this map has been entered by context-switching on the A-supplyB relationship (as shown in Figure 3).

Figure 4.
A resource map for the agent A with respect to the A-supply-B relationship.
If the potential contracts are acceptable also to the agents B, E, and F, the system sends an invitation to the
negotiations of three interrelated formal contracts: A-supply-B, E-supply-A, and F-support-A. Such negotiations
will probably involve some face-to-face meetings between the negotiating parties. However, if a certain level of
trust has already been established between the involved agents, these negotiations could also be performed
online.
If the conditions are favourable for all involved agents, a contract of collaboration is formed between them. This
contract is based on the needs of the potential consumers and the promises of the potential producers (= suppliers
and supporters). It specifies how the declared needs of the consumers are going to be met by the producers. In
our case, it specifies that A will supply B with what it needs - under the condition that A will be supplied with
what it needs from E and supported with what it needs from F. The consequences of defaulting on your promises
form an important part of the contract.
In this way, the system can recursively set up entire value chains that involve such prosumer contracts in several
steps. This introduces both problems and strengths. For example, a problem that needs to be addressed is what
part of the contracts to expose to whom. For competitive reasons it is not always possible to allow everyone to
have access to everything about the contracts. However, the public parts must be informative enough to support
assessment in retrospect (Korfiatis and Naeve, 2005), which is a fundamental aspect of supporting the
emergence of high quality interactions. An important strength is the possibility of increased transparency along
the entire value chain of economic activities, which, for example, would make it easier to monitor the adherence
to environmental restrictions and make it harder for corporations to conceal their sweatshops and child workers.
3.2. The prosumer assessment metric
At the signing of the contract (contract-time = compile-time) each producer promises to produce something.
Later (at the end of the project) the producer has hopefully delivered what was promised. Seen from the other
side, at contract-time, every consumer specifies a need of something, and later, hopefully receives what was
needed from the corresponding producer(s). At the end of the project, a producer’s achievements is always
assessed with respect to the extent to which it has delivered what it has promised (to deliver). The assessment of
a consumer’s satisfaction is always performed with respect to the extent to which it has received what it actually
needed. The assessment of a prosumer’s achievements is a combination of the producer and consumer
assessments, which can be expressed as:
What was promised but not delivered and what was delivered but not promised, given the fact of
what was needed but not received and what was received but not needed. We can write this as:
Assess (Prosumer) = Promised ∆ Delivered | Needed ∆ Received
Opportunistic (l)earning in the mobile knowledge society 2010-03-29)
Ambjörn Naeve, the KMR-group, Royal Institute of Technology, Stockholm, Sweden
This prosumer assessment metric measures to what extent a prosumer has delivered what it has promised – under
the extent to which it has received the supply and support that it needed in order to carry out its promises. Note
that in the A-supply-B and A-support-B relationships, what was promised is assessed by both A and B, what was
delivered is assessed by A, and what was needed and what was received is assessed by B. During the running of
the project, the work-plan of a contract is evaluated at certain control points. At the end of the project there is a
special evaluation when all the promises should have been turned into deliverables. Sometimes there is a strong
disagreement between the producer’s opinion about what was delivered and the consumer’s opinion about what
was received. A contract normally specifies how to handle such situations.
A fundamentally important issue for increasing the quality of performance of the participating prosumers is
that each prosumer maintains a public description of its activities,27 where the prosumer explains what it has
promised and delivered, under the circumstances of what it has actually received out of what it needed - and was
promised by its suppliers and supporters - in order to fulfill its own promises. Moreover, these track records, in
the form of opinions from all agents involved in each transaction, can be aggregated with opinions from other
stakeholders in the transaction, using Semantic Web-based annotation techniques (Naeve, 2005).
3.3. Closing the loop: Multi-dimensional bartering in prosumer value loops
In some cases the value chains described above could close up into what can be termed Prosumer Value Loops.
Such PVLs are characterized by the fact that the needs of the bottom-level suppliers and supporters correspond
to services that could be delivered by the top-level agents. The OCA system could be instructed to indicate the
presence of such PVL possibilities, which are indicators of possible bartering loops that need not involve the
exchange of money. An example of a very simple PVL is described in Figure 5.
Figure 5.
A simple prosumer value loop: The teacher teaches math to the car-fixer,
who fixes the car for the babysitter, who closes the loop by babysitting for the teacher.
In fact, these PVLs form the basis of a multi-dimensional bartering system, where each participating agent is
represented by a prosumer matrix which lists what it makes and what it wants, as indicated in Figure 5. This type
of informal matrix economy has a number of potential advantages. For example, (i) it could support the emerging
multi-dimensional “work portfolio economy” that is described by Handy (1988), (ii) it could provide a form of
social defense against the increasing instabilities of the financial economy28, (iii) it could help diminishing the
growing economic divide between the ‘haves’ and the ’have nots’ (of jobs and/or money), and (iv) it could
contribute to a more sustainable future by minimizing material transportation through favoring loops that keep
such transportations as local as possible.
In fact, similar bartering systems already exist. One example is the LETS system, which is a locally initiated,
democratically organized, not-for-profit community enterprise which provides a community information service
and records transactions of members exchanging goods and services by using the currency of locally created
LETS Credits.29
27
This is analogous to an income tax declaration.
See Kurtzman (1993) for an informed account of the dangers of the present financial system.

EDUHAIQ: THE OPPORTUNISTIC LEARNING ACTIVITY BROKER
Let us return to the CITIHAIQ system for opportunistic ride sharing in cars that was described in the
introduction. By applying the OCA pattern from the last section in a slightly different way we can produce what
could be called the EDUHAIQ system – the opportunistic learning activity broker.
Imagine that educational institutions would have offers available online where people could sign up to learning
activities30 - such as lectures, seminars, individual knowledge counseling, etc - that have space available for
participation. This may sound a bit far-fetched, but, just like a driver going from point A to point B in the
geographical terrain, an educational institution has lots of “knowledge-drivers/facilitators” that are traveling
from A to B in their personal knowledge spaces, while trying hard to help the learners to make the corresponding
journey in their personal knowledge spaces. The main difference from the driver picking up passengers is that
the lecturer/facilitator cannot be sure that a learner is in fact at the point A, which is conceived as a pre-condition
to the fact that s/he will have a reasonable chance to get to the point B – guided by the skillful navigation of the
facilitator(s) of the learning activity.
4.1. The pre- and post-requisite competences of a learning activity
As described by Naeve et al. (2008), a learning activity can be modeled as a process module with pre-requisite
and post-requisite competences. The pre-requisite competences describe a pre-condition that corresponds to the
knowledge that is required of the learner in order to engage with the learning activity in a fruitful way, and the
post-requisite competences describe a post-condition that corresponds to the knowledge that will ideally be
gained by the learner after having finished the learning activity – if the pre-condition was satisfied.
Figure 6 shows two kinds of pre-requisite competences: supply competences and support competences. The
underlying idea, discussed in (Naeve et al., 2008), is that a learner’s supply competences for a certain learning
activity are planned to be refined when the learner engages in that activity, i.e., they are planned to be explicitly
discussed and improved, while the learner’s support competences for the same learning activity are considered
necessary background knowledge in order to meaningfully engage in this activity. However, the support
competences will normally remain tacit, i.e., taken for granted, and used implicitly during the learning activity
without being explicitly discussed and problematized.31
Figure 6.
Learning Activities as Prosumers
Hence, being at the point A in the “knowledge terrain,” from which the “learning journey” starts means to have
the pre-requisite supply- and support competences for being able to participate in the learning activity as it has
been planned by its organizers/facilitators. This is a pre-condition for the learning activity to be able to deliver as
promised and lead to the desired post-requisite competences.
The needed pre-requisite competences of the learner can be assessed in a pre-test and the promised post-requisite
competences are traditionally assessed in some form of post-test (exam). If the learner did fulfill the precondition, but was not able to reach the post-condition, it can be concluded that the learning activity did not
deliver in the way that was promised. Of course, there could be many reasons for this failure, but at least it can
30
that are synchronous or asynchronous, online or offline.
As an example from mathematics, high-school knowledge about limits and continuity can be considered supply competences for an
undergraduate calculus course, whereas basic arithmetic knowledge about integers and fractions can be considered support competences for
such a course. The learner’s understanding of limits and continuity will be substantially refined and improved during the calculus course, but
the ability to operate with integers and fractions will be taken for granted and not explicitly discussed during the calculus course.
31

Ambjörn Naeve, the KMR-group, Royal Institute of Technology, Stockholm, Sweden
be deduced that these reasons are related to the learning activity in question, and not to some deficiencies further
down the learning-chain.32
4.2. Orchestrating learning activities in supply-support networks
As shown in Figure 7, learning activities can be orchestrated in supply-support networks. To a certain extent this
is actually done within educational institutions when constructing a traditional curriculum. In this case, the
learning activities normally correspond to entire courses, and the curriculum connects these courses by stating
that passing certain courses is a pre-condition for being allowed to take other courses. However, in order to
incorporate informal learning, we can think of learning activities as being much smaller, consisting for example
in learning to understand a certain concept or group of concepts. In areas such as mathematics or physics, this
division of courses into learning activities that deal with clusters of related concepts is rather straight-forward,
whereas in other areas, such as history or literature, it is more complicated.
When the learning activities are combined into supply-support networks, the OCA contracts of the previous
section appear in the interfaces between them, as can be seen in Figure 7. Just as before, the Promised-Needed
part of the contract is planned in advance, whereas the Delivered-Received part is the result of a learner actually
engaging in the corresponding learning activity.
Figure 7.
A supply-support network of learning activities
4.3. Creating a prosumer loop by engaging in a learning activity
Figure 8 shows a learner engaging in a learning activity through different access modes that constrain the learner
in various ways. For example, certain learners have physical access to a lecture, where they can interact with the
lecturer and each other in a traditional face-to-face mode, while other learners have managed to acquire
electronic access in various forms, such as video, audio, chat, etc. In the EDUHAIQ system these access modes –
normally the electronically mediated ones - will be dynamically allocated “just in time” – as opposed to a
traditional educational system where all access modes are statically allocated - normally a long time in advance.
By engaging in a learning activity, a learner creates a prosumer loop around this activity. As shown in Figure 8,
the learner aims to obtain some competences that are felt to be needed, and selects a learning activity that
promises to deliver these competences under certain pre-conditions. The learner then (implicitly or explicitly)
promises to satisfy these pre-conditions by being in position of the pre-requisite supply- and support
competences for this learning activity. The learner then delivers on this promise by her/his actual performance
when engaging in the activity. The outcome of the activity, i.e., what the activity has in fact delivered, is that the
learner has received some competences that have increased the knowledge base of the learner in some way.
32
This type of pre- and post-condition tests is related to a software engineering principle called “design by contract.”

A learner creates a prosumer loop by engaging in a learning activity
Since the contractual interfaces of the OCA pattern appear both in the pre- and post-interfaces between the
learner and the learning activity, the prosumer assessment metric can be applied at these interfaces. The learner
can assess to what extent s/he received what s/he needed from engaging in the learning activity, and the
organizers/facilitators of the learning activity can assess to what extent the activity actually delivered what it
promised with respect to this specific learner, under the extent to which the learning activity actually received
what it needed from the learner in terms of pre-requisite supply- and support competences.

CONCLUSIONS
In this paper I have discussed how the concept of opportunistic collaboration is promoted by several social and
technological changes, and how these changes can be applied to the areas of learning and earning. I have tried to
demonstrate how these ideas can be combined to transform a traditional unemployment agency into an
Opportunistic Collaboration Agency with an entrepreneurial network structured as a prosumer manifold. The
OCA pattern provides ways to: (i) capture the dynamics of the entrepreneurial work-relations that are emerging
in the mobile knowledge society, (ii) increase the transparency of the entire value chain of economic activities,
and (iii) create prosumer value loops that can support multi-dimensional bartering. Moreover, I have applied the
OCA pattern to education, indicating how the resulting EDUHAIQ system could help bridging the gap between
formal and informal learning.
My overall aim has been to show how the OCA pattern can address some of the major problems that our society
will have to deal with in the near future. Supporting dynamic work relations – and bridging the gap between
formal and informal learning - is vital for the emerging work portfolio society, increasing transparency of
economic value chains is necessary for abolishing the inhumane forms of labor that goes on in the hidden
corporate sweatshops all over the developing world, and the multi-dimensional bartering system could make
important contributions to bridging the economic divide by increasing the opportunities for marginalized groups
of people to create value together.
At the bottom of these issues lies a conflict between the selfish and unselfish perspective on knowledge. Two
thousand five hundred years ago, the pythagoreans taught us that unselfish knowledge is the best way to purify
our souls. Today, economists and politicians tell us that selfish knowledge is the best way to fill our wallets.
Hence, the catharsis-oriented knowledge philosophy of the pythagoreans has been complemented with the
utility-oriented knowledge economy of the modern information society. The vision of this emerging knowledge
economy has been convincingly formulated in the book “Transforming e-Knowledge” (Norris, Mason, and
Lefrère, 2002), where it is stated that:
In the Knowledge Economy, those individuals and enterprises that share and process their knowledge
effectively have a great advantage. To keep up, most of us will need a quantum leap in our ability to
manage knowledge. This won’t happen without a genuine transformation in the ways in which we
appraise what we know, what we can do with it, and what we need to know. […] Through this
transformation, learning and knowledge management will be fused in both theory and practice. This
synthesis will form the core of a new social and economic system based on knowledge sharing. This
transformation is underway. Participation in shaping the transformation is mandatory for all hoping to
achieve success in the Knowledge Economy.

However, although the utility-oriented knowledge economy is strategically important for our future, we cannot
afford to neglect the catharsis-oriented knowledge philosophy if the quality of the overall learning process is to
be maintained and improved. The great strategic challenge, upon which our future on this planet depends, is to
transcend these opposing knowledge perspectives and achieve a dialectical synthesis between the selfish and
unselfish views of knowledge.
