Future Directions and Advanced Technologies
The widespread usage of XML in the last few years has resulted in the development of a number of XML query languages like XSLT or the later developed XQuery language. Today, there are many products like databases in the area of XML processing that support either XSLT or XQuery, but not both of them. This may prevent users from employing their favourite XML query language. In this chapter, the authors show that both languages have comparable expression power and present a scheme for translating XQuery to XSLT and vice versa. This translation scheme enables a user to employ either XSLT or XQuery for each product which supports one of these languages. They also summarize in this chapter both current and future trends and research issues and also consider those that might emerge in the common area of XSLT and XQuery and which are particular to XSLT.
XML (eXtensible Markup Language) transformations and queries are crucial operations for interpreting XML databases. XSLT (eXtensible Stylesheet Language Transformations) is a prominent XML technology for these operations, but XQuery (XML Query Language) can query a broad spectrum of XML information sources, including both databases and documents. In this paper, we present our approach to translate XSLT to XQuery. We illustrate our approach as a set of rules or templates which translates an XSLT document into XQuery. We also discuss grouping operations for both XSLT and XQuery. Finally, we present the performance of XSLT versus equivalently transformed XQuery documents for varying sizes of documents and for different rules.

XML is becoming the most relevant new standard for data representation and exchange on the WWW. Novel languages for extracting and restructuring the XML content have been proposed, some in the tradition of database query languages (i.e. SQL, OQL), others more closely inspired by XML. No standard for XML query language has yet been decided, but the discussion is ongoing within the World Wide Web Consortium and within many academic institutions and Internet-related major companies. We present a comparison of five, representative query languages for XML, highlighting their common features and differences.

As more and more information is either stored in XML, exchanged in XML, or presented as XML through various interfaces, the ability to intelligently query our XML data sources becomes increasingly important. XML documents are structured documents – they blur the distinction between data and documents, allowing documents to be treated as data sources, and traditional data sources to be treated as documents. XQL is a query language designed specifically for XML. In the same sense that SQL is a query language for for relational tables and OQL is a query language for objects stored in an object database, XQL is a query language for XML documents. The basic constructs of XQL correspond directly to the basic structures of XML, and XQL is closely related to XPath, the common locator syntax used by XSL and XPointers. Since queries, transformation patterns, and links are all based on patterns in structures found in possible XML documents, a common model for the pattern language used in these...
Entre pantallas y realidades: una travesía por el universo audiovisual, 2024
Los videojuegos son productos culturales frutos de la realidad del momento, se inspiran en ella para representarla en mundos ficcionales. La credibilidad del periodismo está en entredicho, una confianza en los medios que hasta los propios periodistas llegan a cuestionar, a raíz de prácticas como la publicación de noticias falsas y la falta de fuentes oficiales y del contraste de la información. El objetivo de esta investigación es comprobar cómo a través de los newsgames o videojuegos que sirven para contar la actualidad se puede reflejar la profesión periodística. A través de la ludonarrativa, se ha realizado un estudio de caso sobre el título Headliner: Novinews (Unbound Creations, 2018) al que se le han analizado aspectos como las mecánicas, los temas presentes, las dinámicas periodísticas y la estructura narrativa. Los resultados ponen de manifiesto que los intereses políticos y empresariales que afectan a los periodistas en su trabajo aparecen en este desarrollo interactivo, mientras que el contenido periodístico que se decide publicar tiene un impacto variable en aspectos cotidianos como la economía, la política y la salud, en función de la rigurosidad profesional. Headliner: Novinews es por tanto una buena herramienta de alfabetización mediática para comprender el periodismo actual.
