XSPARQL
Homepage:
Description:
With currently available tools and languages, translating between an existing XML format and RDF is a tedious and error-prone task. The importance of this problem is acknowledged by the W3C GRDDL working group who faces the issue of extracting RDF data out of existing HTML or XML files, as well as by the Web service community around SAWSDL, who need to perform lowering and lifting between RDF data from a semantic client and XML messages for a Web service. However, at the moment, both these groups rely solely on XSLT transformations between RDF/XML and the respective other XML format at hand. In this report, we propose a more natural approach for such transformations based on merging XQuery and SPARQL into the novel language XSPARQL. We demonstrate that XSPARQL provides concise and intuitive solutions for mapping between XML and RDF in either direction, addressing both the use cases of GRDDL and SAWSDL. We also provide and describe an initial implementation of an XSPARQL engine, available for user evaluation.
Drupal Semantics
Homepage:
Description:
One of the key requirements for the Semantic Web to take off is the ability to express local content and its associated data model with existing well-known ontologies such as DC, FOAF, SIOC etc. RDF data with a local RDF schema that doesn't have any references to other schema is not very useful. We will present the latest developments in terms of RDF support in Drupal and in particular the modules RDF vocabulary importer and RDF CCK which when combined allow to map local content models to external vocabularies and export a mapped local schema and RDF data. Existing sites using the CCK module can simply install these modules and get a default local RDF schema for free. They can also map their local CCK fields to external RDF terms from any ontology available online. If time permits, we will also talk about Neologism which allows to create and publish custom vocabularies inline with the RDF vocabulary best practices.
Science Collaboration Framework
Homepage:
Acronym:
SCF
Description:
The Scientific Collaboration Framework (SCF) is reusable software that can be used to develop web-based, collaborative, scientific communities. The framework is designed to support interdisciplinary scientists in publishing, annotating, sharing and discussing content such as articles, perspectives, interviews and news items, as well as assert personal biographies and research interests – the basics of any online community. These web materials can then be linked to external, heterogeneous knowledge repositories of life science resources such as genes, antibodies, cell-lines or model organisms. SCF, thus supports structured “Web 2.0” style community discourse amongst researchers, makes various data resources available to the collaborating scientist and captures the semantics of the relationship among the discourse and resources.
YARS
Homepage:
Description:
YARS is a data store for RDF in Java and allows for querying RDF based on a declarative query language, which offers a somewhat higher abstraction layer than the APIs of RDF toolkits such as Jena or Redland. YARS uses Notation3 as a way of encoding facts and queries.
The interface for interacting with YARS is plain HTTP (GET, PUT, and DELETE) and is built upon the REST principle.
Much more information can be found on the YARS wiki.
The main requirement for YARS is to enable fast storage and retrieval of large amounts of RDF (in the order of millions of triples) while keeping a small footprint and a lightweight architecture approach.
inContext
Homepage:
Description:
The development and application of knowledge in the modern world necessarily involves the employment of increasing numbers of Knowledge Workers. These key people increasingly operate in new kinds of organisational structures and work patterns that require a large amount of inter-organisational activity in terms of technology and communication. Their work interaction patterns require highly dynamic forms of effective team collaboration/communication, which we have classified as ranging from Nimble (short-lived) to Virtual and Mobile/Nomadic Teams.
There is a considerable amount of flexibility in these activities. Teams transform themselves from one kind of organizational structure to another – indeed, in most cases, workers engage in many such teams simultaneously.
This pattern of working demand creates a requirement for support from adequate collaborative software services. To meet the requirements of dynamic, multiform team working, current Internet-based Collaboration Working Environments must evolve towards large-scale, loosely-coupled, trusted service-oriented systems of effective team collaboration, with increased emphasis on P2P collaborative software capabilities.
Drupal
Homepage:
Description:
Drupal is a free software package that allows an individual or a community of users to easily publish, manage and organize a wide variety of content on a website. Tens of thousands of people and organizations are using Drupal to power scores of different web sites.
