Call for Review: SKOS Reference Proposed Recommendation

2009-06-15: The Semantic Web Deployment Working Group has published the Proposed Recommendation of SKOS Simple Knowledge Organization System Reference. SKOS provides a common data model for sharing and linking knowledge organization systems via the Web. SKOS is a vocabulary for expressing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading schemes, taxonomies, folksonomies, and other similar types of controlled vocabulary. As an application of the Resource Description Framework (RDF), SKOS allows concepts to be composed and published on the World Wide Web, linked with data on the Web and integrated into other concept schemes. Along with this publication of the SKOS Reference Proposed Recommendation the Working Group has published an updated SKOS Primer Working Draft. Comments are welcome through 15 July.

W3C Invites Implementation of OWL 2

2009-06-15: The OWL Working Group invites implementation of its OWL 2 Web Ontology Language. OWL 2 is a compatible extension to OWL 1, providing additional features for people using ontologies. An ontology is a structured set of terms that a particular community uses for organizing data, such as "title", "author", and "ISBN" for data about books. The OWL 2 document set contains 9 technical specifications and 4 instructional documents. The Recommendation-track specifications are now Candidate Recommendations, indicating that the Working Group and the W3C Director believe this is a good time for systems to begin adopting OWL 2 features on an experimental basis. The group maintains a list of implementations and encourages new information about implementations and other feedback to be sent to it comments address. The 4 instructional documents, which provide an introduction to OWL 2, are now at Last Call: overview, primer, new features and rationale, and quick reference. Finally, a new datatype used within both OWL and RIF, called rdf:PlainLiteral (formerly called rdf:text) is also a Candidate Recommendation. Learn more about the Semantic Web. (Permalink)

UK Government Moves to Put Data on the Web

2009-06-10: Today the Office of the Prime Minister in the UK announced that Tim Berners-Lee will "help drive opening of access to Government data on the web over the coming months." The announcement is an important step in helping to fulfill the vision for a Web of Linked Open Data built on W3C's open Semantic Web standards, espoused by Berners-Lee in his TED 2009 talk. "Government data the people's data is an important component to the larger Linked Open Data movement," said Berners-Lee. "I look forward to working with multiple government agencies and local enthusiasts to help early adopters bring their data to the bigger picture." In April, Berners-Lee engaged similarly with the US government offering to help them join the "rapidly growing Linked Open Data cloud, to which US recovery data will be a welcome addition." W3C's own eGovernment Interest Group has also been actively building an international network of support to work with governments on issues of transparency, accountability, and efficiency through open data.
