W3C Invites Implementations of Timed Text (TT) Authoring Format 1.0 - Distribution Format Exchange Profile (DFXP)

2009-09-24: The Timed Text Working Group invites implementation of the Candidate Recommendation of Timed Text (TT) Authoring Format 1.0 - Distribution Format Exchange Profile (DFXP), used to represent timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information. The specification provides a standardized representation of a particular subset of textual information with which stylistic, layout, and timing semantics are associated by an author or an authoring system for the purpose of interchange and potential presentation.

New W3C Group to Standardize Relational Database, RDF Mapping

2009-09-16: W3C announces today the new RDB2RDF Working Group, whose mission is to standardize a language for mapping relational data and relational database schemas into RDF and OWL, tentatively called the RDB2RDF Mapping Language, R2RML. From the beginning of the deployment of the Semantic Web there has been increasing interest in mapping relational data to the Semantic Web. This is to allow relational data to be combined with other data on the Web, to link semantics directly to relational data and to aid in enterprise data integration. The creation of this Working Group follows the work of a previous W3C Incubator Group in this area. Read the RDB2RDF Working Group Charter and learn more about the Semantic Web.

W3C Invites Implementations of WebCGM 2.1
