w3.org news: Last Call: RDFa in XHTML: Syntax and Processing

2008-02-21: The Semantic Web Deployment Working Group and the XHTML 2 Working Group have published the Last Call Working Draft of RDFa in XHTML: Syntax and Processing. RDFa is a specification for attributes to be used with languages such as HTML and XHTML to express structured data. When publishers can express structured data, and when tools can read it, a new world of user functionality becomes available, letting users transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience. For example, a photo's creator, camera setting information, resolution, location and topic can be published as easily as the original photo itself, enabling structured search and sharing. With RDFa, the rendered, hypertext data of XHTML is reused, so that publishers don't need to repeat significant data in the document content. The RDFa specification explains use of the RDFa attributes with XHTML. Comments are welcome through 21 March. Learn more about XHTML and the Semantic Web Activity. (Permalink)
