RDFa (RDF in XHTML) Task Force Home

This is the workspace for RDFa (RDF in HTML). You may also want to subscribe to the mailing list of the RDF in XHTML Taskforce.

RDFa is a W3C Recommendation

On 14 October 2008 RDFa became a W3C Recommendation (a Web standard). See the full specification and the short primer. The source for the test harness is also available.

This work was started by the RDF-in-XHTML Task Force, a joint task force of the Semantic Web Deployment Working Group and the former (pre-2007) HTML Working Group. When the HTML work was rechartered in 2007, the task force became joint work between the XHTML2 Working Group and the SWD WG.
