W3C Invites Comments on First Drafts of RDFa Core 1.1, XHTML+RDFa 1.1

The RDFa Working Group has published the First Public Working Drafts of RDFa Core 1.1 and XHTML+RDFa 1.1. RDFa Core is a specification for attributes to express structured data in any markup language. XHTML+RDFa 1.1 is an application of RDFa Core 1.1 for XHTML. Both of these documents are expected to supersede the RDFa in XHTML (RDFa 1.0) specification. Together, these specifications enable the human-readable and machine-readable markup of people, places, events, products, recipes, social networks, and many other concepts that are frequently published on the web. These documents improve upon RDFa 1.0 by adding a number of Web community requested features to ease authoring. Comments are welcome and should be sent to the public-rdfa-wg@w3.org mailing list (see also the archives).
