Last Call: RDFa Core 1.1, XHTML+RDFa 1.1

The RDFa Working Group has published Last Call Working Drafts of RDFa Core 1.1 and XHTML+RDFa 1.1. The current Web is primarily made up of an enormous number of documents that have been created using HTML. These documents contain significant amounts of structured data, which is largely unavailable to tools and applications. When publishers can express this data more completely, 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.

RDFa Core is a specification for attributes to express structured data in any markup language. XHTML+RDFa 1.1 is one such language; it is a superset of XHTML 1.1 intended for authors who want to create XHTML Family documents that embed rich semantic markup. There was a very wide review of the First Last Call for RDFa 1.1 by key members of various standards communities, large companies and independent Web developer communities. Due to the large amount of solid feedback by the various respondents, numerous improvements and enhancements were made to RDFa 1.1 to reflect the desires of the developer community.
