The RDFa Working Group has just published two Working Drafts: RDFa Core 1.1 and XHTML+RDFa 1.1. RDFa Core 1.1 is a specification for attributes to express structured data in any markup language. The embedded data already available in the markup language (e.g., XHTML) is reused by the RDFa markup, so that publishers don’t need to repeat significant data in the document content. XHTML+RDFa 1.1 is an XHTML family markup language. That extends the XHTML 1.1 markup language with the attributes defined in RDFa Core 1.1. This document is intended for authors who want to create XHTML-Family documents that embed rich semantic markup.
