The RDF Web Applications Working Group has published RDFa Core 1.1, RDFa Lite 1.1, and XHTML+RDFa 1.1 as W3C Recommendations. The group also published the RDFa 1.1 Primer as a Working Note. Together, these documents outline the vision for RDFa in a variety of XML and HTML-based Web markup languages. RDFa Core 1.1 specifies the core syntax and processing rules for RDFa 1.1 and how the language is intended to be used in XML documents. RDFa Lite 1.1 provides a simple subset of RDFa for novice web authors. XHTML+RDFa 1.1 specifies the usage of RDFa in the XHTML markup language.
