RDFa est un projet du W3C pour rajouer des attributs sémantiques à XHTML, un concurrent aux microformats. "RDFa is a set of extensions to XHTML being proposed by W3C. RDFa uses attributes from XHTML's meta and link elements, and generalises them so that they are usable on all elements. This allows you to annotate XHTML markup with semantics. A simple mapping is defined so that RDF triples may be extracted."
