I released the 19th version of the GRDDDL profile and transformation for RDFa. The latest version of this profile and this transformation are always available at this URL:
The use of this profile licenses RDF data extracted by the RDFa2RDFXML.xsl XSLT transformation from an RDFa source.
If you want to declare that a document contains RDFa and always uses the latest profile, add this profile to the head of your XHTML:
If you want to use a specific version of the transformation, use the specific profile of that version, e.g.:
or reference the transformation directly, e.g.:
<link rel="transformation" href="http://ns.inria.fr/grddl/rdfa/2008/08/07/RDFa2RDFXML.xsl"/>
