Hi Julian, I had started last week to look at some of the issues around metadata in HTML 5 and the questions they seem to raise for DC-HTML, so I'd be happy to contribute to this, preferably with Dan and Andy's help.

Yes, that's a good idea. Currently, the DC_HTML profile makes use of a GRDDL profile transformation (an XSLT stylesheet), and that transform outputs RDF/XML. It should be relatively easy to create a similar transform which instead generates an XHTML+RDFa document (I see from your follow up you've already created one!). Incidentally - and this isn't really central to the issue at hand - this did raise a GRDDL question in my mind: currently, like every other GRDDL transform I've seen, the DC-HTML profile transform generates RDF/XML. But I'm not sure whether GRDDL requires a transform to generate RDF/XML output, or whether any XML syntax for RDF (e.g. XHTML+RDFa) is permitted. Pete
