I just want to bump the thread because of some new work that is going on at ping.semanticweb.org [1] which I find highly relevant to the RDFa work. I was suggesting to Uldis Bojars that we should add RDFa support to his Semantic Radar Firefox extension [2] as well as to the ping service. However, we can't just ping the service with *every* XHTML page so I'm thinking we will need something like a profile or link/@rel pointer to indicate that there's RDFa in XHTML besides changing namespace documents at w3.org.
