I think there are two separate questions here... one is about RDF and one is about XML. Although RDF can be serialized in XML, the sorts of queries people are doing today with RDF query languages are over the abstract graph, not over the XML representation. For XML documents, and resources that present themselves as XML, one might reasonably consider using XML Query. It turns out there are lots of fairly complex things one might reasonably want to ask about the contents of XML Documents, so perhaps it's not surprising that XML Query is a rather large specification. I wouldn't expect all DAV implementations to support it, even in XML environments. So maybe this is an area where technical experimentation is needed before any standardization is considered. We could go to the XML Query Working Group and see if there is consensus on any such technical work; my personal expectation is that they are too busy right now to focus on such issues, just because of where they are in their editing cycle, but that this may well change by January. I can't comment on the RDF aspects. best, Liam Quin, XML Activity Lead, W3C -- Liam Quin, W3C XML Activity Lead, liam at w3.org, http://www.w3.org/People/Quin/ http://www.holoweb.net/~liam/
