Have you heard back from the Dublin > Core decision-making authorities? > http://lists.w3.org/Archives/Public/public-html/2010Jan/0576.html There was a little discussion on the Dublin Core Advisory Board list (not a public forum; sorry no links). I don't believe we considered explicitly the scenario in which profile= gets lost, but something like RDFa is not permitted for HTML5. Maybe Pete or Tom (cc:'d) can comment further? My personal guess at a DC view would be something like "well if we don't get RDFa, then don't take @profile away!", the assumption being that RDFa would come with some namespace abbreviation mechanism, whether xmlns:-based or otherwise. I doubt the DC community would be satisfied by the current Microdata design in which each use of a DC property would be identified by its full URI. If you like, I can ask explicitly. > The microformats community seems happy to explore alternatives. > http://lists.w3.org/Archives/Public/public-html/2010Feb/0690.html > > I'm considering pushing back on the 0794 proposal, but it's only > worth my time if somebody actually needs head/@profile to survive > into HTML 5. > > Does anybody need it? That's a little like asking if someone needs the emergency life-raft before telling them whether they get to keep using the boat or not. WIthout RDFa, DC would have to use it. > On a somewhat related topic... as RDFa matures, the need for GRDDL > somewhat fades.

I've never used GRDDL, and I don't know of anyone actively using it. That said, there are many things I don't know! I have tried to get Redland/Raptor working with it to consume POWDER a couple of times, but with no success. When I think about running GRDDL against wild Web content, I have some vague worry about whether untrusted XSLTs are sufficiently sandboxed, but I haven't investigated the risks very carefully. I remember Bijan raising similar concerns a while back. cheers, Dan > See also: > > The details of data in documents: GRDDL, profiles, and HTML5 > By Dan Connolly in HTML, Semantic Web, Web Architecture, XML on August > 22, 2008 7:45 PM > http://www.w3.org/QA/2008/08/the_details_of_data_in_documen.html > > -- > Dan Connolly, W3C http://www.w3.org/People/Connolly/ > gpg D3C2 887B 0F92 6005 C541 0875 0F91 96DE 6E52 C29E > >
