How is mnot going to figure out what those semantics are to generate a proper link-type header? Will all microformats be added to the IETF link-type registry? I've read over this thread a few times, and I still haven't seen any technical argument against the way RDFa handles @rel that is consistent with specs prior to RDFa. We have an example with GRDDL (and also with eRDF, though it's not a w3c spec) that @profile may define an *indirect* way, using other elements and attributes, to interpret @rel. RDFa is no different. Julian argues that GRDDL is not about interpreting @rel, it's just about extracting RDF/XML. I don't see the difference, but if one wants to draw a line, then simply put RDFa on the GRDDL side and assume that it's "just a way to extract RDF/XML." I think you'd be missing out on how much you can get out of RDFa, but certainly if GRDDL gets a pass on this, then RDFa should, too. In fact, remember that RDFa also specifies @about so you can, for example, have multiple images each with its own unique copyright license. For link-type to do the right thing, it actually needs to fully parse the RDFa. I'd be excited to have the link-type spec do that, but I doubt that's within its scope. So maybe ignoring RDFa is the right approach for link-type. -Ben
