agree, good thinking re @vocab too! We could define Absolute-URI pointing to [1] absolute-URI = scheme ":" hier-part [ "?" query ] [1] http://tools.ietf.org/html/rfc3986#section-4.3 We actually may have an issue around this, that may be worth raising (if you agree I can raise it) - because currently we use the phrase "AbsURI" (e.g. TERMorCURIEorAbsURI) through the spec to refer to a "URI" (not an absolute uri), and now it seems need to define a real AbsURI. I'd be happy to detail the issue and run through the spec pointing to the areas where things are ambiguous, with proposed text to clear up the issue.

That is the only URI that an RDFa processor will dereference, and two different URI-s differing by a fragid only will return the same graph. On the other hand, using two different URI-s for the same graph my make the local caching process inefficient (unless clients would strip the fragid part before caching but I would not expect them to do that...) >> Hmm, should we be clarifying the definition of @profile to accept a whitespace separated list of absolute-URIs (never relative, never with fragment) to avoid /some/ unexpected behaviour? >> >> * I say some, because people could still use "mailto:bob@example.org", but I figure we shouldn't cater for people who like to do things like that! >> >> Best, >> >> Nathan >> >>>>>> ISSUE-84 > > > ---- > Ivan Herman, W3C Semantic Web Activity Lead > Home: http://www.w3.org/People/Ivan/ > mobile: +31-641044153 > PGP Key: http://www.ivan-herman.net/pgpkey.html > FOAF: http://www.ivan-herman.net/foaf.rdf > > > > >
