Why wouldn't I just use http://danbri.org/foo.html#danbri or anything similar for HTML fragments? (I'm assuming that foaf.rdf returns an application/rdf+xml documend, and foo.html returns an application/xhtml+xml document; the extensions may be meaningless to the protocol but help to keep things apart for humans and computers.) Also, I don't see much of a need to denote an RDF node per se. I'm sure there are special applications one can come up with where reasoning about RDF nodes per se is helpful/necessary/whatever, but for such cases, there are other techniques available already. A single special property and blank nodes would do the job. Regards, Martin. > When a URI owner uses content negotiation, they should make the content > of each representation consistent.
