Okay then, you are comparing apples to oranges.  Saying RDF
'identifies' things is an abuse of notation as far as I'm concerned.
RDF denotes 'things' (the mechanics for this are very well-defined -
/TR/rdf-mt ), web-arch "identifies".  These are not equivalent
mechanisms, or at least their definitions do not correspond.  If *we*
are serious about consistency between 'classic' web architecture and
the semantic web, we need to fix this disconnect *before* suggesting
best practices prematurely.

Yes, I gathered this from Dan's follow-up response about the HTML RFC
being the source of the 'problem'.  Still, the ambiguity you are
speaking about is between two completely orthogonal mechanisms for
reference ("identification" versus denotation).

Frankly (and this has been my perpetual theme), if there is serious
concern about ambiguity, then a language well-equipped to handle
ambiguity should be used.  A vacuous notion of "identification" is
simply not sufficient.

See above.
