I think #a is misleading as written, because it suggests that a URI
either does or does not refer to a distinct thing, and IMO that is
wrong.  Whether a URI refers to a distinct thing depends on the graph
that is being considered, i.e., it depends on the *application*.  A URI
may be unambiguous to one application (using that URI in one graph), but
ambiguous to another (using that same URI in a different graph).  In
fact, in all but a vanishingly few cases, this will be the case.

I think what is needed in #a is to ensure that the semantic web
community agrees on a set of conventions for establishing and
determining resource identity for a given graph.  My writings at
are intended in this direction.

because there is a cost to making this distinction, and not all
applications need it.
