I'm surprised to hear you say that, Roy.  I believe that the Semantic
Web will care because one needs to be able to merge graphs without prior
knowledge of what's being merged.  If the target of an assertion varies
as a function of the definition of the predicate, that will not be

Though I can't find it right now, some time ago on www-tag you
suggested, IIRC, that the Semantic Web could use a function to
disambiguate between when the target of the assertion was the resource
vs. a representation of the resource.  I believe this is a superior
approach to what I interpret you to be suggesting above, as would any
other approach which added additional information to a triple to
license a recipient to determine what the target of the assertion was.
