I think there are two aspects related to semantics.
One is interpretation (like: the world is flat by Mark). And this is in the ontology or, if you want, even in queries.
But there is also the fact that you "name" things when you expose a resource. The resource itself, or some info in more detail.
This naming is based on some common grounding without which you cannot apply ontologies or queries.

my 0.1 cents

That others could justifiably argue that the author's own RDF/OWL graph is incomplete, or flawed, or irrelevant, or even incorrect. And the same is true of any subsequent interpreters (i.e. authors of RDF/OWL graphs that purport to represent the "meaning" of the same document).

He argued (and Eric, correct me if I'm interpreting you wrong here), that semantics instead come into existence (or perhaps *can* come into existence) at the point when somebody executes a SPARQL query on a set of RDF/OWL graphs. That is to say, maybe I'm wrong and semantics doesn't even come into existence when somebody attributes an RDF/XML graph to a document; but rather it only comes into existence when somebody queries across (possibly) many graphs of many different people.
