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).
>> Eric argued a really interesting point. 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.
