Yes, thanks. Changed to "... OWL 2" there.

Yes, this resulted in a few minor changes.

Having a more distinguishing name instead of just "vocabulary" is a good idea, IMO,
in order to avoid, e.g., confusion with the vocabularies of the Functional Syntax
or the OWL/XML syntax. I can see, however, a few slight issues with the concrete 
suggestion "RDF-graph vocabulary". 

First, I would then like to generally call the vocabularies of other RDF semantics 
in the way "XXX RDF-graph vocabulary" as well. But this would sound strange for 
XXX := "RDF(S)".

So I thought "graph vocabulary" might be good. But then, I remembered that the RDF Semantics
(in Section 0.3) already talks about a "vocabulary of a graph" (in contrast to a vocabulary
of an interpretation), and I have called this a "graph vocabulary" myself several times
in the past.

But, after all, isn't the most distinguishing aspect of the RDF/RDFS/OWL 1/2 vocabularies 
that they consist of URI/IRIs? They don't have much to do with RDF graphs. So why not 
simply call them "IRI vocabularies"? This seems to at least avoid confusion with our
other syntaxes.

>If the sentence above was then removed from the Introduction

Agreed, this was a strange beast, anyway, so it's good to have it removed.

(I filled the gap with a sentence mentioning datatypes and facets, 
which are also treated in the "Vocabulary" section.)

Removed!

Ok, here is the complete diff:

  <http://www.w3.org/2007/OWL/wiki/index.php?title=RDF-Based_Semantics&diff=21795&oldid=21756>

It's a lot, but the three most interesting changes are those in the Introduction (§1), in Section 2.1, and in the "Changes" section (§9). In all cases, I basically reused the formulation from the Document Overview of the form "RDF graph interpreted using the RDF-Based Semantics" (in slight variants) for referring to "OWL 2 Full". 

Is this ok? Then we (I?) can adjust the "Conformance" document accordingly, and afterwards we seem to be ready to go.
