Hi again!

To complete my proposal from earlier this day, I have now added to the
RDF-Based Semantics my proposal for the list of axiomatic triples, which I
have talked about in the last TC:


The first two "blocks" on "CLASSES" and "PROPERTIES" are exactly what I have
earlier proposed as the content of the owl2.owl ontology. It covers all the
OWL 2 classes and properties, and in addition the four annotation properties
from RDFS. So, by this means, owl2.owl would be represented in one of our
OWL 2 documents, and would have the same state as in OWL 1: There, it was
/informative/ and was contained in an appendix (in the Reference document).
The nice thing here is that it perfectly matches the given place in the
RDF-Based Semantics, it's not simply an "add on".

In addition, there are three further blocks on "DATATYPES", "FACETS" and on
of relevance for that section on "Axiomatic Triples" in the RDF-Based
Semantics. The third block covers all the 30+ mandatory datatypes of OWL 2.
The fourth block covers the facets (as datatype properties). The triples in
these two blocks correspond to what's written in the texts of Section 5.2
and 5.3 of the RDF-Based Semantics, respectively. The fifth block contains
the triples that make several OWL terms equivalent to terms from RDF(S):
e.g. owl:ObjectProperty is equivalent to rdf:Property in the OWL 2 RDF-Based

@Ivan: Can you please have a closer look to this list, maybe checking with
what's in your implementation? I could do this myself, but it's better to
have a second pair of eyes on this large list.
