Jeff,

Would it be possible to post a list of need to know links for these to the
list? Links to the WDs and relevant mailing lists would be great...

Thanks,

sure:

1) RDF Semantics http://www.w3.org/TR/rdf-mt/

    I think this is a very well written document and surprisingly
approachable for a "model theoretic semantics" -- contrast to the OWL
Semantics which is far more technical

In particular read
0.2 Graph syntax . http://www.w3.org/TR/rdf-mt/#graphsyntax

and

1.2 Urirefs, resources and literals. http://www.w3.org/TR/rdf-mt/#urisandlit

2) RDF Concepts and Abstract Syntax http://www.w3.org/TR/rdf-concepts/

    (I prefer the RDF Semantics myself).

3) OWL Guide -- http://www.w3.org/TR/owl-guide/ -- This is a good intro to
ontologies (IMHO)
4) OWL Reference -- http://www.w3.org/TR/owl-ref/
5) OWL Features -- http://www.w3.org/TR/owl-features/ -- a bit dated and
soon to be updated
6) OWL Semantics -- http://www.w3.org/TR/owl-semantics/ -- a bit technical,
defines the abstract syntax (productions) for a non-RDF OWL language that
may be transformed into RDF/XML. A non-RDF XML Schema for OWL is in the
works (soon to be published).

I've left some out, but this is a good start.
