Re: Namespaces

Kal,

You talk much sense as ever.

I see you've put a query after value - surely even if we drop beginsWith 
etc. value is needed for matches?

On the issue of allOf, oneOf etc. Eric P made a suggestion for how we could 
resolve this. Use the Owl unionOf etc. and put it through a generic OWL 
processor. If we got the desired result then it would be OK to use it. If 
not, we know that our own RDF definition was necessary.

But, my thought is that if we keep the allOf, oneOf and not classes then 
that would give people a choice of using those or OWL? Or am I being too 
woolly?

One thing I keep forgetting to bring up again is the issue of "contains one 
scene of", "contains several scenes of" and "frequent scenes of". I can see 
arguments for this being in namespace 1 but they probably belong in 2?

Phil.
