Re: parent <-> subject etc

Guys - I am going to trust Hilmar's judgement at the end of the day about
when the Ontology stuff is ready to go on the branch and i can release.
Hilmar - give me the all clear.


I'd also like to say that I think Chris' experience about
subject,object,predicate is probably well worth listening to. Requires all
of us to get used to it, but clearly it is far, far less ambiguous.
