Thanks for the answer. Yes it is quite quite intresting to open the
discussion on the two issues. 

My understanding is that only if you have in mind the whole picture of
the RDF/S specifications you may arrive to useful design choices.
Furthermore, up to know most of the choices are based on the open
world assumption. However, I din't see any useful reasoning service
defined on top. On the contrary I have seen a lost of useful services
(validation, efficient storage, query optimization) based on the
"closed world assuption".

It is quite disappointing that after 4 years of passionate discussions
on the open world assuption the only real systems that someone can use
and implement bits of the Semantic Web are based on the "closed world
assuption". This is quite scary!!!

Best

Vassilis
