(I thought I had seen a sentence from Peter on the NP complete problem, that 
should go in here appropriately too, but I can't find it right now)


Dear Brian,
concerning the comments of RDF Core in
http://lists.w3.org/Archives/Public/public-webont-comments/2003May/0052.html

> owlsas-rdfcore-np-complete

We have accepted this comment and made appropriate changes to eliminate the 
embedding of the Hamiltonian Path problem.

> owlsas-rdfcore-bnodes-restrictions

We agree that there may be cause for concern, but note that the changes 
requested would minimally require a major rework of the direct semantics of 
OWL DL. (Section 3 of S&AS).

We have created a new issue and postponed it, so that a future group may, with 
the benefit of deployment experience, assess whether these concerns were 
legitimate, and whether the quantity of work required to attempt to address 
this issue is motivated.

We are still considering relaxing some of the constraints on bnodes 
corresponding to class expressions; however, this does not seem to be your 
main concern. We will notify you of any change.

Please reply to www-rdf-comments to indicate if these responses are 
acceptable.
