I completely agree with Peter here. 

I've read the relevant documents on the RDF side and I am in quite a state 
of shock.  This has NOTHING TO DO with OWL, (or with RDF for that matter). 
 You simply can not, as a matter of course, define as part of a language 
how much responsibility people have for what they say in that language. 
That is not the role of technology, nor of standards.  It is the role of 
law.  The W3C is not a law-making body, not in the US nor anywhere else in 
the world.

I find that the risks of incorporating any and all social meaning into the
official meaning of RDF and OWL document to be unacceptable to me.  I
believe that they will be unacceptable to Lucent as well, and also to just
about any legal entity.

Note that the impact of social meaning is that any RDF document that
uses a URIref includes the entirety of the social meaning of any document
that can be found by dereferencing the URIref.   See Section 4.5 of the 
RDF
Concepts document for a particularly informative example.
