Quite - let W3C staff handle namespace URI formats :)

But here I sense a possible problem.  Why do we need a different namespace for 
the ontology and DM, when they are essentially descriptions of the same 
things/concetps?  (There may be some additional "glue" URIs in the ontology, but 
I'd expect everything (or almost everything) identified as part of the DM to be 
formally described in the ontology.)

The problem here is illustrated by the very existence of this agendum in the 
recent OWL group discussions: 
http://www.w3.org/2011/prov/wiki/PIL_OWL_Ontology_Meeting_2011-10-17#Adding_missing_PROV-DM_terms_to_PROV-O 
  (thanks for the notes guys!)
