I'm going working on the PR version of  Reference. The owl.rdf file 
currently contains the following "ontology header":

[[
<Ontology rdf:about="">
   <imports rdf:resource="http://www.w3.org/2000/01/rdf-schema"/>
   <rdfs:seeAlso rdf:resource="http://www.w3.org/2001/sw/WebOnt/" />
   <rdfs:seeAlso rdf:resource="http://www.w3.org/TR/owl-features/" />
   <rdfs:seeAlso 
rdf:resource="http://www.w3.org/TR/2003/CR-owl-test-20030818/" />
   <rdfs:seeAlso 
rdf:resource="http://www.w3.org/TR/2003/CR-owl-semantics-20030818/" />
   <rdfs:comment>This file specifies in RDF Schema format the
     built-in classes and properties that together form the basis of
     the RDF/XML syntax of OWL Full, OWL DL and OWL Lite.
     We do not expect people to import this file
     explicitly into their ontology. People that do import this file
     should expect their ontology to be an OWL Full ontology.
   </rdfs:comment>
   <rdfs:comment>$Id: owl.rdf,v 1.5 2003/08/19 15:07:19 connolly Exp 
$</rdfs:comment>
   <versionInfo>$Id: owl.rdf,v 1.5 2003/08/19 15:07:19 connolly Exp 
$</versionInfo>
</Ontology>
]]

[Note: Appendix B is actually different, not sure how that happened]

I propose to revise/simplify this to:

[[
<Ontology rdf:about="">
   <imports rdf:resource="http://www.w3.org/2000/01/rdf-schema"/>
   <rdfs:isDefinedBy rdf:resource="http://www.w3.org/2001/sw/WebOnt/" />
   <rdfs:comment>This file specifies in RDF Schema format the
     built-in classes and properties that together form the basis of
     the RDF/XML syntax of OWL Full, OWL DL and OWL Lite.
     We do not expect people to import this file
     explicitly into their ontology. People that do import this file
     should expect their ontology to be an OWL Full ontology.
   </rdfs:comment>
   <versionInfo>$Id: owl.rdf,v 1.5 2003/08/19 15:07:19 connolly Exp 
$</versionInfo>
</Ontology>
]]

where the "versionInfo" gets appropriately updated.

Rationale:
- pointer to WG home page should be sufficient
- versionInfo is the appropriate slot for the cvs info

This incorporates a suggestion from Dave Beckett [1] to change 
rdfs:seeAlso to rdfs:isDefinedBy. I remember some problems with the 
latter option, but cannot recollect the details. Any thoughts?
