Eric,

In

   http://lists.w3.org/Archives/Public/www-rdf-interest/2000Jan/0050.html

you raised an issue with the RDF model and syntax spec which was recorded in

   http://www.w3.org/2000/03/rdf-tracking/#rdf-equivalent-uris

as

   Given web principles, there can in general be no centralised authority
   which defines the 'correct' URI for any given entity. Should the core RDF
   specs define a property that specifies two resources to be equivalent?

On 9th November 2001, as recorded in

   http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Nov/0294.html

the RDFCore WG resolved

   Whilst the WG recognises the importance of a mechanism for
   defining equivalence of URI's, the WG has decided it does not
   fit within the scope of its current charter.  The WG notes that
   DAML+OIL has an equivalence mechanism which raises the question
   of which layer of the stack best suits such functionality.  The
   WG also notes that by allowing cycles in rdfs:subPropertyOf and
   rdfs:subClassOf RDF Schema provides a related mechanism for
   properties and classes. Consideration of this issue will be
   postponed.

This issue will hopefully be given further consideration by a future WG with a 
more liberal charter.

If you have any comments on this decision, please reply to this message, copying
