No, I still consider notion of URI declaration, and the distinction between core assertions and ancillary assertions, to be extremely relevant.  I think they help clarify what the Semantic Web architecture needs.

Descriptions linked from a Resource-Description header can allow the URI owner to provide useful assertions about the resource, even though they would be ancillary assertions rather than core assertions.  I thought that was what page
http://esw.w3.org/topic/FindingResourceDescriptions
was seeking.  However, I'm now wondering if by "Uniform Access to Descriptions" you really meant "uniform access to *core* assertions".  The key difference is that use of a URI only implies agreement with its *core* assertions -- not its ancillary assertions.  Which was your intent?  And if your intent was ancillary assertions, then why does it matter whether the URI owner provided them?
