I would suggest that the RDF WG look at Part 3 "Determining Resource
Identity" of "Resource Identity and Semantic Extensions: Making Sense of
Ambiguity":
http://dbooth.org/2010/ambiguity/paper.html#part3
That section proposes a standard process for determining resource
identity.  As far as I know, I did not invent this process.  I simply
documented what seemed to be the general ideas floating around. 

However, I did identify one specific gap in the RDF specs:
[[
At present there is a minor gap in the RDF standards, in that there is
no standard way for an RDF processor to recognize that a particular URI
is intended to signal an opaque semantic extension: the knowledge of
which URIs are intended to signal opaque semantic extensions must be
externally supplied to the RDF processor.  The RDF processor must
magically know about them in advance.  It cannot alert the user to the
need for a new opaque semantic extension that was previously unknown.
This gap could be addressed by defining a standard predicate, such as
rdf2:requires, to explicitly indicate when a particular semantic
extension is required.  However, since it currently seems unlikely that
many semantic extensions will be needed that cannot be defined using
standard inference rules, this does not seem like a major gap.
]]

I will forward this message separately to the RDF comments list, since I
cannot post to the regular RDF list.
