It's the difference in identity as established by a
process handling a representation and existence of
the thing so identified.
It isn't difficult to understand. The thing only
has identity in the sense that the system has a
unique id. The system has the property of uniqueness,
not the thing. There is no way out of this, but you
don't need one. ALL you are talking about is a system
object, not the person. It is a red herring until someone
asserts the two are equivalent.

I don't understand this -- why is it not possible to identify a person
in an RDF sense? A URN is just a name; just like "John Cowan" and
"mailto:email@example.com" are adequate ways to identify you for
anyone on the mailing list who wants to refer to you.
