Pat you are confusing me.  I though TBL was saying that if anyone uses
a URI with  _my_ namespace prefix (example:
names:robustai.net/chiggy#foo), then they are asserting that they are
talking about the exact same thing that am talking about when I use
that URI.  It doesn't matter where in the Web they record their
message, or who records it. And the plan is for people to try to use
URIs from standard namespaces for our common public concepts as much
as possible.  Please, somebody, correct me if I am operating under a
misapprehension.  Pat, If this is true, wouldn't you have exactly what
you want?

I think this Semantic Web Plan works only in as much as we *do* use
common URIs; to the extent that everybody makes up their own URIs to
talk about their own private matters, we don't have a semantic web at
all; we would just have the tower of babble to which you refer.

If my assumptions are correct (sheeze i hope they are) this still
means that one will probably encounter many different URIs for the
same concept.   Pat, does this problem bear on your concerns?   The
only solution I see to that problem is for each local application of
the Semantic Web to install some kind of fuzzy node matcher that would
attempt to combine nodes that are really the same, based upon their
relationships to literals and other known nodes.  In combining nodes
the applications could preserve all the original URIs and the sources
from which they were originally read.  Then when the application wants
to speak RDF to those sources, they could use the URIs which that
source will recognize.  See my signature for an example.
