N.B. In the most common scenario, y is the owner of x.  
this general mechanism is already implemented and the thing I know best 
is uriqa

jup, so let us standardize uriqa or something else.

alas, standardization is always a tough thing to do, all these boring 
documents to write, etc.
DanB once said to me that the dublin core work was hard and tough work 
while making foaf was a joyful experience.
So standardization could work like it is now: we see that it works,
we hack code.
it spreads.

Uriqa does most of the stuff we need and anything else would probably go 
deeper to URI CRISIS

one uri, ie a picture uri like
may be described by RDF like

tada,, it works.
but the semantics behind is tough: parse for a "." in the uri and 
replace it by ".rdf"
that does not work in general, we had the discussion already years ago.

so the MGET/ GET approach by URIQA in combination with known webservices
at /uriqa? is a very good thing to start.
If mget fails, add a config string with the uriqa service uri and you 
are done.

We used this to connect mindraider.sf.net to www.gnowsis.org
was a one day hack, done without much programmer communication,
as the standard is easy.
