I did of course mean to use "&" between the key-value pairs, not ",".

Diva I think is suggesting optional extra data beyond the grid name 
and UUID, melanie I believe is suggesting anything added is 
compulsory, and that the avatar display name is in that class (as I 
think most people have also agreed) .

Either way, things and requirements can change, and there could 
therefore be different "versions" of such URIs with and without some 
later field.  Hence my suggestion that it uses a flexible format 
of  key=value pairs and that we make clear what is expected or 
required for any given resource_type, , and what is for helpful 
additional information.

protocol://authority/resource_type/resource_id?key=value&...

Perhaps a bit more radical.... I even wonder if the resource_id 
(and  resource_type?) should be the same (i.e. all key=value 
pairs).  That way all sorts of CGI and web app lookups would be 
possible without web server URL mapping.

protocol://authority/resource_type/?resource_uuid=UUID&key=value&...

protocol://authority/<root>?resource_type=type&resource_uuid=UUID&key=value&...

I assume some sensible <root> part of the URI would be needed and 
others have noted that might help to differentiate incoming service 
calls for this functionality on the web server component of the 
OpenSim HTTP listener.  E.g. <root> = id

While not wanting to open this up even more... hey why not.. its a 
good discussion...  it would seem that we are wanting a URN 
(Universal Resource NAME) as we do not want to imply availability of 
the identity/"name" at a given location. But I think Karen has 
already been talking along these lines.
