Looks like ppl are reading more into this discussion than I intended.
The hypergrid is up & running with all authentication and security in
place, and so are exchanges of content via HG and archives. What's
missing is *systematic* global identification of resources. OpenSim
already does that internally for resolving *certain* identifiers on the
Hypergrid, but nothing is stored persistently yet. That is going to
change soon, because 1) I want to make friends & IM work across the HG
(so, for example, your foreign friend needs to be identified by a global
ID); and 2) we really need to fix the b0rked "creator" field in OARs/IARs.
This means that we need to write URIs persistently, both in certain
fields of the DB (which is already prepared for what's coming) and in
the archives.
So the issue here is really narrow. Assuming everyone agrees that we
should use URIs, should we add type information in the URI or not? Any
other thoughts on the *form* of these URIs?

May be good to share what your use case is. As universal are you suggesting
an identifier that separate, potentially un-trusted domains, would use to
identify the same person?
Is so I don't think you can do that with two parties, you need at least one
more party to validate that they are the same person, like how we do with
SSL certificates, or with some kind of authentication, like you send me an
email address which gets me to a profile, but I still need to enter in a
password or something to get access to that profile.

A couple of thoughts and observations Diva...
Could the taxonomy of "types" you use cause problems if the chosen
1-1 mapping for a UUID is not felt to work well i future.
"user" is also perhaps a different notion to a specific "avatar"
It would be nice if any UUID in a URI you use can be resolved (e.g.
to the avatar name) by any host that has the mapping (like the
distributed nature of DNS works), so its not dependent on the host
continuing to exist, or to be up at the time information on the
avatar is sought.
AS an example, we have shifted our data bases between machines and
have done so 3 or 4 times since we started running OpenSim, carrying
the UUIDs of avatars (and the UIIDs of regions we use) forwards to
the new data bases.
