[Opensim-dev] Global identifiers

[diva at metaverseink.com]

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?
