Another thing related to identity that people should know, and that
touches on what Dahlia is saying: identity does not belong to users; it
belongs to identity services, in principle, unless those identity
services say it otherwise in the TOS (but I can't really see how that
would work... after all, it would be impossible for Mr. Smith to
continue to use myworld.com/smith as identity after parting ways with
MyWorld due to the way DNS works). If you want to own your own identity,
then the best shot is to run your own identity service.
OpenSim is already prepared for the existence of identity services that
are independent of any specific grid. Meaning, there's an identity
service to which people login, but that sends the user's agents to
worlds out there, because it's not associated with any particular world.
Conceptually, that's how the current (HG) login service works. The best
combo at this point would be UserAccount+UserAgent+Inventory+Asset services
(the existence of inventory upon login is sort of mandatory with the LL
viewer)
Note to entrepreneurs: the opportunity is now here to start identity
service businesses for virtual worlds. I can see the tag line "Confused
about which world to sign on? Sign on with none! Get an identity with us!"

Would it be possible to use just the UUID part and not tie it to a
specific domain? I can foresee events where a user and a
business/grid/domain owner/whatever make a decision to go separate ways
and then any other systems out there that have the global identifier
referenced may not be able to use it to contact that user. If only the
UUID were used (we already use UUIDs for many diverse applications and
the context implies the specific usage) it could be similar to a cell
phone number where a user can take it from carrier to carrier. Resolving
the current user domain would need to be worked out but several methods
might be considered from a P2P network of resolvers to one or more
central authorities, and/or simply storing it in a cache in local
installations when the UUID is first used.
If we only use the UUID part then it may have some backward
compatibility with existing user UUIDs used to identify content creators.

I'm about to introduce global identifiers, so that I can make
friends and IM work on the hypergrid, and would like feedback on the
best form of these identifiers. Here are some options:
http://myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b
myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b
<http://myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b>

[email protected]:8002
<http://[email protected]:8002>
...
In this particular case (for friends and IM) we're dealing with user
accounts, but the issue is broader than that. Whatever form we
choose should be applicable to all sorts of resources.
My preference is to use a URI, according to the spec of URIs
(http://www.w3.org/Addressing/URL/uri-spec.html). The question is:
should we add additional specifications on these URIs? Like using
the path /user/ for user accounts, etc.
Thoughts?
Thanks.
