[Opensim-dev] Global identifiers

[diva at metaverseink.com]

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/user/7c4450fc-aeaf-468d-b238-d52955dc868b

7c4450fc-aeaf-468d-b238-d52955dc868b at myworld.com: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.
