[Opensim-dev] Global identifiers

[Karen Palen]

The type 1 UUID that I  proposed earlier would act more as a timestamp and
authenticator than as URI.

The type 4 (random) UUID is better suited for many purposes since it is
inherently anonymous, but the idea here is to act as a verification of
content creator (IM or whatever) as they existed at a particular point in
time. This can also be useful for unambiguous identification of freinds and
IM originations - certainly not foolproof, but useful all the same.

I don't think the inherent privacy issues would impact any foreseeable use
in the context of a public identifier such as this.

The fact that the user/organization later changes domains after creating the
identifier, computer/MAC addresses is really irrelevant since (as I
understand it) this is intended to identify somehting created at a
particular time and place.

Yes the type 1 and type 4 UUIDs are compatible, there is a built in
identifier field which tells which type is used. Figuring out which is
legitimate (or correct) in a specific situation is a higher level problem.
