[Opensim-dev] standardizing on uuid string formats

[Kyle Hamilton]

First: +1 for hyphens.  They're the standard format as described in
RFC4122, ITU X.667, and ISO/IEC 11578:1996.

I think there's a design (DHT) that might allow the UUIDs to not have
to carry information about the originating grid.

However, there's a question I have: What is the mechanism that OpenSim
uses right now to allocate a new UUID?  If (and only if) it adheres to
RFC 4122, it can actually guarantee node- and time-based uniqueness
(at least for long enough that a different identification standard to
come forth).

See http://www.famkruithof.net/guid-uuid-make.html for a more
human-readable description of how to create UUIDs that are unique.
