Re: UUIDs (Was: Software implementing Gentech Genealogical Data Model)

To relabel the discussion ...

Let me first state what should be obvious from my comments in the previous
exchanges: I know next to nothing about UUIDs or about the Gentech data
model that was being discussed.

But, back to what I've been saying, the concept of universally unique IDs
implies such an id is valid for the same entity, whatever that entity is,
everywhere that entity is found - in multiple databases on _my_ machine,
on Alice's machine, clear through to Zeke's machine. Understood that
that's based strictly on the meanings of the words universal and unique.
If there's some other definition of universally unique, with a lesser
meaning - and clearly there must be else we wouldn't be having this
discussion, flailing at one another with our slap sticks - then universal
and unique no longer have their original meanings. It just can't be both
ways.

No, the UUID algorithm is aiming at insuring that any item, at whatever
system (PC, mainframe, server, whatever) gets a TRUELY WORLDWIDE UNIQUE
identification. And that's the only way in which universal - unique should
be understood. What that item is, is completely irrelevant.
And that is quite contrary to what you're aiming at.
