How GUIDs will be used [ Scanned for viruses ]

[Paul Kirk]

Some things happen from the top down - NOMENCLATURE - and thank god they do otherwise the chaos of (some) taxonomy would be increased by orders of magnitude ... or am I being naive?

A few quick thoughts.

But names are not unique (Agathis montana is a wasp and a tree), not
stable, there is no way to resolve them, and most of the metadata is
locked up in dead trees (journals), much of it under copyright.

The issue of centralisation and "taxonomic freedom" is a red herring
(due to Rich and I talking past each other -- my fault). My concern
(and I know I'm doing a very poor job of explaining this) is that
administrative layers and attempting to harmonise things centrally may
ultimately prove to get in the way of getting things done. My sense is
that things happen from the ground up, not the other way around. Put
another way, there is nothing technically stopping any database setting
up GUIDs today -- so what is stopping us (and yes, I'm being a little
facetious).
