I'm very interested in the work that's going on around federation, and
I'm also drawn to the value of robust history tracking for tiddlers,
and agree that that is one of the key roles for servers in the
TiddlyVerse.

I've found myself less keen on making UUIDs be a part of the core
definition of a tiddler. I can see that there are some scenarios that
need UUIDs to work, and so I'm interested in ensuring that the core
definition of a tiddler allows for the use of UUIDs (the simplest way
being to choose to use UUIDs in the title field, and use a different
field for the human readable title). I don't see a role for UUIDs in
the TiddlyWiki core, rather I see their usage being driven by server
side (or federation) concerns.

Adding UUIDs to the core tiddler model would make tiddlers more
specific to a particular class of servers and/or federation systems.
Some of these systems might well want slightly different semantics for
UUIDs. If the tiddler concept is to be universal then I think it needs
to be surgically minimal: it is primarily about cutting up information
into little chunks, and the details of particular persistence or
federation approaches using UUIDs shouldn't intrude on the core model.
We want the idea of a tiddler to be as simple as possible so that as
many people as possible can agree on it.

Best wishes

Jeremy
