Anniversary of Xanadu Going Open Source

[Jeff Rush <jrush@xxxxxxxxxx>]

Greetings all.  I've just joined the list and finished reading
the archives.  Pretty sparse they are.  Is anyone interested
in further discussions about Xanada?

I'm interested in the specific technology embodied in the
green and gold sources, and perhaps someone can explain.

I have so many questions it's hard to start but before I
do, I have established a ZWiki (open-access shared whiteboard)
on my server at:

        http://www.timecastle.net/v/xanatalk

Anyone can visit and revise the contents.  In a radical move
I've opened read/write access up to anyone.  This is in
celebration of the Xanadu-going-OpenSource, one year ago.

First question:

What the *heck* is the Ent?  I have read everything I can
find and *nothing* describes its algorithms.

Roger, could you take a moment and tackle this one?  I'd
treat you to a nice dinner for a spec sufficient for
reimplementation. ;-)


Second question:

Can we get the General Theory of Enfilades down on paper
someplace?  Ted Nelson made such a big deal of it being
a breakthru and while it's a form of tree, the generalization
of the WIDativity and DSPativity to other things eludes me.
