[O] "atomic knowledge" modeling tool

[luke call]

There's a program that org-mode users (as I have been) specifically 
might be interested in, a personal "knowledge manager"/list 
manager/organizer/etc called OneModel (Free/AGPL).  Instead of storing 
data as text, it puts *everything* in a single object model backed by 
postgresql, but text import/export are available.  Everything one needs 
to know at any given time is always on the screen, and it is *highly* 
efficient to navigate (so far keyboard-only).  Current strengths, 
limitations, and future plans are at:

Pls forgive & spare the flames, I'll probably go quiet unless to answer 
good-faith questions.  Details & discussion at http://onemodel.org 
site/lists if desired.
