Did you investigate OLAP techniques (cubes, coordinates) as a means to
model the trees?
I agree that flat table modeling via metatables
does get difficult but I did not see it outnumbering the useful
data. It is awkward. OTOH, it is one way to get the system
running on cheap desktop systems. My guess is, it doesn't
scale well and with the advent or rich datatypes and hyperlinks
as data objects, it isn't all that useful except when the
embedded renderer is the browser object.
