Rather than a simple heirarchical thesauraus, which would be
"taxonomically" organized (i.e., a species would be a member of one genus
which would be a member of one family, etc.), let me speak in favor of the
"parent-child" model, which was implemented in the Lotus Agenda program
(which, had it had a decent looking interface probably would not have
disappeared).

In this approach, a single "child" category can have several parents --
i.e., the category "benzene" can simultaneously be a member of "parent"
classes "organic compounds", "solvents", "fuels".  This would permit (with
appropriate inheritance rules) the type of flexible searching that I think
that we all desire -- i.e., if we want to search for "solvents" and have
previously defined "benzene" to be a member of that class, then the search
would include all references keyed to benzene.

I think that the biggest complication would probably be programming this to
deal with moving and rearranging classes and inheritance properties.
