NCOR has an evaluation committee which is charged precisely with doing
that. See the NCOR wiki at http://ontologist.org. Also the NCBO
(http://ncbo.us) has a parallel effort for biomedical ontologies. (03)

The documentation of some of the alternatives DOES NOT USE CAPITAL
LETTERS IN THE STYLE OF WEBSITES DEVOTED TO THE KENNEDY ASSASSINATION. (05)

A small one is desirable (and I think unavoidable), capturing for
instance the distinction between monadic types and relations. (06)

This is one of the questions the NCOR evaluation committee will be
addressing. E.g. by comparing different ontologies in use, and
examining results. The idea is to do this scientifically, and by a
neutral body with no axe to grind. Hence I, for example, am not part of
these evaluation efforts.
