This is an important distinction to make, because I also maintain this
distinction.:-).  Well, in the design of GNOWSYS classification is
done separately by adding ObjectTypes and Objects, and associations as
other kind of relations..  This is to essentially take care of the
most widely used knowledge organizer `instanceOf'.  Logically
instanceOf is a kind of transitive relation, but it is good to have
this widely used relation separate for pratical reasons.
