This follows from the fact that what is best suited for one purpose may
not be best suited for another.  If one application uses a narrow number
of concepts, it need not have upper ontology components irrelevant to
the application.    (03)

Certain ontology languages allow types of components that others disallow:
classes of classes, subclasses of datatypes (even numbers, vowels),
variable-arity relations, ternary (or higher-arity) relations, functions,
functional predicates, relations among relations ...  Such types of
things might exist in one ontology, but not in another.    (04)

A key division in one ontology might be the perdurant/endurant distinction,
while a 4D ontology might disallow it.  Some ontologies would include
concepts such as events and situations, while others would exclude them,
using relations to model occurrences of these things.  An ontology of
financial accounts might not need the concept of PhysicalObject, while
one on galactic astronomy would not need the concept of IntensionalAgent,
although these might be crucial for other ontologies.    (05)
