Hi,

Sometimes, when we define class and individual to students, appears some
doubts.

For example:

In the owl reference (http://www.w3.org/TR/owl-ref/) class is defined as
"abstraction mechanism for grouping resources with similar characteristics"
or class define a set of individuals with same characteristics in common.

A good exemple is car (class) and ferrari enzo (individual).
But there is many cars that are ferrari enzo, so ferrari enzo could be a
class and Jonh's ferrari enzo an individual.

So ferrari enzo could be a class and an invidividual in the same ontology ?
Or ferrari enzo could be a subclass of car,
but its diferent than a tradiconal subclass like sport car.

Is there a more clear definition of class and individual ?

Thanks in advance,
Marcel
