Using cardinality restrictions

Hi there,

 

I’m trying to model (with Protégé 3.4.6 with Pellet Reasoner … just in case
it matters) that a class A has two subclasses B and C, where B and C are
disjoint.

The distinction I want to make is that every instance of A is either of
subclass B or of C dependent on the cardinality of a property p.

The “test” is whether the instance has values assigned to property p ( p min
1). This kind of works … the instances are interfered to be of that type.

But the other class does not work. If tried (p max 0), (p exactly 0), (p
exactly 0 RangeClass), but nothing works.

 

I’m using OWL-DL and as far as I understood 0/1 cardinalities are ok for
OWL-DL, right?

 

Thanks a lot!

Cheers,

Sören
