[Pellet-users] Get domains for a property

[Evren Sirin]

You can get the domain of a property by asking the super classes of 
concept expression (p some owl:Thing). What you describe below is a 
little different and you wouldn't get any superclasses for this 
expression. You can query for the subclasses of the expression and in 
your example you would get both C1 and C2. But note that querying for 
subclasses finds concepts that necessarily have the property value, i.e. 
if all you had in the ontology is a global domain axiom then you 
wouldn't get any answers for this second query.

Cheers,
Evren
