Hi there,
Jena does not provide OWL2, correct?
Correct.
My problem is that I want to use OWL2 inference, specifically to the
qualified cardinalities inference (for instance, and is just an example,
my class IronMan is defined as all sportsman that plays at least 3
sports). With Pellet I can do OWL2 inference but I can't combine with jena
rules. In my problem, jena rules are useful because I can develop built-in
functions.
Some questions:
There are somehow to combine OWL2 inference with jena rules?
If your data is static then you may be able to put a jena rule-based
inference model on top of a Pellet-backed model.
Do you know somehow to implement qualified cardinalities in jena?
I wouldn't recommend trying that. The lack of unique name assumption
means that counting how many distinct things you have or can infer is
very tricky in a simple rule based system.
