[DIG-users] How to ask for individuals

[Tilmann K. <dig...@tk...>]

Dear community,

I'm new to the DIG Interface an I'm facing a problem with a query I'd
like to use to find out individuals from a KB.

Suppose I've got four konzepts X, A, B, C

B is subclass of A
and
C is subclass of B

further a role "rel" connects individuals of X with individuals of A.

(I don't know the correct DIG sytax for this tells. I'm creating an
importing (in Racer) these classes with owl so that doesn't matter for
the rest of the question.)


Now I wonder how I can use DIG to ask for

... all individuals of X that are associated with at least one
individual of class exactly B

... all individuals of X that are associated with at least one
individual of class B or any subclass of B

... all individuals of X that are associated with at least one
individual of class B or any superclass of B

Thank you for your patience with a beginner,

Tilmann Kuhn
