[Pellet-users] SWRL in Pellet

Hi,

I've posted  it once, but nobody answers.

My code doesn't reason the rules, that I defined in family_rules.owl .
I don't get any error. I assume that OWL API parses the rules correctly.

Do I need to activate the rules engine inside the reasoner ? Is there
anything like that.
