I created a genetic ontology for Siamese cats.  So a logical query
(inference) would be:

 "Give me all male/female pairs, that when breed, produce a blue point

Genetically, I know that if the mother and father are blue points, then the
kitten can be a blue or lilac point.

Not sure how to express the above rule in DAML.  Can you recommend some
documentation and/or example for expressing inference rules?
For DAML, is it simply a matter of expressing everything as unions and 
intersection of sets?

            Blue-point kitten  = (blue-point & mother)   &    (blue-point &

I actually have a list of 21 rule based on Siamese genetics.  Just need help
expressing them in DAML.
