Bill, Lewis departed for vacation at lunch time and won't be back till thursday. So as not to leave you haning for an answer till then... As taken from http://codip.grci.com/Articulation.daml the comment field for Match. "A specialization of ObjectProperty that matches its non-empty set of subjects to its non-empty set of objects." The mapping is asymmetric, from the subject ontology to the object ontology. as described on http://codip.grci.com/Tools/ArtiServicePage.html More details are discussed on the Service Page. Seems similar to DCG's but with a Match the specification of the translation between the subject(set) and object(set) is optional.

Could you please tell me what the semantics of the above are? Looks to me doing something similar to a DCG rule in Prolog. Thanks. .bill
