Hi, I'm interested in what CANNOT be represented (declared) in OWL/DAML. Your comments or pointers to papers are much appreciated. What I'm hoping to do is to be able to represent constraints (or axioms or rules) in a DAML ontology so that an inferencing engine can check the ontology for consistency. For instance, if I have <age rdf:about="#Tom"> <age_type rdf:about="#child"/> </age> <age rdf:about="#John> <age_type rdf:about="#man"/> </age> <less rdf:about="#child"> <age_type rdf:about="#man"/> </less> in the DAML ontology, I would like to define an axiom <younger> in terms of <age> and <less> in such a way that the additional statement <younger rdf:about="#John"> <age_type rdf:about="#Tom"/> </younger> would be flagged as inconsistent. Much thanks
