Thanks Peter, for doing a great job of comparing OIL-Standard and DAML-ONT! (For those not in the know, OIL-Standard is a European funded proposal for a Semantic Web ontology language, also built on top of RDF(S), and was input to the desing of DAML-ONT. For more information, see http://www.ontoknowledge.org/oil/). One of the things that struck me in Peter's list of comparing OIL-Standard and DAML-ONT was: > OIL-Standard DAML-1.2 > > Cardinality Restrictions local (and global) global only This means that in DAML-ONT I cannot have a property "hasWheels" with a different cardinality restriction for bicycles and cars (since only one global cardinality restriction is allowed per slot). All other slot-restrictions in DAML-ONT are local (as they are in OIL). Why has cardinality been handled differently?
