Hello, In my opinion, OWL 2 is a great improvement over OWL 1 since it incorporates several expressive means which are relevant for applications. However, regarding datatypes the restriction to unary relations (facets) seems unnecessary since concrete domains with n-ary relations are state of the art in DL research, and they certainly are useful in practice, since they allow to express, eg, that a car is at least as heavy as its engine. It would thus be great if datatype relations with a higher arity could be included in the final version. Best regards, Jan Hladik -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
