Michael, There are reasons for and against representing topics as classes and relating them via subClassOf. Natasha Noy at Stanford has written a useful overview of the issues which you may want to look at. I'm offline and don't have the reference to hand but I think it's entitled "Using Classes as Property Values" and can be found on the W3C website (www.w3c.org). In the SEKT project (www.sekt-project.com) we are also looking at the ontological representation of a document classification scheme and other associated metadata in the context of a Digital Library case study. If you are interested, email me off-list for a further discussion. Regards, John Davies.

Since searching for a simple and useful example I want to build up the ACM classification index in OWL. My approach is to express each classification entry as an owl:class concept, relating them via rdfs:subClassOf. That is pretty simple. However the ACM classification index encodes references between certain entries too (e.g. B.2.3 ["Reliability, Testing, and Fault-Tolerance Reliability, Testing, and Fault-Tolerance"] is related to B.8 ["Performance and Reliability"]) . So my question here is how to model those references in OWL. I believe using the equivalentClass construct is not appropriate, because those classes have not same instances. Could anybody give me an enlightening idea please? thanks in advance Michael Engelhardt .me
