One comment: you have a tick for reification under DAML+OIL. Although it is true that reified statements are allowed in DAML+OIL expressions, we do not give them any particular semantics beyond what is already defined in RDF(S) (if anything). So I think it would not be fair to claim this as a "feature" of DAML+OIL? Also, I think there is a broad feeling in the committee that the reification of RDF(S) is either broken, or not what you want, or both, and if we wanted reification in DAML+OIL, it would probably look quite different from what RDF(S) does now? I also quickly looked at your talk. Good! Frank. ----
