Michel, On 14th June 2000, in: http://lists.w3.org/Archives/Public/www-rdf-comments/2000AprJun/0045.html you raised an issue against RDF Schema suggesting that the restriction that cycles in subClassOf relationship are not allowed, should be removed. On 21st September 2001 http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Sep/0326.html the RDFCore WG decided: To resolve issue rdfs-no-cycles-in-subClassOf by deleting the restriction prohibiting cycles of subClassOf properties. The meaning of a cycle of subClassOf properties being an assertion that the classes involved have the same members. A more formal specification of the meaning will be given in the model theory. Please can you reply indicating whether this change is a satisfactory resolution of your objection. You might also note that the WG also decided to allow cycles in subPropertyOf relations as well, at the subsequenct teleconference on 28th September. Brian McBride RDFCore co-chair
