OK, I see if that is the case then that's OK with me as well I tested it a bit and started from DanC's rules and came to owl:AllDistinct rdfs:subClassOf rdf:List. {?L rdf:first ?x. ?L rdf:rest ?M. ?M owl:item ?y. ?L a owl:AllDistinct} => {?x owl:differentFrom ?y}. {?L rdf:rest ?M. ?L a owl:AllDistinct} => {?M a owl:AllDistinct}. I just don't see how rdf:parsetype="Collection" could work in this case, but anyhow, e.g. <owl:AllDistinct rdf:nodeID='A0'> <rdf:first rdf:resource='premises001#a'/> <rdf:rest rdf:nodeID='A1'/> </owl:AllDistinct> <owl:AllDistinct rdf:nodeID='A1'> <rdf:first rdf:resource='premises001#b'/> <rdf:rest rdf:nodeID='A2'/> </owl:AllDistinct> <owl:AllDistinct rdf:nodeID='A2'> <rdf:first rdf:resource='premises001#c'/> <rdf:rest rdf:resource ='http://www.w3.org/1999/02/22-rdf-syntax-ns#nil'/> </owl:AllDistinct> should entail <rdf:Description rdf:about="premises001#a"> <owl:differentFrom rdf:resource="premises001#c"/> </rdf:Description> -- , Jos De Roo, AGFA http://www.agfa.com/w3c/jdroo/ Frank van Harmelen <Frank.van.Harmelen To: www-webont-wg@w3.org @cs.vu.nl> cc: Sent by: Subject: Re: oneOfDistinct, a proposal for 5.18 www-webont-wg-reque st@w3.org 2002-12-20 11:11 PM Please respond to Frank van Harmelen Jim Hendler wrote: > If the WG indicates that they agree with Peter and/or prefer this decision, > I will be willing to revisit our decision.

My first preference is Peter's proposal and I would rather not have unique-names construction at all, rather than going to LC without a semantics document. Frank. ----
