Really interested in the take of others here - there are a couple of ways of looking at this - but I have never been able to find a cogent argument why we shouldnt assume that a rdfs:Class is actually a type of skos:Concept - classes are nothing more that concepts that define sets of instances. It seems to be explicitly supported in OWL 2 as "punning" [https://www.w3.org/2007/OWL/wiki/Punning] It seems a perfectly natural Use Case to me to model skos:Concepts as types in systems, then generate rdfs: and owl Class models only if and when we need to model additional behaviours. skos:Concept is relevant for "soft-typing" and rdfs:Class for hard-typing - and the equivalence is actucally a useful thing. Is OWL-Full really a problem? I think not for several reasons: 1) I dont see evidence that OWL-DL (or any other flavour) inferencing is happening at run-time across distributed systems - all "semantic web" implementations I have see cache any models they want to use. 2) There is currently no way of telling a client, not specification, constraining referenced models to be any particular profile of OWL - so no assumptions can be made anyway 3) With negotiation-by-profile the same concept can be served with a graph that conforms to SKOS, RDFS, OWL-DL, OWL-Full, SHACL and any other specific profile needed by a client. IMHO there is a need to provide a specific example of the problem and why its a problem, and how to handle the use cases of soft-typing. My feel here, although I can prove it, is that negotiation by profile and OWL 2 punning are two sides of the same coin - implementation and theory, and essentially we can get out of the bind by the URI dereferencing architecture - OWL-DL reasoners can ask for the metaclass representation they want. Default behaviour for OWL - i.e. if a client asks for OWL perhaps an OWL-DL representation SHOULD be returned. I dont know if the profile guidance or content negotiation scope will allow us to go into this platform specific detail - or where and who in W3 cares about the general architecture of distributed OWL models? -- GitHub Notification of comment by rob-metalinkage Please view or discuss this issue at https://github.com/w3c/dxwg/issues/314#issuecomment-413795569 using your GitHub accountReceived on Friday, 17 August 2018 08:28:06 UTC
