It seems okay for the > server to throw an error if an unsupported entailment regime is requested. +1 We currently have sd:supportedEntailment in the SD vocabulary - so sd:defaultEntailment would probably make sense. -> User retrieves the endpoint's SD so can check if he's happy with the default one, or wants to apply another regime to the query. Yet, there is still a need to figure out how this can be specified. [1] seems indeed to be out of scope, but there was complex use-cases in there (RULESET, ontologies, etc.). What about a limited set of available RULESET patterns ? (RDFS, etc.) Alex.
