Okay, I've added another option: [[ Option F: '''(MUST)''' The FHIR ontology must support inference, both in use cases based on the open world assumption and in use cases based on the closed world assumption. ]] David On 02/09/2015 02:44 PM, Lloyd McKenzie wrote: Well, interoperability is de

Well, interoperability is defined by the base specification, not by any particular technology representation (schema, schematron, OWL, etc.) What really matters for interoperability is the RDF format, not the OWL. We have two use-cases for the OWL representation - instance validation and reasonin

David, I believe this question brings into play the definition of interoperability. With current technology it seems that we can get interoperability only with a closed world assumption. It all depends on the definition of interoperability (which has not been formally defined) but the expectatio

I have posted a document on the HL7 Wiki discussing FHIR Datatypes to OWL mapping - in particular the treatment of primitive types. http://wiki.hl7.org/index.php?title=File:FHIR_Datatypes_OWL_Mapping.pdf There is also a link to the document from the FHIR RDF Mapping page http://wiki.hl7.org/inde

Lloyd, that's certainly correct with the "upper bound", given the conditions that you describe. If an instance has 5 of "something" when it's declared that it should have 4, then the reasoner can clearly determine that the instance is invalid. However, using OWA, you can't do this for the "lower

Tony, Pellet 2.2.0 is available for Protege 5.0.0-beta-15 (I just checked). I'm not sure what's happened or will be happening (if anything) with Pellet 3, as I don't see a further reference to it anywhere on their Web site (and I hadn't been checking on it for a while). As I recall, the Pellet IC

I believe Lloyd is onto something critical. I view this approach as the critical bridge between traditional highly specified ontologies and schemas to more open metadata-based self-defining schemas in the world of big data. I believe further that Darwinian forces will select those highly speci
