As outcomes, we've produced an RDF representation of the FHIR specification itself, the start of a formal mapping to the RIM, and a serialization of the resources in RDF consistent with that class definitions in the FHIR specification. You can see all this here: http://hl7-fhir.github.io/rdf.html This is all very draft; there's some open issues the RDF group has been looking at which this work doesn't touch on (yet) and there's some open issues in the page as well. Anyhow, this content is ready for people to beat on, and for the RDF group to consider in depth. Grahame p.s. since I'm sure people will ask - where's the full examples? Well, the answer is, that requires the development of code to do the transform, and I'm holding off doing that until this has had a bit of review - just to save myself some work. But here's a turtle example I converted by hand from the basic example for the Flag resource: @prefix fhir: <http://hl7.org/fhir/> . @prefix flag: <http://hl7.org/fhir/Flag.> . <http://hl7.org/fhir/Flag/example> a fhir:Flag; flag:id "example"; flag:text [ fhir:Narrative.status fhir:narrative-status\#generated; fhir:Narrative.div "<div xmlns=\"http://www.w3.org/1999/xhtml\";>Large Dog warning for Peter Patient</div>" ]; flag:category [ fhir:CodeableConcept.coding [ fhir:Coding.system <http://example.org/local>; fhir:Coding.code "admin"; fhir:Coding.display "Admin"; ]; fhir:CodeableConcept.text "admin" ]; flag:status fhir:flag-status.class\#active; flag:patient [ fhir:Reference.reference "Patient/example"; fhir:Reference.display "Peter Patient"; ]; flag:author [ fhir:Reference.reference "Practitioner/example"; fhir:Reference.display "Nancy Nurse"; ]; flag:code [ fhir:CodeableConcept.coding [ fhir:Coding.system <http://example.org/local>; fhir:Coding.code "bigdog"; fhir:Coding.display "Big dog"; ]; fhir:CodeableConcept.text "Patient has a big dog at his home. Always always wear a suit of armor or take other active counter-measures" ].
Grahame, A few comments:[1] curl -I http://hl7-fhir.github.io/fhir.ttl -- returns Content-Type: application/octet-stream instead of Content-Type: text/turtle
[2] curl -I http://hl7-fhir.github.io/fhir.rdf.xml -- returns Content-Type: text/xml instead of Content-Type: application/rdf+xml
Correcting the issues above enables usability with existing Linked Open Data tools. For instance, I should be able to browse the data you've published at the aforementioned document locations, using existing Linked Open Data browsers.
Note, I am note worried about Linked Open Data publication from your location, I am simply concerned about document content-type indication accuracy.
