15:59:54 <dbooth> rrsagent, make logs public
16:00:06 <dbooth> Meeting: FHIR RDF
16:00:33 <dbooth> Chair: David Booth
16:04:21 <dbooth> Topic: FHIR Build
16:05:49 <dbooth> jim: Opened a couple of PRs.  One on FHIR Core, and the other on Kindling.  https://github.com/HL7/kindling/pull/111
16:06:42 <dbooth> https://github.com/hapifhir/org.hl7.fhir.core/pull/1110
16:07:12 <dbooth> jim: Also theh profiles (structure defs)
16:08:00 <dbooth> jim: Looking at this example: http://hl7.org/fhir/patient.profile.ttl.html
16:09:32 <dbooth> dbooth: propose address other things first.  the Turtle structure defs are less important.
16:12:29 <dbooth> eric: We're looking at the meta level.  Claude helped him work out a list of lower priority things.
16:13:05 <dbooth> eric: Low priority to even look for problems at the meta level.
16:13:42 <dbooth> dbooth: Agreed.
16:14:48 <dbooth> dbooth: I saw what looked like extra type arcs.
16:15:50 <dbooth> jim: fhir:deceased[x] has type arcs.
16:16:15 <dbooth> dbooth: Okay, that looks right.
16:16:24 <dbooth> eric: Multi-line comments in examples?
16:16:41 <dbooth> jim: That's still a problem.  Will try to fix it.
16:19:36 <dbooth> jim: loinc concept IRIs are hard coded.
16:20:39 <dbooth> dbooth: Loinc prefix should be https://loinc.org/rdf/
16:20:50 <dbooth> ... per Gaurav's google doc.
16:23:13 <dbooth> dbooth: Suggest adding others defined in the Gaurav's document: https://docs.google.com/document/d/1sW3Tgj2J_wBzlUWih07e0Vf_M9Ue8YyPqjK0arhajS8/edit#
16:24:37 <dbooth> jim: There's parsing work to be done also.
16:25:24 <dbooth> dbooth: Discussing parsing FHIR RDF and going back to FHIR JSON or XML.
16:27:11 <dbooth> jim: Can we drop that code?  Is it used for anything?
16:27:24 <dbooth> eric: Maybe was used for round-trip testing.
16:27:58 <dbooth> ACTION: Jim check w Grahame about dropping the RDF parsing code (in favor of HAPI).
16:29:56 <dbooth> Topic: Ont generation
16:30:13 <dbooth> Present: Daniel Stone, Rob Hausam, Jim Balhoff, EricP, David Booth
16:30:37 <dbooth> daniel: Made two commits for updates.
16:30:58 <dbooth> https://github.com/Fhircat/kindling/tree/R5_ontology_update
16:31:04 <dbooth> https://docs.google.com/spreadsheets/d/1Ncjs-AAFWZEtP0KCEjTcUJa_HMVeg4Xoh3QPFEW6C0s/edit#gid=0
16:33:34 <dbooth> eric: Tried to see if there were commonalities between the various FHIR properties.  In principle that would be a nice-ish way to populate the rdfs:labels.
16:34:18 <dbooth> dbooth: How should daniel gen the rdfs:labels ?
16:35:10 <dbooth> eric: 1. Grab the first of each.  2. omit rdfs:label 3. Hand-craft the property names.
16:36:22 <dbooth> dbooth: Option 4.  How about concatenate them all?
16:36:42 <dbooth> eric: Option 5: Do option 4 but hand-craft some conspicuous ones.
16:37:46 <dbooth> daniel: Generated a subset for key elements we might care about.
16:38:42 <dbooth> ... Then ran rdfdiff to compare latest changes.
16:41:48 <dbooth> eric: Maybe we should not invent generic labels, since they are not currently in FHIR.
16:43:00 <dbooth> dbooth: Propose concatenate the labels for each property, separated by vertical bars,  into an rdfs:label
16:44:59 <dbooth> eric: Proposed generic labels might motivate the FHIR group to create generic labels.
16:46:04 <dbooth> ... They already have a need for such a doc.
16:46:26 <dbooth> rob: Partly agree.  Slowly trying to converge.
16:49:01 <TallTed> TallTed has joined #hcls
16:53:51 <dbooth> AGREED: Including truncated concatenated labels is better than omitting them.
16:56:05 <dbooth> AGREED: Daniel should use a list of generic labels if he has time, and fall back to trucated concatenated labels for others.
16:56:59 <dbooth> Topic: Punning for shortened propoerties?
16:57:17 <dbooth> AGREED: Use punning.
16:59:55 <dbooth> daniel: What other OWL assertions do we need?
17:00:10 <dbooth> dbooth: I think we need these:
17:00:12 <dbooth> [[
17:00:12 <dbooth> 1. Add global declarations:
17:00:12 <dbooth> fhir:_Resource rdfs:subClassOf [ owl:onProperty fhir:modifierExtension; owl:minCardinality 1 ].
17:00:12 <dbooth> [] a owl:AllDisjointClasses ;
17:00:13 <dbooth>     owl:members  ( fhir:Resource  fhir:_Resource ) .
17:00:13 <dbooth> 2. And for each FHIR resource such as fhir:Obs, add this declaration:
17:00:15 <dbooth> :_Obs rdfs:subClassOf fhir:_Resource.
17:00:17 <dbooth> ]]
17:03:15 <dbooth> jim: Seems ok to me.
17:06:47 <dbooth> eric: Not sure it should be fhir:Resource.  Maybe fhir:DomainResource.
17:07:04 <dbooth> eric: need to investigate more.
17:07:54 <dbooth> daniel: example:
17:07:55 <dbooth> [[
17:07:56 <dbooth> This is the only way that I could get blank node to appear in code atm:
17:07:56 <dbooth> [ a            owl:AllDisjointClasses ;
17:07:56 <dbooth>   owl:members  ( fhir:Resource fhir:_Resource )
17:07:56 <dbooth> ] .
17:07:57 <dbooth> ]]
17:08:15 <dbooth> eric: That's fine that way.
17:09:14 <dbooth> ACTION: DBooth to investigate whether it should be fhir:Resoruce or fhir:DomainResource
17:09:30 <dbooth> http://hl7.org/fhir/extensibility.html
17:09:36 <dbooth> • There are a few resources (ones that do not specialize DomainResource) where extensions are not allowed on the root element, but extensions can appear elsewhere through the resource
17:09:51 <dbooth> eric: Can look at the content model of them, and also at the datatypes.
17:11:24 <dbooth> dbooth: So that quote Rob found indicates that the declaration should be for fhir:DomainResource and fhir:_DomainResource
17:11:50 <dbooth> eric: And only declare them on individual resources that are under fhir:DomainResource .
17:12:34 <dbooth> ... directly or indirectly.
