15:59:11 RRSAgent has joined #hcls 15:59:15 logging to https://www.w3.org/2023/12/14-hcls-irc 15:59:15 rrsagent, make logs public 15:59:42 Meeting: FHIR RDF 15:59:45 Chair: David Booth 16:03:42 Topic: Concept IRIs 16:04:20 gaurav: Emailed ITS committee about minor changes to make to UTG records for LOINC. 16:04:32 ... Want to link directly to fhir.org 16:05:05 ... But it needs to be approved by ITS. Meeting Wed Jan 3, 3p Eastern. I'll join. 16:05:32 ... I'll be working next week, then out the following week. But want to get the MeSH proposal ready for them to vote on that also. 16:06:45 ... Also want to pursue radlex, but need to check with them first. 16:07:50 dbooth; Contact for radlex? 16:08:19 rob: Look on the HTA page on confluence. They would have talked with radlex. 16:08:22 TallTed has joined #hcls 16:08:39 https://confluence.hl7.org/display/TA/RadLex 16:09:00 gaurav: URLs in their ontology are resolvable. 16:10:47 Topic: Issue 120 canonical URIs. 16:13:37 https://github.com/w3c/hcls-fhir-rdf/issues/120 16:14:24 ericp: Difference bewteen options 1 and 4 is that 1 is intentional and 4 is specific. 16:14:46 ... 4 uses proposal B. 16:15:50 Present: EricP, Erich Bremer, Tim Prudohomme, Rob Hausam, Gaurav Vaidya, Jim Balhoff, David Booth 16:22:19 tim: This example uses fhir:instantiatesCanonical: 16:22:19 https://build.fhir.org/procedure-example-f201-tpf.ttl.html 16:26:52 rob: Must have dealt with polymorphisma on observationValue 16:27:54 https://build.fhir.org/observation#a14. 16:28:31 eric: 3 ways we could do this. 1 if it's a complex type. 2. It's a primitive type with an XSD datatype, like xsd:datetime. 16:29:07 ... 3. It's a primitive, but the xsd is a string and we need a type arc on the blank node. 16:29:47 ... valueDateTime is already clear becuase the xsd type is in the value. 16:30:25 tim: Currently the fhir:Reference values of fhir:subject in the examples do not have fhir:link , so that would need to be added, right? 16:31:29 https://build.fhir.org/procedure-example-f201-tpf.ttl.html 16:31:51 ericp: Yes, all the references shold have links. 16:36:38 This example: shows a fhir:value [ a fhir:Quantity ; ----> https://build.fhir.org/observation-example-f001-glucose.ttl.html 16:36:49 ... ( omplex type) 16:38:24 ericp: Another complex value example: Observation.valueSampleData: https://build.fhir.org/observation-example-sample-data.ttl.html 16:39:36 ... This one is a primitive with no xsd type indicated: Observation.valueString: https://build.fhir.org/observation-example-eye-color.ttl.html 16:40:10 ... (defaults to xsd:string in turtle) 16:40:56 dbooth: Need to collect these examples, itemize them, then say what we think should happen. 16:41:44 AGREED: Everything that points to something else in FHIR should have a link 16:42:17 ericp: I think that's only Reference and canonical 16:43:35 tim: Do we want to do the version thing in any of the links? 16:44:00 eric: Proposal 4b involves cutting off the version at the pipe, and putting it into a query string. 16:47:37 tim: Should we change those xsd:anyURI types to xsd:string? 16:47:58 ericp: I don't think we should try to be holier than the XML folks. 16:50:50 eric: New issue is how we discriminate polymorphic primitive types 16:53:09 rob: There's a slight different between a choice and value[x] polymorphism. 16:55:01 ericp: I'm guessing that, other than value[x] cases, the only places where it is polymorphic are using Reference or Canonical. 16:59:26 ADJOURNED 17:00:26 rrsagent, draft minutes 17:00:28 I have made the request to generate https://www.w3.org/2023/12/14-hcls-minutes.html dbooth 17:35:28 TallTed has joined #hcls
