15:58:13 RRSAgent has joined #hcls 15:58:13 logging to https://www.w3.org/2021/12/02-hcls-irc 15:58:18 rrsagent, make logs public 15:58:22 Meeting: FHIR RDF 15:58:24 Chair: David Booth 16:02:38 Topic: Context generation 16:03:02 james: working w EricP 16:04:08 Topic: Issue 76: Ordered lists 16:04:17 https://github.com/w3c/hcls-fhir-rdf/issues/76 16:06:10 jim: Figured out my error, got @list working to round-trip RDF lists using framing. 16:07:10 david: Does the frame need to be different than the @context, or can it be the same? 16:07:40 jim: Mostly the same, but also need to say what node you want at the root. 16:08:44 david: Similar to fhir:nodeRole fhir:treeRoot ? 16:10:00 david: Could it be a part of the standard @context/frame or is it specific to the instance data? 16:11:24 jim: I think it is based on the structure, not the instance data. 16:12:34 gaurav: I think it may need to be separate from the @context. 16:13:22 david: I had the opposite impression, but IDK. 16:14:42 ACTION: Jim to see if framing can be in the @context 16:15:15 ACTION: Jim to try out some round tripping made. 16:16:19 Topic: FHIR JSON-LD playground 16:16:31 eric: Made lots of progress: https://ericprud.github.io/fhircat-playground/playground/ 16:17:48 ... Need to generate lots of @contexts. Made an on-the-fly @context generator, fired by loading the FHIR structure def. Makes the @context production faster. 16:18:27 ... Only replicated what we had before, but in process of adding more functionality to FHIR JSON-LD playground. 16:19:18 ... Need a github repo for it, cuz it needs to own the github.io. 16:20:18 ... Making a library for it. 16:22:17 ACTION: James to check in his FHIR JSON-LD code and compare with eric's code 16:23:01 Topic: issue 94, lack of concept URIs for CodableConcepts 16:24:24 gaurav: code system is identified by both system and code. Challenge is to add a prefix to the code, to produce a proper URI. But the prefix is not always the same as the system URI. Looking to see if there is a repo of these codes. 16:26:11 david: system is a namespace for a set of codes 16:27:17 eric: a valueset is a subset 16:28:20 s/subset/subset of codes from one or more system 16:32:00 eric: NamingSystem is like a namespace document in RDF land. 16:33:27 gaurav: NDC page gives details info about how to make the codes. 16:34:45 gaurav: Both CodeSystem and NamingSystem documents are machine readable. 16:34:56 ... They're available from HL7 site. 16:35:44 TallTed has joined #hcls 16:39:59 david: What URI goes into System property in instance data? 16:42:27 ... It looks like the NamingSystem is additional documentation about the CodeSystem. 16:42:59 ... And it seems to be non-authoritative third-party annotations on the CodeSystem. 16:46:12 gaurav: CodSystem has only one defining URI, but NamingSystems can have multple identifiers. 16:49:49 gaurav: The HL7 terminology website has a registry for FHIR CodeSystems. If we can get the prefixes put in there, that would be a good place for them. 16:51:54 gaurav: To get it in there, maybe needs to be added to a NamingSystem 16:53:40 ACTION: Gaurav to see if prefix could be added to CodeSystem definitions 16:55:13 eric: We postulated that HL7 would publish a URL template for CodeSystem URIs, and the owner would then claim it. 17:00:08 gaurav: If we can convince HL7 to add a prefix field to CodeSystem definition, then we're off to the races. 17:00:20 ADJOURNED 17:34:38 Present: Jim Balhoff, EricP, Gopi, David Booth, James Champion, Gaurav Vaidya 17:36:20 rrsagent, draft minutes 17:36:20 I have made the request to generate https://www.w3.org/2021/12/02-hcls-minutes.html dbooth
