14:57:59 RRSAgent has joined #hcls 14:58:03 logging to https://www.w3.org/2023/06/01-hcls-irc 14:58:34 rrsagent, make logs public 14:58:35 Meeting: FHIR RDF 14:58:35 Chair: David Booth 15:04:54 Topic: Introductions 15:05:20 Present: David Booth, Max Burton, Allen Flynn, EricP, Gaurav Vaidya 15:08:15 max: From Medtronic, building interactions w FHIR and EHRs. Investigating using RDF for representing our data. Primarliy work on arch. Saw the video w Harold on uing JSON-LD into RDF. 15:08:28 dbooth: Still plannig to use JSON-LD? 15:08:49 max: Yes, using the framing apect of JSON-LD -- framing service for JSON data. 15:09:04 ... RDF comes into the backend side for transferring. 15:09:22 eric: Is your framing target isomorphic to the graph structure. 15:09:34 max: IDK yet. 15:09:49 eric: JSON-LD does not invent nodes. 15:10:51 Topic: Concept IRIs 15:11:03 gaurav: No progress since last week. 15:11:26 ... Still wrinting a prog to pull all the code sys and naming sys from the repo. 15:11:45 Topic: HAPI 15:12:34 eric: Resurrected the HAPI server. Still focused on jena shex. Also working w Deepak on validating the examples against the shex. 15:13:36 ... There's a bug in Jim's generated RDF. For codings, the datatype is a fhir:code, and the XML of that is an xsd:token, but they were represented as xsd:strings, so they were rejected in the validation. 15:14:07 ... But since it was only codes, deepak hand edited the schema for code to allow either string or xsd:token. 15:20:29 topic: OWL to FHIR transformers 15:21:26 gaurav: THere were some old ones https://github.com/aehrc/fhir-owl , and there is now some discussion in zulip on a new effort. 15:21:45 ... Foundational model of anatomy 15:21:55 https://chat.fhir.org/#narrow/stream/179202-terminology/topic/FMA.20.28Foundational.20Model.20of.20Anatomy.29 15:22:31 ... And TSMG is discussing this, also about CPT. 15:22:48 #narrow/stream/179202-terminology/topic/AMA.2C.20HL7.20Partner.20on.20FHIR.20CPT.20Integration.20to.20Drive.20Interop 15:23:04 ... It sounds like AMA agreed to let CPT to be shared in FHIR. 15:23:15 eric: Only as a code system, or also logical models? 15:23:20 gaurav: Code sys. 15:23:41 ... FMA is not going to terminology.hl7.org. Someone just wanted to use it. 15:23:52 ... I think as a code system. 15:24:05 ... I think that's what the OWL-to-FHIR tools do. 15:24:22 eric: As giant valuesets? 15:24:53 gaurav: The new tool was demoed, and it turned it into a massive code set -- one term every every term in the ont. 15:25:21 ... They were working on HPO ont. 15:26:08 eric: The OBO Foundry has formal rules about modeling things. FMA is Foundational Model of Anatomy -- about what is a part of what. 15:26:36 ... CPT is from AMA. 15:27:08 ... There was a press release saying that AMA is partnering w HL7. 15:28:19 gaurav: They're also looking at how they can put the terminology into terminology.hl7.org, but might have a licensing issue. 15:28:37 eric: what use cases? 15:29:43 gaurav: If the terms exist in HTO then presumably they could validate 15:31:07 Topic: FHIR ShEx 15:31:42 eric: it has about 1500-2k shapes, and you need a dedicated shape for every list, because it needs to be able to point to itself, so it needs a label. 15:32:22 ... Is there willpower and energy to add templates to ShEx to allow you, instead of creating ListOfX, to say you have a llist template w parameter X. 15:32:58 ... Purpose would be to get that done before finishing shex "extends", to get it into the IEEE standard. 15:33:59 dbooth: Like a macro expansion? 15:34:40 eric: That's one of the big questions. Could be a syntax trick. Or it could be built into the semantics of the language, and gives more power and allows round tripping. 15:35:11 ... To do it right would require someone think hard about it. 15:35:46 dbooth: Sounds worthwhile. 15:37:26 ADJOURNED 15:37:31 rrsagent, draft minutes 15:37:32 I have made the request to generate https://www.w3.org/2023/06/01-hcls-minutes.html dbooth
