14:59:08 <dbooth> Chair: David Booth
14:59:11 <dbooth> Meeting: FHIR RDF
15:06:59 <dbooth> FHIR RDF Playground
15:07:09 <dbooth> https://fhircat.github.io/fhir-rdf-playground/
15:07:59 <dbooth> erich: I'm writing a java lib to make Amazon storage look like linked web storage.
15:08:15 <dbooth> ... 30-40 billion triples
15:08:42 <dbooth> ... Stress testing the use of RDF lists.
15:10:11 <dbooth> ... Complex datatypes would help, such as being discussed now.
15:11:21 <dbooth> erich: Also looking at https://www.w3.org/TR/dx-prof-conneg/
15:12:04 <dbooth> ... How would FHIR RDF be in a SOLID pod?
15:12:45 <dbooth> ericP: We used all turtle in Janeira Digital.  One thing that will be confusing: FHIR is using weak media types but claiming them as strong.
15:13:08 <dbooth> ... They're violating the rules of strong etags, in a way that makes them weak.
15:15:20 <dbooth> s/FHIR RDF Playground/Topic: FHIR RDF Playground/
15:16:36 <dbooth> erich: How FHIR compliant are EHRs like Cerner?
15:16:54 <dbooth> ericP: A lot of systems are pretty far behind, like DSTU 2 or3.
15:17:09 <dbooth> ... Paris system is using FHIR R4, but have extensions for R5.
15:18:10 <dbooth> ... Business interests want vendor lock-in, rather than standards compliance.
15:18:13 <dbooth> dbooth: I've heard that F5 doesn't have much uptake, but they expect R6 to have more.
15:19:47 <dbooth> gaurav: Playground has a bunch of IRI code, and some tests.  I wrote a PR that fixes that.
15:20:26 <dbooth> ACTION: EricP to review gaurav's playground PR
15:20:54 <dbooth> Present: EricP, Erich Bremer, Jim Balhoff, Gaurav Vaidya
15:25:52 <dbooth> Topic: URIs for FHIR Paths -- issue 61
15:25:53 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/61
15:30:46 <dbooth> Agreed to close due to lack of interest/expertise.
15:30:48 <dbooth> Topic: Update HAPI server to RDF R5 features #100
15:30:56 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/100
15:31:14 <dbooth> ericP: Waiting for ShEx validation of examples
15:32:16 <dbooth> Topic: Need to re-enable shex validation in FHIR build #81
15:32:35 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/81
15:32:56 <dbooth> jim: round-trip validation has been disabled for a long time, because it is too slow.
15:33:11 <dbooth> ericP: ShEx validation is also disabled.
15:33:32 <dbooth> ... Grahame made a change that broke it, and it took a lot of time to figure out why.
15:33:41 <dbooth> ... But it also took a long time to run.
15:34:02 <dbooth> ... Iovka is working on an efficient validator for current FHIR RDF ShEx (using EXTENDS).
15:34:23 <dbooth> ... Claude and I will work w her in Lille on that (in a few days).
15:35:19 <dbooth> ... Then it could be re-enabled in the build process.
15:37:38 <dbooth> dbooth: EricP is planning to get this working again soon, and hoping to get it back into the FHIR build process.
15:46:28 <dbooth> Topic: Add a top level node for each FHIR code ontology? #57
15:46:34 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/57
15:47:27 <dbooth> Present+ Rob_Hausam
15:49:05 <dbooth> rrsagent, pointer?
15:49:05 <RRSAgent> See https://www.w3.org/2025/05/01-hcls-irc#T15-49-05
15:50:01 <dbooth> dbooth: I think this would become more important to folks who are using the FHIR valuesets in reasoning
16:00:00 <dbooth> dbooth: Closing due to lack of interest/expertise.
16:00:06 <dbooth> Topic: FHIR RDF ontology URLs do not resolve #48
16:00:12 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/48
16:00:36 <dbooth> jim: The classes in our ont have URLs that do resolve.
16:01:00 <dbooth> ... e.g. http://hl7.org/fhir/ClinicalUseDefinitionWarningComponent
16:04:32 <dbooth> ericP: The way forward would be to come up w a compelling use case, then go to Grahame.
16:06:52 <TallTed> TallTed has joined #hcls
16:14:55 <dbooth> dbooth: That's assuming we don't change the URIs.  Another possibility would be to change those URIs, to put them under subdirectories that we can more easily control.
16:15:08 <dbooth> ADJOURNED
