15:56:34 <dbooth> Meeting: FHIR RDF
16:00:39 <TallTed> TallTed has joined #hcls
16:03:12 <dbooth> Topic: R6
16:03:51 <dbooth> detlef: We found some missing parts in the fhircat fhir RDF parser
16:05:03 <dbooth> ericp: Tim was working on getting me a dump of the shex and examples, then i was going to run validation and fix what is needed.  Make sure they round-trip.
16:05:14 <dbooth> ... into HAPI.  Then validate HAPI output.
16:05:48 <dbooth> ... Tim was going to gen that from an R5 release.
16:07:49 <dbooth> Topic: Extending our ont for more semantic interop
16:08:06 <dbooth> ken: COuld be a huge effort.  Should validate business cases.
16:08:42 <dbooth> ... Want cross-product domain with AI applications.
16:09:22 <dbooth> ... I have standard product messages coming across.  Some places I've seen in public health have to do w FHIR, CCDA, and US x12 and v2.  All are involved in that process.  Also E-prescription.
16:09:50 <dbooth> ... The other is NLP.  When you take unstructured data and you need to structure it to harmonize, having an ont is beneficial.
16:11:00 <dbooth> ... Most of this is on a volunteer basis, and if does not align with people's day jobs, it's hard to get cycles.
16:12:07 <dbooth> ericp: Sounds good, but predicated on starting w use cases and queries.
16:12:55 <dbooth> ken: I have a use case abt info transform.  But I'm not an SME for query, with inferencing.
16:13:29 <dbooth> ericp: If you can point to "here's what I imagine", we can make sparql query.
16:13:57 <dbooth> ACTION: Ken to write up issue w suggested use case
16:19:11 <dbooth> ken: There can be a mismatch btwn an ont and FHIR data model, and how we navigate those things.
16:20:41 <dbooth> dbooth: this RDF subgroup of ITS is responsible for the RDF format of the FHIR standard.
16:21:05 <dbooth> ... The ont is an extra benefit.
16:23:55 <dbooth> ... FHIR license is CC0: https://build.fhir.org/license.html
16:24:21 <dbooth> ... And W3C has a clear patent policy that requires free use
16:24:59 <dbooth> ken: Example of ont problem, driven from social services -- housing insecurity in USA.
16:25:21 <dbooth> ... It's provided to a household (set of people) who have a set of constraints put on them by fed and local govs.
16:25:33 <dbooth> ... We were not allowed to use the concept of a person.
16:26:51 <dbooth> ... Also, person relations are important.  That's getting some traction, because in FHIR data model only allowed patients, and the only rel they could have was to a related person, and only 1:1.  Caused modeling problems.
16:30:17 <dbooth> dbooth: I believe the FHIR RDF group can add the concept of a person to the FHIR ont if we want.
16:33:43 <dbooth> ken: Eric Jahn and I have worked on that.  This community group is a joint effort between W3C and HL7.
16:34:58 <dbooth> ... If we decompose, there's the RDF level, then there's the FHIR ont.  It's independent of the RDF.  WE have freedom in the ont.
16:36:07 <dbooth> ericp: The ont w capture what we can get from the structure def.  But if you want to add extra connective elements and inference we can.
16:37:43 <dbooth> ericj: HUD is using FHIR RDF, and Temple Univ also, for their DreamKG (NSF-funded) addressing homelessness.
16:40:27 <dbooth> Topic: Attribution for our work
16:40:59 <dbooth> dbooth: Sebastian did an ack list.
16:41:40 <dbooth> detlef: Do we have some place for ack contributions visibly?
16:44:17 <dbooth> ericp: Suggest we attach messages mentioning product.  Eg., we have FHIR R6, and thank the following contributors.
16:44:38 <dbooth> detlef: Need to discuss with our marketing guy.  But everytying would be helpful.
16:45:20 <dbooth> ericp: The front page of the CG is writeable by the chairs.  Should see what other groups do.
16:45:38 <dbooth> ACTION: DBooth to look into doing that on ouir CG page.
16:45:55 <dbooth> Topic: DICOM
16:46:55 <dbooth> erich: I've been on hold.  Two months ago I rescanned immaging data commons, and put it into RDF w the extra things we discussed, including CDT.  If anyone wants to look it's here: https://vulcan.bmi.stonybrook.edu/dcm2rdf/
16:47:01 <dbooth> ... I'll have more time in Jan.
16:47:52 <dbooth> detlef: Also int in comparing qlever.
16:48:14 <dbooth> erich: I plan to have it loaded by end of Jan.
16:48:26 <dbooth> detlef: Excellent timing.
16:49:07 <dbooth> .. Plan to try it with the new DICOM rep.
16:52:55 <dbooth> i/Attribution for our work/ACTION: Ken to draft an issue of use case for extending the FHIR ont, by Dec 18
16:54:01 <dbooth> Present: David Booth, Eric Jahn, Erich Bremer, EricP, Detlef Grittner, Ken Lord
16:54:14 <dbooth> Topic: Holidays
16:54:27 <dbooth> dbooth: We will cancel meetings on Dec 25 and Jan 1.
