15:04:39 <dbooth> Topic: DICOM
15:04:43 <dbooth> Meeting: FHIR RDF
15:04:46 <dbooth> Chair: David Booth
15:04:57 <dbooth> erich: My homework: https://github.com/ebremer/hcls-fhir-rdf/blob/gh-pages/dicomVR2XSD.md
15:05:21 <dbooth> Topic: Concept IRIs
15:05:48 <dbooth> gaurav: No movement yet on HL7 PR.
15:06:17 <dbooth> ... We cannot update Naming System properly, because that's not yet in THO.  But we can update just the code system, so to push through changes
15:06:50 <dbooth> ... We could start putting prefixes onto code systems (instead of naming systems).
15:07:15 <dbooth> ... We could then make sure our code works w code systems.
15:07:56 <dbooth> dbooth: Sounds good to me.
15:08:32 <dbooth> eric: Wouldn't be painting ourselves into a corner?
15:09:03 <dbooth> gaurav: I don't think so.  We can do one but have to do the naming system later.
15:09:30 <dbooth> ... My understanding is that a code system has an explicit list of codes.
15:09:56 <dbooth> ... But Naming System is broader.  E.g., US passport holders would be a Naming System because it's continuously changing.
15:10:53 <dbooth> gaurav: Also looking for other candidates for what to target next.  Radlex publishes an OWL ont w resource URLs.
15:11:16 <dbooth> ... To what extent should we push them?  It's their official OWL file.
15:13:03 <dbooth> dbooth: I would view the OWL files as defacto spec for the IRI stem.  If they later give better documentation, then we can use point to the new doc instead.
15:14:21 <dbooth> Topic: DICOM
15:19:17 <dbooth> erich: The DICOM JSON has a datatype that won't necessarily work: SV is "Signed binary integer 64 bits long" but JSON wouldn't be able to handle it.
15:20:22 <dbooth> erich: In DICOM we only need a dicom:null, not null flavors.
15:23:02 <dbooth> detlef's post: https://lists.w3.org/Archives/Public/public-semweb-lifesci/2024Jun/0003.html
15:31:22 <dbooth> dbooth: So we need an option 5a, which is the same as option 5, but using dicom:null instead of fhir:null .
15:33:20 <dbooth> eric: Sentinal + xsd need to give us round tripping.
15:39:20 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/141
15:41:06 <dbooth> AGREED: Go with option 5a (to change fhir:null to dicom:null), but still discussing whether/how to represent the VR in an XSD datatype.
