15:55:55 <dbooth> Meeting: FHIR RDF
15:55:58 <dbooth> Chair: David Booth
16:03:15 <dbooth> Topic: Concept IRIs
16:04:18 <dbooth> gaurav: Made a punch list for me: https://github.com/w3c/hcls-fhir-rdf/issues/160
16:04:25 <dbooth> ... On vac the next 2 weeks.
16:09:35 <dbooth> Topic: DICOM
16:10:49 <dbooth> erich: RFC 8141 introduces extra components to URNs
16:10:50 <dbooth> https://datatracker.ietf.org/doc/html/rfc8141#section-2
16:12:14 <dbooth> erich: If you add a frag ID to the URN, then you aren't squatting on someone else's namespace.
16:12:45 <dbooth> ... How to refer to subportions of files?   DICOM is a container format, and we want to to refer to a subsection.
16:24:46 <dbooth> eric: The frag ID can also just provide additional info, not necessarily related to the URI on which it is affixed.
16:25:18 <dbooth> dbooth: Media type seems to own the frag ID interpretation
16:27:16 <dbooth> erich: Should get DICOM's buy-in to treat the frag ID  as identifying a portion of the DICOM file
16:27:44 <dbooth> eric: Media type is used for both semantics and format.  The pluses try to make that less painful.
16:28:21 <dbooth> ... If we're trying to identify the 5th item of list 7, that's applicable to more than just RDF.
16:30:02 <dbooth> https://dicom.nema.org/medical/dicom/current/output/chtml/part18/sect_8.7.3.5.html
16:32:59 <dbooth> https://www.iana.org/assignments/media-types/application/dicom+json
16:33:40 <dbooth> dbooth: DICOM media registration does not specify frag ID semantics: https://www.iana.org/assignments/media-types/application/dicom+json
16:34:08 <dbooth> ... Can propose it to the DICOM folks when we propose the rest.
16:34:27 <dbooth> detlef: Would this allow us to identify any attribute in DICOM?
16:34:37 <dbooth> eric: Like JSON path
16:35:19 <dbooth> ... Suppose you have a JSON path in JSON-LD, then that would effectively give you a URI for it, instead of just a bnode.
16:43:07 <dbooth> erich: The problem we want to solve is to have an identifier for each element of a list.
16:47:01 <dbooth> ... I want to talk w DICOm folks soon, bc they want to be involved.

16:49:57 <RRSAgent> I have made the request to generate https://www.w3.org/2025/02/20-hcls-minutes.html dbooth
16:51:56 <dbooth> dbooth: specifically suggest using JSON path in the frag ID?
16:52:34 <dbooth> AGREED: suggest using JSON path in the frag ID
