16:02:15 <dbooth> rrsagent, make logs public
16:03:11 <dbooth> Meeting: FHIR RDF
16:04:26 <dbooth> Topic: Issue 146
16:04:45 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/146
16:16:49 <dbooth> erich: It would need the SOP instance ID to make a reusable URI for it
16:26:15 <dbooth> detlef: http://semantic-dicom.org/dcm#StructureSetROISequenceItem_99999.70989091007225463773458855903144372742_30060080.1
16:26:39 <dbooth> s/http/An example: http/
16:29:21 <dbooth> erich: Maybe could use <urn:oid:somethingrandom/dcm:30060080>
16:31:48 <dbooth> Maybe use a relative URI like: Maybe relative URI like: <dcm:30060080/0>
16:34:30 <dbooth> erich: That's similar to my suggestion after it is expanded w the base URI
16:34:33 <dbooth> dbooth: Yes.
16:41:19 <dbooth> eric: Or we could go with a simpler solution that would allow users to choose their own URI namespace for it, which would not guarantee that indpendent users would detect the same object.
16:51:04 <dbooth> dbooth: If you use bnodes, then RDF cannot link them automatically even though, using DICOM knowledge, two bnodes are intended to represent the same thing.
16:53:28 <dbooth> ACTION: Erich to try this in his converter, w URN
16:54:36 <dbooth> erich: I'm also working on a SHACL representation of DICOM
17:01:29 <dbooth> dbooth: Relative URIs only exist at the syntactic level, for example in Turtle.  RDF itself has no notion of relative URIs.  They are immediately converted to absolute URIs (using whatever  base URI is currently applicable) when a Turtle document is loaded into a triple store.
17:03:36 <dbooth> dbooth: In summary, if we leave those list item identifiers as bnodes, then  two independent users who load the same file and understand DICOM could infer that those two first items in that list are actually the same thing, but the triplestore would not know to join them for you automatically.

17:12:35 <RRSAgent> I have made the request to generate https://www.w3.org/2025/01/16-hcls-minutes.html dbooth
17:13:54 <dbooth> i/erich: Maybe could us/(Discussing the bnode object in the list in the example Erich provided at the beginning of issue 146.)
