15:02:37 <dbooth> Meeting: FHIR RDF
15:02:57 <dbooth> Topic: DICOM
15:03:00 <dbooth> s/DICOM/DICOM -- private elements
15:03:43 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/145
15:06:03 <dbooth> erich: Testing on ICD -- Imaging Data Commons, 90TB of data
15:07:27 <dbooth> ... ptags option (for issue 145) removes bnode linking.
15:11:18 <dbooth> (Erich shows example)
15:11:27 <dbooth> detlef: That looks sufficient for query

15:14:23 <dbooth> detlef: You should add the private creator ID, to enable round-tripping.

15:22:12 <dbooth> s/eric:/erich:/
15:23:04 <dbooth> erich: I used owl:sameAs between them
15:23:52 <dbooth> detlef: suggest using equivalentProperty instead
15:25:27 <dbooth> dbooth: agree.  owlSameAs could cause problems with distinguishing them.
15:27:31 <dbooth> erich: I'm also catching invalid empty VR tm (time value) and marking them as invalid in the RDF
15:28:08 <dbooth> ... 2276: (0018,1200) DS #0 [] DateOfLastCalibration
15:28:23 <dbooth> ... Jena riot detected the invalid value.
15:29:32 <dbooth> ... Good use case for SHACL to validate things in DICOM.
15:30:41 <dbooth> erich: The little bit of DICOM that is RDF, want to use my DICOM-to-SHACL to tease out the keywords and rules.  Want to handle that keywords set to map those terms to URIs.
15:31:08 <dbooth> ... That mapping is part of the DICOM spec.
15:31:37 <dbooth> ... I drafted the DICOM paper that covers the work so far.  Want your review.
15:32:58 <dbooth> ... Hannah Bath (QLevr author) has her own DICOM model.
15:33:07 <dbooth> ... She called our "unclean"
15:33:34 <dbooth> ... Want to remove the inline binaries and see if the data loads faster.
15:34:05 <dbooth> ... I'll publish a new version w these changes.
15:34:54 <dbooth> ... Then benchmark qlevr against virtuoso.
15:35:27 <dbooth> ... starting w load times, though query times also matter.
15:36:07 <dbooth> detlef: I prefer the tags rather than the names.  They're usually shorter.
15:36:24 <dbooth> erich: I'll try it.
15:39:00 <dbooth> detlef: I'll try it.
15:39:16 <dbooth> s/it/your code/
15:40:04 <dbooth> erich: I also want to try geosparql queries.
15:42:03 <dbooth> erich: Next step is to get the paper done.  That will advertise it, and get more input.  Then see if DICOM is interested.
15:42:37 <dbooth> Topic: FHIR RDF R5
15:42:52 <dbooth> detlef: Colleague of mine is very unhappy with it.
15:44:11 <dbooth> dbooth: Please capture that feedback so that we can address it.
