DICOM -- private elements
erich: Testing on ICD -- Imaging Data Commons, 90TB of data
… ptags option (for issue 145) removes bnode linking.
(Erich shows example)
detlef: That looks sufficient for query
dcm:hasPrivateElement [ dcm:group "0019";
dcm:hasElement [ dcm:InlineBinary ""^^xsd:base64Binary;
dcm:id "96";
dcm:vr "UN"
];
dcm:hasElement [ dcm:InlineBinary ""^^xsd:base64Binary;
dcm:id "B0";
dcm:vr "UN"
dcm:hasPrivateCreatorId "SIEMENS CT VA0 COAD"
]; ];
]]: You should add the private creator ID, to enable round-tripping.

erich: the properties can be both as number or as names:
dcm:Modality "CT"; dcm:00080060 "CT"
erich: I used owl:sameAs between them
detlef: suggest using equivalentProperty instead
dbooth: agree. owlSameAs could cause problems with distinguishing them.
erich: I'm also catching invalid empty VR tm (time value) and marking them as invalid in the RDF
… 2276: (0018,1200) DS #0 [] DateOfLastCalibration
… Jena riot detected the invalid value.
… Good use case for SHACL to validate things in DICOM.
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.
… That mapping is part of the DICOM spec.
… I drafted the DICOM paper that covers the work so far. Want your review.
… Hannah Bath (QLevr author) has her own DICOM model.
… She called our "unclean"
… Want to remove the inline binaries and see if the data loads faster.
… I'll publish a new version w these changes.
… Then benchmark qlevr against virtuoso.
… starting w load times, though query times also matter.
detlef: I prefer the tags rather than the names. They're usually shorter.
erich: I'll try it.
detlef: I'll try your code.
erich: I also want to try geosparql queries.
erich: Next step is to get the paper done. That will advertise it, and get more input. Then see if DICOM is interested.
FHIR RDF R5
detlef: Colleague of mine is very unhappy with it.
dbooth: Please capture that feedback our issues list so that we can address it.
