What should a DICOM RDF file use as a primary subject?

#142

w3c/hcls-fhir-rdf#142

detlef: Suggest having instance IRI in the file.
… The DICOM dir has relative path of files.
… If we had a URI for each entity, then you can merge them easily.
… I want this ability, regardless of what we use for subject URI.

erich: I like this idea
… of the DICOM directory

ACTION: Detlef to share an example in the issue

erich: dcm3j has the ability to do the DICOM dir
… Keeping metadata on the files, what to think how to use linked web storage
… If there's a concept of a DICOM dir, it might well w linked web storage.
… When you do a GET on SOLID storage for a particular container, I see DICOM files, and I GET those
… And it could give the RDF conversion of the image as an enrichment.

ericp: You conneg to RDF

erich: If there's an official RDF DICOM representation, then linked web storage gives a way to get to it.

ACTION: Erich to look into DICOM directories

How best to represent DICOM lists with missing elements, in FHIR RDF?

#141

w3c/hcls-fhir-rdf#141

AGREED: Option 10, though we have not yet decided on namespace for dcm: prefix.

Current work as it relates to prior DICOM RDF work #143

w3c/hcls-fhir-rdf#143

erich: This is just an RDF vocabulary of DICOM terms. Just a URI space for those terms. It's still maintained.

https://dicom.nema.org/medical/dicom/current/output/chtml/part16/chapter_d.html

erich: We can close this issue with no change. No motivation for changing the namespace.

AGREED: No action needed. closing issue.

DICOM: How to handle InlineBinary and BulkDataURI?

#144

w3c/hcls-fhir-rdf#144

ACTION: Erich to look at how DICOM Web is handling this.

DICOM Private Data Elements in DICOM RDF #145

w3c/hcls-fhir-rdf#145

detlef: DICOM doesn't define how the private identifiers are assigned.

ericp: The "private creator 1" part is analogous to a URI, somehting like "IBM" or "Siemens"
… The attribute tag, like "(0027,0010)" is like a bnode.
