15:01:47 <dbooth> Topic: DICOM
15:02:15 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/145
15:06:03 <dbooth> erich: I implemented bnodes for the dcm:hasPrivateCreatorId
15:11:32 <dbooth> (erich showed his screen)
15:11:43 <dbooth> detlef: That doesn't look entirely correct.
15:34:31 <dbooth> ACTION: Erich to rework his code
15:39:00 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/162
15:39:31 <dbooth> erich: This is a conversationi placeholder.  How should this data look in a SOLID pod?
15:39:59 <dbooth> eric: Janeiro Digital did a project putting FHIR in a SOLID pod.
15:40:51 <dbooth> ... We put FHIR data into pods, and other heath data into pods.
15:41:34 <dbooth> ... Solid application interoperability (SAI) app store on android.  App store would have resource trees that associated a dir to a shex schema.
15:41:58 <dbooth> ... That allowed you to find the file.
15:42:16 <dbooth> ... We extended that.  We never dealt w imaging.
15:42:28 <dbooth> ... If we had a FHIR resource we'd shove it in there.
15:43:11 <dbooth> ... Also: TermInfo problem.  In terminologies, you have varying levels of detail.  SNOMED has a compoitional grammar and precoordinated terms.
15:43:32 <dbooth> ... Therefore even if you had a code, it could have laterality, severity, body site, etc. all packaged into one code.
15:44:16 <dbooth> ... One code saying 3 out of 4 allergic reactions.  In other words, it has things that would not normally be in the observation.
15:44:23 <dbooth> ... How can you uniformly query that?
15:45:19 <dbooth> ... Do you make your queries really smart?  Or do you normalize the data on ingestion?
15:45:45 <dbooth> ... Some of the DICOM extensions are for diagnostic info, right?
15:46:29 <dbooth> detlef: yes
15:48:32 <dbooth> erich: I'm int in pathology whole slide imaging.  They need to be loaded, managed, marked up for deep learning pipelines.
15:48:44 <dbooth> ... Calculated polygons overlaid
15:49:04 <dbooth> ... System I'm building is RDF-based.  Started aligning to SOLID.
15:49:18 <dbooth> ... Need to load DICOM images and metadata.
15:50:00 <dbooth> ... How can SOLID pod extend the metadata?
15:50:19 <dbooth> eric: Metadata would be markup of regions?  erich: Yes.
15:51:30 <dbooth> erich: Howshould this look in the POD?  I'm usng geosparql feature groups for polygons, annotated w SNOMED URIs.
15:51:54 <dbooth> ... Want to know pixel width and height are, tile sizes, micros per pixel (for scaling).
15:52:08 <dbooth> eric: Do you want that on a HEAD request or a GET?
15:52:40 <dbooth> erich: The pathology files are huge.  You're not going to dowload the entire thing.
15:53:18 <dbooth> ... I want to extend metadata to select deeper into the files.
15:53:52 <dbooth> ... Want to expose that metadata
15:54:44 <dbooth> eric: You make every dir have a catalog.ttl w metadata, but nobody would find thier way back from the resource to that catalog.
15:55:43 <dbooth> erich: I could show folks what I've made, and get feedback.
15:59:18 <dbooth> Topic: Next meeting
16:00:41 <dbooth> ACTION: Erich to show his work next week
