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