Meeting minutes

Drug ID ontology

DBooth: Will follow up with Heiner about scheduling this

Turtle examples

tim: Sent PR and mentioned it zulip.

eric: That will allow us to test shex better.

ACTION: tim to ping grahame on zulip

tim: the other changes i have add things that make it easier to gen all the exapmles without genning the entire FHIR spec.

tim: "I made some progress towards adding extra unit tests for generating examples tmprd/org.hl7.fhir.core#1 "

eric: Could put them on github so I can grab them.
… I'll give you permission to put in in fhircat repo

http://github.com/fhircat/ShExValidation

dbooth: Will these changes fix all known issues in the Turtle examples?

tim: Fixes missing datatype annotations, duplication of root properties. I loaded a lot of these w protege and it told me a lot were not correct. Also there was an issue w URLs having bad chars.
… Some have a vertical bar in them.

tim: Current fixes lined up HL7/kindling#148
w3c/hcls-fhir-rdf#120

https://chat.fhir.org/#narrow/stream/179177-conformance/topic/syntax.20of.20Reference.2Ereference.20with.20version

eric: Does FHIR protocal accept accepts the percent-encoded vertical bar in a request?

rob; Depends on how the operation is defined.
… If' it's looking for a URI you have to strip it out.

eric: canonical: http://example.org/fhir/questionnaire/patient-intake|1

encoded: http://example.org/fhir/questionnaire/patient-intake%7C1

REST API: http://example.org/fhir/questionnaire/patient-intake?version=1

ACTION: Eric to follow up on the zulip thread

Imaging metadata

erich: Also similar to features pulled from deep learning pipelines. How far does FHIR go to having vocab to describe them?
… Geo groups say it doesn't need to be limited to geo.
… Dicom has a lot of vocab for radiology images, and now has pathol vocab. Recently added annotation capabilities. But there's no official RDF casting to it.
… Which group handles this, and how do i connect it to FHIR RDF data?

rob: in RDF, no clear answer. Between imaging WG and FHIR infra and this group, we'll need to figure it out. Not sure anybody's explored it.

erich: Can do demo in a few weeks.

tim: Have you seen the imaging study resource, and how it connects to DICOM?

erich: Not yet.

https://www.hl7.org/fhir/imagingstudy.html

erich: Some casting from DICOM to RDF have been done, but nothing official. Seems like an opportunity.

dbooth: identified others with similar interest?

erich: OMOP group is interested, but again no official RDF casting.

eric: Where do you want to go?

erich: Based on problems I need to solve.
… Want to base it on standard where possible.

eric: if you ask how to connect to external resources, the FHIR folks will say "let's make FHIR resources for it"
… There's bound to be a boundary on that. Better to have DICOM on the inside or the outside of that boundary?

eric: There will be a swat4ls conference in a couple months. Scott Marshall will be there. Maybe get together there? Maybe push the DICOM people to annoint?

eric: Seems like we need an annointed DICOM RDF

ACTION: EricP to ping Scott Marshall about DICOM RDF

tim: Laterality refers to DICOM. Maybe make an extension of the ImagingStudy resource?

eric: If we already know how to connect the two ontologies, then in theory we can do what we need. FHIR Extensions are not very friendly to RDF use.
