Meeting minutes

Playground

eric: There are still context files in there, but they are not being used.

FHIR build -- Templates and Examples

dbooth: done?

jim: One little thing: need to fix the multi-line comment problem.
… The PRs are open. The tests pass on some architectures.
… They have a CI workflow.

dbooth: Should get them merged ASAP.

ACTION: Jim to get the PRs merged.

daniel: Use examples to check the ont?

dbooth: Yes, excellent idea.

dbooth: Daniel, Jim may be able to help answer your protege or OWL quetsions.

eric: Everything should have a type arc.

jim: Some things don't. The top level objects do, and the value[x] properties do.

eric: Can load FHIR resoruces and see if there's anything without a type arc.

ACTION: Jim to help Daniel to test the ont

Ontology

Daniel: minCardinality is formatted as binary string instead of toString.

AGREED: fix it.

Daniel: Also there is case "if (min > 1)
… That I think should be "if (min >= 1)".

jim: For cardinality 1, it's better to use someValuesFrom. But also include the allValuesFrom

jim: Another issue: don't put all those properties on the same blank node.

ACTION: Jim to work w Daniel to gen the right OWL assertions.

daniel: Also an issue of fhir:integer64 where it should be xsd:integer

dbooth: The highlighted fhir:integer64 is supposed to be xsd:integer

daniel: My issue 4, cardinality assertions are being put on the same blank node.

ACTION: Jim to help Daniel straighten that out.

jim: It was generating fewer errors before only because it was barfing on the syntax.

eric: You could comment it out if you cannot meet the deadline.

daniel: My issue 4b, qualified cardinality.

jim: Should separately specify the type and the cardinality.

eric: I don't think the structure defs allow you to say something that would be a qualified cardinality.

daniel: So we don't need to do 4b.
… My code figures out what kinds of things can have modifier extensions.

daniel: Now going to work on my issue #2.

<Github> w3c/hcls-fhir-rdf#2 : test of issues list

dbooth: What's your PR ETA?

daniel: Hopefully by Thursday.

HAPI

eric: About to dive into HAPI code. Loaded intelliJ, but no progress yet.
… WOuld be helpful if jim could supply some R5 RDF examples.

ACTION: jim to put up a link to another build

daniel: I used the redland diff. But the python rdflib one might work better.

ShEx Generation

deepak: Will do a PR tomorrow.
