Meeting minutes

RDF Lists #76

<Github> https://github.com/w3c/hcls-fhir-rdf/issues/76 : How should list ordering be preserved in R5?

dbooth: Preferences on RDF lists?

houcemeddine: No opinion.

jim: Keep R4 for OWL compatibility.

gaurav: Keep R4

eric: Pref RDF lists, and use a transformation for OWL folks.

dbooth: R4

eric: R4 would complicate shex.

rob: Pref RDF lists.

eric: narrative.div has a direct string value, not an object.

dbooth: example: fhir:div "<div>…</div>"

dbooth: I view that as a bug. It should be an object, to avoid potential OWL clash of ddatatype vs object property

ISSUE: Should narrative.div be an object property or datatype property?

rob; Willing to be persuaded .. . . (lost him)

gaurav: I could live with either option, so I don't feel strongly one way or another.

eric: Worried about deviating from the model.

rob: why?

eric: Because you can't have a fhir:index list if you have a list of scalars directly.

dbooth: Views?

rob: RDF lists

gaurav: Either option

houcemeddine; Either

jim: Both fine for me.

AGREED: Adopt RDF lists

Should FHIR datatype values have an rdf:type? #106

<Github> https://github.com/w3c/hcls-fhir-rdf/issues/106 : Should FHIR datatype values have an rdf:type?

dbooth: I think it's too late to consider for this R5 ballot

eric: explicit is nice, but terse is nice also.

AGREED: Table this for the moment.

Modifier extensions #93

<Github> https://github.com/w3c/hcls-fhir-rdf/issues/93 : How should modifier extensions be handled in R5?

dbooth: opinions?

rob: somewhat persuaded by option 6

jim: option 6

houcemeddine: option 6

gaurav: option 6. FHIR validator is ridiculously specific about validating all modifier fields. Not sure how we'll replicate that.

eric: option 6.

dbooth: ok w option 6

AGREED: Go with option 6.

eric: I'm editing things at https://w3c.github.io/hcls-fhir-rdf/spec/v2

dbooth: things to vote tomorrow:

1. Shortening property names

2. RDF Lists #76

3. Modifier extensions #93

4. Concept IRI

5. fhir:v
