dbooth: See draft: https://github.com/dbooth-boston/fhir/blob/rdf-html-page/source/rdf.html

AGREED: Change w5: prefix to fhirw5:

dbooth: Ae we now generating any OWL files other than fhir.ttl, rim.ttl and w5.ttl?

tim: Not yet.

dbooth: Ae we now generating any OWL files other than fhir.ttl, rim.ttl and w5.ttl?

tim: Not yet

dbooth: Section on semantics of hash IDs okay? See #contained section

ACTION: ericp to work w dbooth on wordsmithing

dbooth: New section on OWL, ShEx, w5 and RIM okay?

dbooth: New section on OWL, ShEx, w5 and RIM okay?

ACTION: Tim to add fhir version (semantic) and document version (as file date)

AGREED: shex and ont section is good

Issue 182: new Turtle prefixes fhirbt: and fhirdt: ?

w3c/hcls-fhir-rdf#182

w3c/hcls-fhir-rdf#182 (comment) primitive types (fhir:String vs fhirdt:string vs fhirpt:string)

tim: Capitalizing primitive types seems simpler

dbooth: Using a different namespace for all datatypes would cause complex rules to the user, of which to use.

For capitalizing: tim, jim

For different prefix: dbooth, ericp

eric: prefixes

erich, and detlef: capitalize

AGREED: Capitalize

Issue 175: FHIR profiles in OWL

w3c/hcls-fhir-rdf#175

tim: I won't be able to get this into R6

(Erich Bremer dropped)

dbooth: Should we point to a repo that we control, for latest OWL or shex versions?

tim: I found a review of the RDF page: https://ginocanessa.github.io/fmg-r6-review/its/page_rdf.html

tim: Conformance words need to be in all caps

ACTION: dbooth to look for conformance words

AGREED: dbooth to add link to build.fhir.org for latest shex and ont

HAPI

ericp: Working on it
… Latest ttl examples would be helpful

tim: Use jim's latest R6 examples: https://github.com/fhircat/org.hl7.fhir.core-turtle-examples-writer/tree/hcls-fhir-rdf-issue-121-link-diff/fhir-examples-out

Issue 190: Add fhir:link as sibling of "a fhir:Reference" assertion

ACTION: Detlef to change the primitive types to capital in kindling

tim: w3c/hcls-fhir-rdf#120 (comment)

ACTION: dbooth to move "Need for <canonical> & <CodeableReference> too" on checklist page to #177

ACTION: Tim to edit w3c/hcls-fhir-rdf#198

ACTION: fhir:div xsd:string --> rdf:XMLLiteral was already done in the examples

ACTION: dbooth to fix checklist for #187: no yellow schema change needed

AGREED: Change fhir:div to use a bnode standoff like all other primitive types, even though it is not extensible

tim: it would be simplify OWL to treat it the same as other primitive types

w3c/hcls-fhir-rdf#199
