ACTION: DBooth to draft ballot comments for Rob Hausam

Scripts to convert FHIR RDF to ontology friendly RDF

eric: Don't want to reinvent all of R4 RDF. We only want to add indexes.

dbooth: Another possibility would be to gen R4 RDF

eric: But that would be harder, because we'd have to fully qualify all the property names -- we'd have to know all of them.

dbooth: We'd have to generate a big lookup table of everything in the hierarchy.

option 1: add explicit indexes without changing property names

option: Generate R4, which has explicit indexes and fully qualified property names

option 3: Change the rdf: namespace of the of the list predicates to nonRdf: namespace.

eric: Options 1 and 2 will help SPARQL users, but not option 3.

dbooth: I'd like to help both SPARQL and OWL users with the same generator.

eric: What's good for OWL is not necessarily the same as what's good for SPARQL.

dbooth: How much do we care about generating an explicit index for SPARQL users?

eric: Most users who care about the order of items in a list will want the first element, which is easy to get with SPARQL without an explicit index.

AGREED: We don't need to gen an explicit index

gaurav: Should we document the nonRdf: namespace?

dbooth: We could, to make it standard.

gaurav: Like the idea of making it dereferenceable to an explanation.

gaurav: Could use figshare for the document

jim: Could use a w3id

dbooth: Or it could go to the FHIR rdf.html page, as an anchor

dbooth: Preferences?

jim: w3id or github

gaurav: figshare or github

eric: rdf.html

houcemeddine: Suggest w3id, https://purl.archive.org/

dbooth: Could use the fhir: namespace

jim: Could do fhir:rdfFirst and fhir:rdfRest

dbooth: Or fhir:f and fhir:r

AGREED: Use the fhir: namesAPCE

AGREED: Use fhir:rdfFirst and fhir:rdfRest for OWL-friendly lists.

eric: What about literals?

jim: For literals we could use fhir:rdfFirstLiteral

AGREED: Use fhir:rdfFirstLiteral for literal predicate

eric: Only care about literals if you're using a list and wanto to preserve order and you're doing a logical model that has those.

ACTION: Jim to propose SPARQL to for list conversion

Concept IRIs

gaurav: Hope to have something to share by next Thursday
