14:57:17 <dbooth> Meeting: FHIR RDF
14:57:20 <dbooth> Chair: David Booth
15:05:17 <dbooth> Topic: Ballot comments
15:07:06 <dbooth> dbooth: comments due Oct 4.  Rob Hausam will file on our behalf.
15:07:39 <dbooth> Ballot process: http://35.190.153.146/ballot-intro.html
15:15:34 <dbooth> ACTION: DBooth to draft ballot comments for Rob Hausam
15:17:14 <dbooth> Topic: Scripts to convert FHIR RDF to ontology friendly RDF
15:17:42 <dbooth> eric: Don't want to reinvent all of R4 RDF.  We only want to add indexes.
15:18:32 <dbooth> dbooth: Another possibility would be to gen R4 RDF
15:19:02 <dbooth> 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.
15:19:43 <dbooth> dbooth: We'd have to generate a big lookup table of everything in the hierarchy.
15:22:25 <dbooth> option 1: add explicit indexes without changing property names
15:22:45 <dbooth> option: Generate R4, which has explicit indexes and fully qualified property names
15:23:13 <dbooth> option 3: Change the rdf: namespace of the of the list predicates to nonRdf: namespace.
15:24:20 <dbooth> eric: Options 1 and 2 will help SPARQL users, but not option 3.
15:26:06 <dbooth> dbooth: I'd like to help both SPARQL and OWL users with the same generator.
15:26:21 <dbooth> eric: What's good for OWL is not necessarily the same as what's good for SPARQL.
15:30:18 <dbooth> dbooth: How much do we care about generating an explicit index for SPARQL users?
15:31:29 <dbooth> 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.
15:33:06 <dbooth> AGREED: We don't need to gen an explicit index
15:34:21 <dbooth> gaurav: Should we document the nonRdf: namespace?
15:34:53 <dbooth> dbooth: We could, to make it standard.
15:35:10 <dbooth> gaurav: Like the idea of making it dereferenceable to an explanation.
15:37:22 <dbooth> gaurav: Could use figshare for the document
15:37:38 <dbooth> jim: Could use a w3id
15:38:06 <dbooth> dbooth: Or it could go to the FHIR rdf.html page, as an anchor
15:40:09 <dbooth> dbooth: Preferences?
15:40:15 <dbooth> jim: w3id or github
15:40:30 <dbooth> gaurav: figshare or github
15:41:43 <dbooth> eric: rdf.html
15:43:16 <dbooth> houcemeddine: Suggest w3id, https://purl.archive.org/
15:45:00 <dbooth> dbooth: Could use the fhir: namespace
15:45:29 <dbooth> jim: Could do fhir:rdfFirst and fhir:rdfRest
15:45:45 <dbooth> dbooth: Or fhir:f and fhir:r
15:47:33 <dbooth> AGREED: Use the fhir: namesAPCE
15:49:36 <dbooth> AGREED: Use fhir:rdfFirst and fhir:rdfRest for OWL-friendly lists.
15:52:58 <dbooth> eric: What about literals?
15:53:53 <dbooth> jim: For literals we could use fhir:rdfFirstLiteral
15:54:24 <dbooth> AGREED: Use fhir:rdfFirstLiteral for literal predicate
15:56:43 <dbooth> 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.
15:57:46 <dbooth> ACTION: Jim to propose SPARQL to for list conversion
15:59:35 <dbooth> topic: Concept IRIs
15:59:47 <dbooth> gaurav: Hope to have something to share by next Thursday
