14:54:16 <dbooth> Meeting: FHIR RDF
14:54:19 <dbooth> Chair: David Booth
14:54:53 <dbooth> Regrets: Emily Pfaff, Jim Balhoff, Gopi
15:05:12 <dbooth> Topic: Issue 93: Modifier extensions (Eric)
15:15:29 <dbooth> gaurav: What is the domain of fhir:active if it is done this way?
15:15:51 <dbooth> eric: It's generally bad form in RDF to restrict the domain.
15:16:27 <dbooth> eric: you annoy developers if you reify it.
15:20:03 <dbooth> eric: You either risk the property being misinterpreted, or you move it and affect the domain, or you reify.
15:26:47 <dbooth> david: My concern is to avoid accidentally interpreting a modified property, but beyond that I think we should do the absolute minimum.
15:28:02 <dbooth> eric: don't want to force the processing of non-mod extensions to be different if there are mod extensions.
15:39:01 <dbooth> Eric proposes option 2c (in turtle origValue)
15:39:31 <dbooth> david: That looks like it would solve the problem.
15:39:43 <dbooth> gaurav: agreed.
15:40:34 <dbooth> AGREED: Provisionally go with option 2c (origValue) for modifier extension
15:41:43 <dbooth> Topic: Issue 92: Significant digits in decimal numbers
15:44:12 <dbooth> gaurav: JSON allows precision to be implementation dependent.
15:44:38 <dbooth> ... I think xsd:decimal does everything we need.
15:45:03 <dbooth> ... But there's also xsd:precisionDecimal available.
15:46:00 <dbooth> ... We cannot really do anything about the FHIR JSON part of it, except to remind people to use a special FHIR JSON parser.
15:47:43 <dbooth> gaurav: our tooling will have to turn FHIR JSON into triples.  Some JSON parsers have an option to use xsd:decimal
15:49:19 <dbooth> david: Propose that we close this with no change to R4.
15:49:43 <dbooth> AGREED: All agreed.  Close issue 92 with no change to R4.
15:50:23 <dbooth> Topic: Issue 78: Context sensitive date data types
15:50:55 <dbooth> gaurav: FHIR spec allows partial dates.  But we use xsd:datetimes, and that does not allow approximate dates.
15:52:35 <dbooth> gaurav: XSD has various date types available for the different varieties.  The JSON-->RDF conversion could look at which kind is needed and apply it.
15:53:59 <dbooth> gaurav: We could include both  xsd:datetime and a less specific type, such as xsd:gYearMonth .
15:55:01 <dbooth> gaurav: But that would add redundancy.  Prefer thatwe just use one datatype, such as xsd:gYearMonth
15:55:25 <dbooth> eric: I think that's what we have in R4 now.
15:57:06 <dbooth> Proposal to close 78 with no changes to R4.
15:57:14 <dbooth> AGREED: Unanimous.
16:30:22 <dbooth> s/Unanimous/ close 78 with no changes to R4
