15:00:29 <dbooth> rrsagent, make logs public
15:01:22 <dbooth> Meeting: FHIR RDF
15:02:19 <dbooth> Chair: David Booth
15:07:02 <dbooth> Topic: Turtle parser/serializer
15:08:23 <dbooth> tim: Next I want to work on converting strings to booleans, but need a quicker way to test.
15:11:56 <dbooth> dbooth: Can meet right after this call, with Deepak, to discuss.
15:12:43 <dbooth> ... Any other questions about what should be done?
15:14:21 <dbooth> eric: Root nodes in R5 are now bnodes instead of IRIs.
15:15:01 <dbooth> jim: I think it was because in R4 it had BASE setting.
15:17:22 <dbooth> dbooth: Wny would lack of explicit BASE prevent it from getting an IRI?  Wouldn't a default BASE be used?
15:17:55 <dbooth> eric: In theory yes, but if nothing sets the default base then the code does a bnode.

15:22:55 <dbooth> dbooth: Any questions about how this should be handled?
15:23:43 <dbooth> jim: I have a SPARQL tool to skolemize all blank nodes into IRIs using UUIDs.
15:24:22 <dbooth> ... I'd like to incorporate that if we continue in this direction?
15:25:00 <dbooth> eric: If you can emulate Harold's SNOMED example, that would be good.  I was planning on showing something like that at AMIA.
15:25:31 <dbooth> ... Need to have 3.5 hour video recorded by the 27th.
15:26:07 <dbooth> dbooth: Is it clear that we'd like to gen IRIs if we can?
15:26:17 <dbooth> jim: Yes, though if we skolemize it doesn't matter so much.
15:26:30 <dbooth> eric: These should be named nodes, because the REST API allows you to address them.
15:26:47 <dbooth> ... Want to encourage people to  do that.
15:27:53 <dbooth> dbooth: Will there be an issue of where the examples are hosted vs where the base needs to be?
15:28:05 <dbooth> eric: No, because they're all broken already.
15:28:25 <dbooth> ... Would be great to fix this in the publication spec anyway, but reluctant to attack it.
15:29:43 <dbooth> dbooth: Should we show the BASE in the example?
15:31:29 <dbooth> eric: Not helpful.  Base statement would have to be changed when you move the data, and a base comment would be more likely to cause confustion than help.
15:33:23 <dbooth> Topic: Concept IRIs
15:34:31 <dbooth> gaurav: CURIES have a prefix in the code.   Wikidata has this same problem.
15:34:48 <dbooth> ... Joe Flack from TIMS contacted me.  They're trying to figure out what to do.
15:36:17 <dbooth> ... He added a couple of proposals.
15:36:34 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/127
15:39:39 <dbooth> eric: Nothing says the code will be unique across all code systems.
15:40:18 <dbooth> gaurav: I recommend only having the code - -no prefix.
15:41:42 <dbooth> eric: I think stripping out the prefix effectively creates a comment field.
15:44:09 <dbooth> jim: If we allow CURIEs then we don't need system at all.
15:45:21 <dbooth> jim: Suggest we say that you can't put CURIE in a code field.  You need to use only the code.
15:45:38 <dbooth> AGREED: you can't put CURIE in a code field.  You need to use only the code.

15:49:33 <dbooth> ACTION:  DBooth to create jira ticket to add this clarification to rdf.html page
15:54:19 <dbooth> ACTION: Eric to reach out to CSIRO group about CURIES and our FHIR RDF decision
15:55:07 <dbooth> gaurav: Will this affect their triples?
15:55:18 <dbooth> jim: Those are hard coded to use the right RDF namespace.
15:55:50 <dbooth> tim: Is that because someone is putting it into the system and code, but need a process to turn it into RDF links.
15:56:27 <dbooth> jim: Ideally there should be code that pulls the IRI stem and converts the JSON to FHIR RDF using them.
15:57:44 <dbooth> Topic: Jira issues
15:58:13 <dbooth> gaurav: Currently need to login to gitlab.  But cannot edit a file.
15:58:30 <dbooth> ... Cannot open in web UID.
15:58:42 <dbooth> rob: I always do it in a local copy.
15:59:01 <dbooth> gaurav: I tried pushing changes, but it says I don't have permission.
15:59:40 <dbooth> rob: They make a new supposedly simpler procedure.  Ask Jessica Bota how to do it.
