16:07:43 <dbooth> Topic: Third panel of FHIR JSON-LD playground
16:09:10 <dbooth> (James gives us a demo)
16:10:58 <dbooth> james: Currently generates nquads, but will add in Turtle
16:11:10 <dbooth> james: IDK what the Framed tab does.
16:15:50 <dbooth> eric: It adds another input text box for the framing.
16:17:18 <dbooth> eric: Our narrative is to add a third window BEFORE the first JSON-LD playground window.
16:22:30 <dbooth> david: the options that eric is add should be applicable between the first and second windows.
16:24:11 <dbooth> eric: The "framed" button should move the middle window to the left and add the framing window next to it.
16:26:39 <dbooth> james: Did you create that turtle processor?
16:26:47 <dbooth> eric: Yes, basically.
16:26:54 <dbooth> s/processor/serializer/
16:27:17 <dbooth> ... I used shex validation to order the triples.
16:28:27 <dbooth> Topic: RDF lists
16:28:54 <dbooth> jim: I've collected previous discussions, going back to work on OWL2.
16:29:31 <dbooth> ... Feeling pessimistic.  OWL experts considered the issue at the time.
16:29:52 <dbooth> ... Sometimes might want to use rdf:first as data property, sometimes as object property.
16:30:19 <dbooth> ... Maybe consider having a FHIR RDF to OWL transformation, which would only have to change the list vocabulary.
16:30:34 <dbooth> eric: That would allow you create typed lists.
16:31:14 <dbooth> ... I think it's ridiculous that we're 10 years into RDF 1.1 and we're now looking at this problem.
16:31:26 <dbooth> ... Most interesting use case for FHIR and OWL, is classification use case.
16:32:11 <dbooth> ... Harold Solbrig did a nice example.
16:32:12 <dbooth> https://yosemiteproject.org/tutorial-fhir-rdf-as-a-bridge-to-the-semantic-web-in-healthcare/
16:32:55 <dbooth> ... If you play that twice in the same data.  E.g., person record has an address with a list of contacts.
16:33:07 <dbooth> ... E.g., first address must be home address.
16:33:32 <dbooth> ... And another list that's CodeableConcept, and see if we can do in OWL what we want to do.
16:35:01 <dbooth> jim: Often in OWL reasoning, i expect some preprocessing before putting anything into a reasoner.
16:35:16 <dbooth> ... You kind of need to know all about it first, and then put in the right things.
16:36:35 <dbooth> ... Wouldn't be so bad to say that FHIR RDF needs some transformations before applying an OWL reasoner.
16:38:51 <dbooth> ACTION: Jim to start with the Harold's tutorial
16:40:49 <dbooth> Topic: Converting data to FHIR RDF
16:40:59 <dbooth> dagmar: Converting synthetic patients to RDF, trying to make them about one patient, to try SPARQL queries.  Trying to see how you can use FHIR RDF in other ways.
16:41:16 <dbooth> ... About a million synthetic patients, in HL7 FHIR JSON.
16:41:39 <dbooth> ... Analyzing how they are linked.
16:46:57 <dbooth> ADJROUNED
