Meeting minutes
Vacation
erich: On vac tomorrow through Aug 20.
IRI stems
gaurav: On UP 465, they want s/MUST/SHALL/. I made the change and it's now in their hands.
… I'm now working on next proposal, with 4 changes.
FHIR RDF examples
jim: Made a couple more changes to issue 120 also. Started outputting IDs has hash relative IRIs.
… Now working on the harder part for swapping in the IRIs for the contained parts.
jim: I looked at the RDF-star for annotating a triple, in turtle it will gen a bnode with a reified triple. Or you can provide an ID for a generated node, you can. Uses a tilde thing on the bracket syntax.
ACTION: EricP to mention to RDF-star group that bracket-equals would align better w N3 than tilde.
jim: Why change the model, for RDF-star annotation. Seems the same as the old reifications.
ericP: Their canonical exsmple was "Bob works for IBM", and annotate it w "in 2002".
jim: There's a proposal for composite data types,
erich: It caters to single dimension lists and hashes, but could be extended to multi-D arrays.
… CDT allows you to SPARQL over that data.
ericP: It allows you to create new data types.
… Whereas if there were a first-class list object in RDF, then you could do it.
HAPI
ericP: Haven't gotten to it yet. Still working on fhir:l. Did shex generator. EricP: Started AMIA demonstrator, but got hung up on packaging issues.
ericP: I think code system is a URL. THat could also have a fhir:l. Right now canonical extends URI, and URL extends URI. And we put special rules on canonical to add fhir:l, but we could change it to any place you see a URI.
jim: That's what I did.
… Here's an example: https://
ericP: I tried to get deepak to make a small version of FHIR that covers most of the def of structure def, e.g., 5 resources withh most of the properties, having all of the language features.
dbooth: Only sustainable if it is auto-generated.
ericP: Or the code could throw an error if there's a new feature found.
ericP: Would be nice to have an auto generated list of IRI stems, produced from the terminology server.
gaurav: We have a script that generates an expanded version of this.
dbooth: What about a github action in our repo, to pull from THO and gen the list?
gaurav: But it would miss the ones that are in flight (i.e., not yet in THO, but going through the process)
… Concern about github action is that UTG repo is quite big.
… Start w a manual markdown version.
ACTION: Gaurav to make a markdown page
