| 5 | Working with unversioned content | 15 | Proposed example: http://localhost:8080/fhir/ValueSet/$expand?url=http://snomed.info/sct/45991000052106/version/UNVERSIONED?fhir_vs=isa/27624003&designation=sv ML makes the case that unpublished content is not legitimate SNOMED and suggested using a not-SNOMED URI eg http://snomed.info/xsct/45991000052106 | |
| 6 | FHIR Server Federation | Use case for fall back lookup when server does not know the answer to any particular question eg a façade server which has knowledge of all services it could potentially delegate to. | ||
| 7 | Behaviour on Lookup | 10 | What properties are returned? Discussion: Both Ontoserver and Snowstorm are returning EffectiveTime which is not listed here (unlike other SNOMED specifics): https://build.fhir.org/snomedct.html
Point of interest: Grahame's server returns a copyright property. Update 7 April - Question about whether this is required / desirable? | |
| 8 | Language Reference Sets in FHIR | 45 | All | |
| 9 | SNOMED Family of Languages | 10 | Impact of proposed changes (eg text searching in ECL) on FHIR. Questions around which language reference sets to use when there are multiple, especially partial/overriding context (referred to MAG for discussion) | |
| 10 | SNOMED FHIR Implementation Guide | 60 | Implementation Guide for using SNOMED CT with FHIR. Update 10 Dec: DK - main problem is URI/Ls which publisher has fixed ideas about. Publisher does not examine all folders - looks in profiles but not subfolders and doesn't seem to look in ValueSet folder. Update 21 Jan: DK and RH have merged commits and these can be seen in the HL7 server build: http://build.fhir.org/ig/IHTSDO/snomed-ig/branches/new-template/ and build errors here: http://build.fhir.org/ig/IHTSDO/snomed-ig/branches/new-template/qa.html Update 11 Feb: Grahame said that he'd show us how to set the URI so that it doesn't have to follow the base URI. Next person to try that can we fire a Zulip off to ask about it?

Potential Items for Discussion
| Description | Owner | Notes & Actions | |
|---|---|---|---|
| API for FHIR Resource ↔ Post coordinated expression mapping | API for FHIR Resource to SNOMED Expression
| ||
| Looking up an SCTID in an unknown module | Problems when dependencies do not align. Multiple code system resources represent multiple editions / versions. ML: See code parameter to code system search. Should return code systems (ie versions) where that code is defined. International concepts would appear in every edition known to the server. eg /CodeSystem?system=htp://snomed.info/sct&code=12345678&_elements=version

| GPS | See Discussion on Global Patient Set (GPS) | ||
| FHIR Shorthand | Michael Lawley | https://github.com/HL7/fhir-shorthand/wiki https://build.fhir.org/ig/HL7/fhir-shorthand/FSHQuickReference.pdf Tooling: https://github.com/FHIR/sushi | |
| $lookup operation - properties returned | Peter Jordan | Using http://ontoserver.csiro.au/vstool/ I noticed that both Ontoserver and SnowStorm return a SNOMED CT $lookup property for effectiveTime, which I don't see listed, as one of the SNOMED CT properties in the FHIR R4 specification at http://hl7.org/fhir/snomedct.html. Should we create a Jira TIcket to add this? Completed - https://jira.hl7.org/browse/FHIR-26555 | |
