SI Business + Expo October
|4||COVID coding guide||25||Linda Bird|
Linda has done a comparison of SI vs HL7 ValueSets see https://docs.google.com/spreadsheets/d/1P3DgnLOvr31H4cIfRa_cTfkdhBCC8acTzPCbHmjakrI/edit?usp=sharing
Snomed on FHIR Analysis: COVID-19 Symptoms Present
|5||Working with unversioned content||15|
ML makes the case that unpublished content is not legitimate SNOMED and suggested using a not-SNOMED URI eg http://snomed.info/xsct/45991000052106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|
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|
|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.
|GPS||See Discussion on Global Patient Set (GPS)|
|FHIR Shorthand||Michael Lawley|
|$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
