Topic: CodeSystem.url - resolves to which FHIR version?
Paul Lynch (Jan 12 2021 at 18:15):
The description for CodeSystem.url says, "SHOULD be a literal address at which at which an authoritative instance of this code system is (or will be) published". If you fetch the resource from that literal address, which version of FHIR should you expect for the returned resource?

In theory, you can request a specific version using the 'Accept' header and standard content negotiation

If the endpoint doesn't support that, then who knows
Lloyd McKenzie (Jan 12 2021 at 18:36):
However, given the reality of most implementation, you're pretty safe presuming R4-conformant

For now...
Paul Lynch (Jan 12 2021 at 18:45):
I suppose the CodeSystem could also indicate which version it is using meta.profile. (https://www.hl7.org/fhir/versioning.html#mp-version)

Forever more - because CodeSystem is normative
