OIDs of the CodeSystems can be found within the JSON/XML. Does this suffice?

I agree - OID is required to support v2 and v3 applications communicating with FHIR applications.

CodeSystem OID stil required to support existing applications using various HL7 standards (v2, v3, CDA). Also required to support applications in the context of IHE profiles using OID.

I believe these 3 are still essential, the only argument is version might not be useful in situations where there is a live update rather than batch update but that is minor.

Hello,

At a past HL7 Community call, there was a suggestion to have the Terminology Gateway display the CodeSystem OID along with the CodeSystem URI. Currently, information regarding a subset is tabulated with the following:

1. Name of CodeSystem
2. URI of Codesystem
3. Version

Just wanted to seek the community's feedback on whether there is any impact to usage and if it indeed warrants a change.

Any thoughts or suggestions are welcome.
