After discussing internally and doing some more research, we discovered that both aforementioned problems already have change requests in the CKM:
- CR-1309: FHIR supports range for administration rate submitted by @SevKohler on 11.02.2026 and already supported by @ian.mcnicoll
- CR-1161: Expand possible units of administration rate quantity submitted by Angela Merzweiler on 11.12.2024
I am not confident in the CKM workflow, but I have taken the initiative of creating a new branch to implement those changes: https://ckm.openehr.org/ckm/archetypes/1013.1.8248
I will adapt the ADL and upload the adjusted version to that branch soon, and submit it for editorial review.
While expanding the list of allowed units for CR-1161, the question of orderability came up. Ideally, the unit list would be (somewhat) sorted by unit and magnitude. However, the unit list in ADL seems to be numbered, so we assume that changing the order of that list would constitute a breaking change, which should be avoided. Thus, for now, I would add the new units at the end of the list, sacrificing order for backwards compatibility. Is our assumption correct, or could we reorder the list without inducing a breaking change to the archetype?
