Should a change to meta.security impact meta.lastUpdated? https://hl7.org/fhir/R4/resource.html#Meta
David Pyke (Mar 23 2022 at 17:13):
That's really a policy decision.
John Moehrke (Mar 23 2022 at 18:03):
There are clearly times at which the meta should be treated like any other element, but there are other times where the updates are special cases. But any special cases would need to be identified as policy choice. Such a special case is a data tagging operation that is just tagging data (might be profile tagging, security tagging, or other tagging).
John Moehrke (Mar 23 2022 at 18:17):
There was some early discussion that the $meta operations would explicitly not change lastUpdated. I argued that might be a way to implement policy, but that FHIR core should still not define even that policy.
Lloyd McKenzie (Mar 23 2022 at 21:37):
We used to have a mechanism to modify tags without creating a new history version - and even be able to change tags on historical versions. This ability was removed in R4 because no-one had actually implemented it.
Brian Postlethwaite (Apr 12 2022 at 01:39):
There is nothing in the $meta-add/$meta-delete that indicates if new versions are created or not.
(I do note that the version specific context for calling the operations has been removed in R4 as you noted)
