Topic: Adding profile restrictions to DomainResource or Resource
Jonny Rylands (Mar 09 2016 at 12:16):
When profiling a resource (e.g. Patient), is it possible to restrict elements in the resources parents (e.g. DomainResource or Resource)?
Example, if creating a NhsPatient profile based on the Patient resource, could you add a slice to meta.profile and constrain the slice to be the URI of NhsPatient?
I note that Forge doesn't allow you to "see" the parent resource elements, but I don't know if this is just something not supported in it yet.
Many thanks.

Hi Jonny, yes FHIR allows constraints on elements inherited from Resource or DomainResource. However Forge currently does not yet display these elements. We are planning to implement support in a future release.

Great, thanks.

BTW I am aware that the NHS needs this functionality. We'll try and prioritize this change.

why is this useful? sounds like a recursive profile :) Is this for profiles on other profiles? (ie where there is a subset of UK patient??)

I'm not sure of Jonny's use case but we definitely have requirements in this area. In some places for example we may want to say "always state a profile"

You want to be able to say "instances of this profile must explicitly declare conformance with this profile" or possibly "must declare conformance with one of the following other profiles" - it's a shortcut to "including" other profiles.

@Jonny, coincidentally I managed to implement support in Forge for editing profile restrictions on common resource elements inherited from DomainResource and/or Resource (id, meta, implicitRules, language, text). This behavior is disabled by default and controlled by a new configuration setting in the Options menu ("Expand Common Elements"). If you toggle this setting the application requires a restart. You can download the new release from http://fhir.furore.com/forge. Please let me know if you have any questions or comments.

Superb! I will check it out now.
