Currently FOLDERS need to be referenced by an EHR with a 0..1 relationship.
In use cases such as HiGHmed and LHS-Norway patients need to be grouped in cohorts that are assigned to a specific research study. For this FOLDERs need to contain EHRs and not the other way around. Therefore a FOLDER may "contain" (i.e. reference via object_ref) many EHRs.
We need to determine if the RM should be modified for allowing independent FOLDERs to be created without belonging to a EHR or define a separate class that allows for doing so.
HiGHmed & LHS Norway
FOLDERs are part EHR, so as you mentioned it will not work. Is it perhaps an options the newly discussed TAGs (RM 1.2.0) that would point to FOLDERs ?
