OK Bert, let's say that an EHR system manages a graph of objects and my idea is
just a representation of such a graph.
PARTY_IDENTIFIED (Patient) - OBJECT_ID (Patient) - COMPOSITION - OBSERVATION -
FOLDER - PARTY_IDENTIFIED (Organizaion)
If you like :)
I don't get your question in the way you ask it. Let me explain it my
way, maybe it becomes clear then.
The root of an patient-EMD is the EHR (with rootfolder), and there is
the patient linked to.
If an EHR system is shared by more organizations, there share also
patients, I guess. Else I don't get the point from sharing. There is no
root where all patients/EHRs are together, so there is no organization-root.
As said, it is patient centric.
So a patient retrieves treatments, in the organizations, in the
compositions and the accompanying audit-activity is notated by whom that
specific treatment was given.
Now about the folders, there is some documentation about how to use
them, I forgot which document, but you can think of grouping
compositions which have something specific in common, for example
diabetics-related.
Beside treatments, a patient can have longer term professional
relationships with healthcare professionals, you can arrange that with
party-relationships and roles. Those information exists outside the EHR,
but is connected the the patients and healthcare professionals. See in
the demographic reference-model where you can find attributes to store
this information, in the PARTY class (base of
person(patient/healthcare-professional) and organization, I think.
I must say I do it all out of my head, I know the reference model, but I
do not know it exactly in all details.
But ask if it is not clear, maybe I know the answer, or someone else
knows it better.

I believe OpenEHR is patient-centric, and a patient can have treatment
in more healthcare-centra.
So the patient should be on the root of an EHR, and the
healthcare-organisation should somewhere appropriate being linked to a
specific treatment/composition, received in that organization.
