Bert, I fully get your point... but I would argue that, as it goes in maths and physics, choosing a Cartesian or Polar reference frame plainly depends on the kind of issue to be addressed. As you very well said, role-based access is always Cartesian since it defines the roles "inside the organization"... usually as a matrix. It is actually the easy way inside an hospital or any care place. But it becomes messy when multiple unrelated domains are artificially grouped in a large virtual box, as it is done in regional or national wide systems... since the role of a given practitioner inside the virtual box cannot be clearly defined. As an example, as a radiologist, is she allowed to access any image form any care place? My opinion is that the polar reference frame seamlessly "scales in complexity": it is more complicated to operate inside a "hierarchical ordered box" (as is a single organization), but becomes natural in a network of actors when considered from one of its nodes (ie the patient). Best, Philippe
