Gerard Several points: 1.Specifically, openEHR proposes a number of Reference Models, supplemented by Archetype Models.
2. You seem to use the word 'Kernel' as a synonym for Reference Model. If this is not so, please will you explain your use of the word Kernel? 3. The Reference Models proposed by openEHR are just sufficient to meet the set of published requirements (e.g. ISO 18308) for an EHR and apply to _any_ EHR. It is necessary to delineate various levels in the Architecture in order to be able to place Classes, Attributes, and Functions appropriately to meet the requirements. 4. The Reference Models are indeed generic, in the usual sense that they are not prescriptive about what _information_ must be in an EHR, but make possible the representation of all those kinds of information known to exist in (or be necessary for future) EHRs. 5. For each Reference Model there will be a corresponding Archetype Model (only the Data Types Archetype model has so far been released). Authors of actual Archetypes, conforming to the Archetype models, will be able to impose the required constraints of their domains to guide the construction of instances of EHRs. 6. To my way of thinking, everything about the Reference Models is _generic_. Archetypes provide the means of using the models to construct EHRs for particular, i.e. non-generic, domains. I hope this helps to resolve what appears to be a fundamental difference between us!
