I'm reviewing the specs & the openEHR terminology.
I understand the "event" and "persistent" values for the Composition.category property.
There is also a "process" value, but I don't understand the difference between "event" and "process". The specs are not clear here:
"Indicates what broad category this Composition is belogs to, e.g. "persistent" - of longitudinal validity, "event", "process" etc."
The only current allowed values are event and persistent. I am not quite sure what process might mean in this context. This was clearly some philosophical musing when the spec was written but I have not come across a need for this when modelling so far. I have requested a change to allow a persistent composition to have a context attribute , currently disallowed. Episodic care such as hospital admission does throw up the need for persistent compositions to carry the context of the episode but persist throughout that episode. eg a problem list for the current admission.
I think having "process" & "etc" in the specs makes a little difficult to understand what values are allowed in the category field.
BTW, in the Terminology.xml file, "process" is also present: http://www.openehr.org/releases/1.0.2/architecture/computable/terminology/terminology.xml
