A terminology is not a data model. And OIO does (I think) have a data
model, in fact many, user-definable data models, which results in an
underlying physical data model like this (using an E-R style diagram,
where --> means has zero or more):

Patient
   -->FormA
   -->FormB
   -->FormC
   -->etc

Or if you prefer a more O-O view:

PatientInstances
  -->FormInstances
     -->Value-AttributeInstances

The latter view doesn't show that there are various Value-Attribute
subclasses available, but UML diagrams in ASCII are a bit challenging to
compose. Of course, I have only superficial knowledge of OIO, so I might
be completely wrong.
