   have at least one proximal primitive supertype concept. In many cases this is a top level hierarchy concept. However, in some case one or more intermediate primitive supertypes may exist between the top level concept and a defined concept.
• A concept's proximal primitive supertypes represent aspects of the meaning of that concept that are not formally defined by other

• The chapter on Proximal primitive modeling in the DOCEG explains the role of proximal primitive supertypes in modeling concepts.

Example

In  the concepts C, D, E and F have a single proximal primitive supertype B. While concept A is also primitive, it is a supertype of B so it is not a proximal primitive supertype of these concepts.. Similarly concepts H, J and N have a single proximal primitive supertype G. Concepts L and M have a single proximal primitive supertype I (G is not a proximal primitive for these concepts because it is a supertype of concept I). However, concept Concept P has two proximal primitive concepts supertypes K and I as neither of these is a supertype of the other.
