• All concepts except the

   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  Concept A is also primitive, but 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 (. Note that G is not a proximal primitive supertype for these concepts because it is a supertype of concept I). Concept In this hierarchy only concept P has two more than one proximal primitive supertypes. The proximal primitive supertypes of concept P are concepts K and I as neither of these concepts is a supertype of the other.
