This clause specifies the EXPRESS schema derived from the mapping
table.
It uses elements from the common resources or from other application
modules and defines the EXPRESS constructs that are specific to this
part of ISO 10303.
This clause constitutes the Module Interpreted Module (MIM) of the
application module.
This clause also
specifies the modifications that apply to the constructs
imported from the common resources.
The following restrictions apply to the use, in this schema, of constructs defined in common resources or in application
modules:
-
use of a supertype entity does not make applicable any of its
specializations, unless the specialization is also imported in the
MIM schema;
-
use of a SELECT type does not make applicable any of its listed types
unless the listed type is also imported in the MIM schema.

This subclause specifies the MIM entity for this
module. The MIM entity and definition is specified below.
A geometric_model_element_relationship is a type of
geometric_representation_item
and a type of
representation_item_relationship
that implements the ARM concept of
Geometric_model_element_relationship.

Attribute definitions:
relating_representation_item:
an attribute inherited from the

shall be redeclared as the

for the geometric_model_element_relationship.
related_representation_item:
an attribute inherited from the
representation_item_relationship
shall be redeclared as the
geometric_representation_item
for the geometric_model_element_relationship.
Formal propositions:
UR1:
The combination of relating_representation_item and related_representation_item
shall be unique within a population of geometric_model_element_relationship.
WR1:
The relating_representation_item shall not be related_representation_item.
