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 type
for this application module. The MIM type and
definition is specified below.
The eri_external_identification type is an extension
of the
external_identification_item type.
It adds the data
type
externally_defined_representation_item
to the list of alternate data types.

This subclause specifies the MIM entities for this
module. The MIM entities and definitions are specified below.
An externally_defined_representation is a type of
externally_defined_item
and
representation
that implements the ARM concept of
External_representation_item.
An externally_defined_representation value is defined in an external library.
