5.2 MIM EXPRESS short listing

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.

Short names of entities defined in this schema are described in Annex A. Unambiguous identification of this schema is defined in Annex B.

USE FROM management_resources_schema    --  ISO 10303-41
  (external_identification_assignment,
   external_identification_assignment_relationship);



USE FROM support_resource_schema    --  ISO 10303-41
  (identifier);

NOTE 1   The schemas referenced above are specified in the following part of ISO 10303:

management_resources_schema	ISO 10303-41
support_resource_schema	ISO 10303-41

NOTE 2   See Annex D, Figures D.1and D.2 for a graphical representation of this schema.

5.2.1 MIM type definition

This subclause specifies the MIM type for this application module. The MIM type and definition is specified below.

5.2.1.1 external_identification_item   

The external_identification_item type is an extensible list of alternate data types that allows for the designation of the data type applied_external_identification_assignment.

NOTE   The list of entity data types may be extended in application modules that use the constructs of this module.

EXPRESS specification:

*)
TYPE external_identification_item = EXTENSIBLE GENERIC_ENTITY SELECT
   (applied_external_identification_assignment);
END_TYPE;
(*

5.2.2 MIM entity definitions

This subclause specifies the MIM entities for this module. The MIM entities and definitions are specified below.

5.2.2.1 applied_external_identification_assignment   

EXPRESS specification:

*)
ENTITY applied_external_identification_assignment
  SUBTYPE OF (external_identification_assignment);
  items : SET[1:?] OF external_identification_item;
END_ENTITY;
(*

Attribute definitions:

items: the set of external_identification_item to which external identification is assigned.

5.2.2.2 applied_external_identification_assignment_relationship   

EXPRESS specification:

*)
ENTITY applied_external_identification_assignment_relationship
  SUBTYPE OF (external_identification_assignment_relationship);
  SELF\external_identification_assignment_relationship.related : applied_external_identification_assignment;
  SELF\external_identification_assignment_relationship.relating : applied_external_identification_assignment;
END_ENTITY;
(*

Attribute definitions:

related: the other object of applied_external_identification_assignment that is part of the relationship.

relating: one object of applied_external_identification_assignment that is part of the relationship.
