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.

5.2.1 MIM type definitions

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

5.2.1.1 product_definition_or_breakdown_element_usage   

The product_definition_or_breakdown_element_usage type is an extensible list of alternate data types that allows for the designation of the data types product_definition_usage, and product_definition.

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

EXPRESS specification:

*)
TYPE product_definition_or_breakdown_element_usage = EXTENSIBLE GENERIC_ENTITY SELECT
   (product_definition_usage,
    product_definition);
END_TYPE;
(*

5.2.1.2 product_definition_or_product_definition_relationship   

The product_definition_or_product_definition_relationship type is an extensible list of alternate data types that allows for the designation of the data types product_definition, and product_definition_usage.

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

EXPRESS specification:

*)
TYPE product_definition_or_product_definition_relationship = EXTENSIBLE GENERIC_ENTITY SELECT
   (product_definition,
    product_definition_usage);
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 breakdown_context   

EXPRESS specification:

*)
ENTITY breakdown_context
  SUBTYPE OF (product_definition_relationship);
END_ENTITY;
(*

5.2.2.2 breakdown_element_group_assignment   

EXPRESS specification:

*)
ENTITY breakdown_element_group_assignment
  SUBTYPE OF (group_assignment);
  SELF\group_assignment.assigned_group : product_definition_element_relationship;
  items : SET[1:1] OF product_definition_or_breakdown_element_usage;
END_ENTITY;
(*

Attribute definitions:

assigned_group: the relationship between the breakdown_element_group_assignment and the product_definition_element_relationship which is establishing the relationship that the breakdown_element_usage or product_definition is taking part.

items: the breakdown_element_usage or product_definition which is being related by the product_definition_element_relationship.

5.2.2.3 breakdown_element_realization   

EXPRESS specification:

*)
ENTITY breakdown_element_realization
  SUBTYPE OF (characterized_object, product_definition_element_relationship);
END_ENTITY;
(*

5.2.2.4 breakdown_element_usage   

EXPRESS specification:

*)
ENTITY breakdown_element_usage
  SUBTYPE OF (product_definition_relationship);
END_ENTITY;
(*

5.2.2.5 breakdown_of   

EXPRESS specification:

*)
ENTITY breakdown_of
  SUBTYPE OF (product_definition_relationship);
END_ENTITY;
(*

5.2.2.6 product_definition_element_relationship   

EXPRESS specification:

*)
ENTITY product_definition_element_relationship
  SUBTYPE OF (group);
END_ENTITY;
(*

5.2.2.7 product_definition_group_assignment   

EXPRESS specification:

*)
ENTITY product_definition_group_assignment
  SUBTYPE OF (group_assignment);
  SELF\group_assignment.assigned_group : product_definition_element_relationship;
  items : SET[1:1] OF product_definition_or_product_definition_relationship;
END_ENTITY;
(*

Attribute definitions:

assigned_group: the relationship between product_definition_group_assignment and the product_definition_element_relationship which is establishing the relationship that the product_definition or product_definition_relationship is taking part.

items: the product_definition or product_definition_relationship which is being related by the product_definition_element_relationship.
