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 component_material_relationship_assignment_item   

The component_material_relationship_assignment_item type is an extensible list of alternate data types that allows for the designation of the data types assembly_item_number, assembly_component_usage, and specification_definition.

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

EXPRESS specification:

*)
TYPE component_material_relationship_assignment_item = EXTENSIBLE SELECT
   (assembly_item_number,
    assembly_component_usage,
    specification_definition);
END_TYPE;
(*

5.2.1.2 pudv_groupable_item   

The pudv_groupable_item type is an extension of the groupable_item type. It adds the data types assembly_component, and assembly_component_usage to the list of alternate data types.

EXPRESS specification:

*)
TYPE pudv_groupable_item = SELECT BASED_ON groupable_item WITH
   (assembly_component,
    assembly_component_usage);
END_TYPE;
(*

5.2.1.3 pudv_requirement_assigned_item   

The pudv_requirement_assigned_item type is an extension of the requirement_assigned_item type. It adds the data types assembly_component_usage, assembly_item_number, and component_material_relationship to the list of alternate data types.

EXPRESS specification:

*)
TYPE pudv_requirement_assigned_item = SELECT BASED_ON requirement_assigned_item WITH
   (assembly_component_usage,
    assembly_item_number,
    component_material_relationship);
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 assembly_item_number   

EXPRESS specification:

  SUBTYPE OF (group, applied_group_assignment);
  SELF\applied_group_assignment.items : SET[1:?] OF assembly_component_usage;
DERIVE
  SELF\group_assignment.assigned_group : group := SELF;
END_ENTITY;
(*

Attribute definitions:

items: an inherited attribute shall be of type assembly_component_usage for the assembly_item_number.

assigned_group: an inherited attribute shall be of type group for the assembly_item_number.

5.2.2.2 component_material_relationship   

EXPRESS specification:

*)
ENTITY component_material_relationship
  SUBTYPE OF (group, property_definition);
  SELF\property_definition.definition : physical_unit;
END_ENTITY;
(*

Attribute definitions:

definition: an inherited attribute shall be of type physical_unit for the component_material_relationship.

5.2.2.3 component_material_relationship_assignment   

EXPRESS specification:

*)
ENTITY component_material_relationship_assignment
  SUBTYPE OF (group_assignment, role_association);
  SELF\group_assignment.assigned_group : component_material_relationship;
  items : SET[1:1] OF component_material_relationship_assignment_item;
DERIVE
  SELF\role_association.item_with_role : component_material_relationship_assignment := SELF;
END_ENTITY;
(*

Attribute definitions:

assigned_group: an inherited attribute shall be of type component_material_relationship for the component_material_relationship_assignment.

items: specifies a role of the component_material_relationship_assignment_item for the component_material_relationship_assignment. There shall exist exactly one component_material_relationship_assignment_item for the component_material_relationship_assignment.

item_with_role: an inherited attribute shall be of type component_material_relationship_assignment for the component_material_relationship_assignment.

5.2.2.4 next_assembly_usage_occurrence_relationship   

EXPRESS specification:

*)
ENTITY next_assembly_usage_occurrence_relationship
  SUBTYPE OF (next_assembly_usage_occurrence, product_definition_occurrence_relationship);
DERIVE
  SELF\product_definition_occurrence_relationship.occurrence_usage : next_assembly_usage_occurrence_relationship := SELF;
