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 document_identifier_assigned_item   

The document_identifier_assigned_item type allows for the designation of the data type document.

EXPRESS specification:

*)
TYPE document_identifier_assigned_item = SELECT
   (document);
END_TYPE;
(*

5.2.1.2 sd_document_reference_item   

The sd_document_reference_item type is an extension of the document_reference_item type. It adds the data types configuration_item, product, product_definition, and product_definition_formation to the list of alternate data types.

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

EXPRESS specification:

*)
TYPE sd_document_reference_item = EXTENSIBLE GENERIC_ENTITY SELECT BASED_ON document_reference_item WITH
   (configuration_item,
    product,
    product_definition,
    product_definition_formation);
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 document_identifier   

EXPRESS specification:

*)
ENTITY document_identifier
  SUBTYPE OF (group);
UNIQUE
  UR1: SELF\group.name, SELF\group.description;
END_ENTITY;
(*

Formal propositions:

UR1: The combination of name and description shall be unique within a population of document_identifiers.

5.2.2.2 document_identifier_assignment   

A document_identifier_assignment is a type of group_assignment that specifies one or more of document_identifier_assigned_item. If there are more than one, then the items are all revisions of the same drawing.

EXAMPLE    A schematic diagram may have a base identifier and each revision identification of that diagram differs from other revisions identification only in the document.description.

NOTE    Due to a constraint on document_identifier, no member of document_identifier may be referenced more than once, guaranteeing uniqueness of assigned_group.

EXPRESS specification:

*)
ENTITY document_identifier_assignment
  SUBTYPE OF (group_assignment);
  SELF\group_assignment.assigned_group : document_identifier;
  items : SET[1:?] OF document_identifier_assigned_item;
END_ENTITY;
(*

Attribute definitions:

assigned_group: an attribute inherited from the group_assignment shall be redeclared as the document_identifier for the document_identifier_assignment.

items: specifies a role of the document_identifier_assigned_item for the document_identifier_assignment.

5.2.2.3 partial_document_with_structured_text_representation_assignment   

EXPRESS specification:

*)
ENTITY partial_document_with_structured_text_representation_assignment
  SUBTYPE OF (applied_document_usage_constraint_assignment, characterized_object);
END_ENTITY;
(*

5.2.2.4 specification_definition   

An specification_definition is a type of product_definition which implements the ARM concepts of:

• Design_specification;
• Specification_definition;
• Fabrication_technology_specification;
• Interface_specification_document_definition;
• Language_reference_manual;
• Material_specification;
• Process_specification;
• Surface_finish_specification;
• Test_specification.

EXPRESS specification:

*)
ENTITY specification_definition
  SUBTYPE OF (product_definition);
END_ENTITY;
