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 Class_mim;    --  ISO/TS 10303-1070



USE FROM management_resources_schema    --  ISO 10303-41
  (classification_assignment);



REFERENCE FROM management_resources_schema    --  ISO 10303-41

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

Class_mim	ISO/TS 10303-1070
management_resources_schema	ISO 10303-41
management_resources_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 classification_item   

The classification_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the classification_item type.

NOTE   This empty extensible select requires extension in a further module to ensure that entities that refer to it have at least one valid instantiation.

EXPRESS specification:

*)
TYPE classification_item = EXTENSIBLE GENERIC_ENTITY SELECT;
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_classification_assignment   

The considered group is specified with the inherited attribute assigned_class.

NOTE 1   The considered group may be a class or a characterized_object.

NOTE 2   Specific application modules address particular kinds of classification.

EXAMPLE    The entity applied_security_classification_assignment will be used in order to represent confidentiality level classification.

The meaning of the association is specified with the inherited attribute role.

Where applicable, the following value of classification role name shall be used:

• 'reference': the items to which the classification assignment applies, are by intent incompletely transferred.

NOTE 3   This value can be used when assembly data are exchanged iteratively between two partners, to avoid to send twice the CAD files that contain the geometric representation of each component.

EXPRESS specification:

*)
ENTITY applied_classification_assignment
  SUBTYPE OF (classification_assignment);
  items : SET[1:?] OF classification_item;
END_ENTITY;
(*

Attribute definitions:

items: the set of one or more instances of types listed in classification_item, that are associated with the classification information.

5.2.2.2 applied_classification_assignment_relationship   

EXPRESS specification:

*)
ENTITY applied_classification_assignment_relationship
  SUBTYPE OF (classification_assignment_relationship);
  SELF\classification_assignment_relationship.related : applied_classification_assignment;
  SELF\classification_assignment_relationship.relating : applied_classification_assignment;
END_ENTITY;
(*

Attribute definitions:

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

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