4 Information requirements

This clause specifies the information requirements for the Part shape application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.

NOTE 1  A graphical representation of the information requirements is given in Annex C.

NOTE 2  The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.

This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following begins the Part_shape_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Part_shape_arm;
(*

4.1 Required AM ARMs

The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

EXPRESS specification:

*)
USE FROM Part_view_definition_arm;    --  ISO/TS 10303-1023

USE FROM Shape_feature_arm;    --  ISO/TS 10303-1764

USE FROM Shape_property_assignment_arm;    --  ISO/TS 10303-1032
(*

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

Part_view_definition_arm ISO/TS 10303-1023
Shape_feature_arm ISO/TS 10303-1764
Shape_property_assignment_arm ISO/TS 10303-1032

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

4.2 ARM type definitions

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

4.2.1 part_shape_element_definition_select   EXPRESS-G

The part_shape_element_definition_select type is an extensible list of alternate data types that allows for the designation of the data types Shape_feature_definition and Part_shape_element.

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

EXPRESS specification:

*)
TYPE part_shape_element_definition_select = EXTENSIBLE GENERIC_ENTITY SELECT
   (Shape_feature_definition,
    Part_shape_element);
END_TYPE;
(*

4.2.2 part_view_definition_or_part_shape_element_select   EXPRESS-G

The part_view_definition_or_part_shape_element_select type is an extensible list of alternate data types that allows for the designation of the data types Part_shape_element and Part_view_definition.

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

EXPRESS specification:

*)
TYPE part_view_definition_or_part_shape_element_select = EXTENSIBLE SELECT
   (Part_shape_element,
    Part_view_definition);
END_TYPE;
(*

4.2.3 ps_additional_application_domain_enumeration   EXPRESS-G

A ps_additional_application_domain_enumeration provides predefined identifiers for the additional application domains of Additional_view_definition_contexts.

EXPRESS specification:

*)
TYPE ps_additional_application_domain_enumeration = ENUMERATION BASED_ON additional_application_domain_enumeration WITH
   (electrical,
    thermal);
END_TYPE;
(*

Enumerated item definitions:

electrical: the application domain is electrical.

thermal: the application domain is thermal.

4.2.4 ps_initial_application_domain_enumeration   EXPRESS-G

The ps_initial_application_domain_enumeration provides predefined identifiers for the initial application domains of Product_view_definitions.

EXPRESS specification:

*)
TYPE ps_initial_application_domain_enumeration = ENUMERATION BASED_ON initial_application_domain_enumeration WITH
   (electrical,
    thermal);
END_TYPE;
(*

Enumerated item definitions:

electrical: the application domain is electrical.

thermal: the application domain is thermal.

4.3 ARM entity definitions

This subclause specifies the ARM entities for this module. Each ARM application entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entities and definitions are specified below.

4.3.1 General_part_feature   EXPRESS-GMapping table

A General_part_feature is a type of Part_shape_element that represents an external shape feature of a Part_view_definition.

EXPRESS specification:

*)
ENTITY General_part_feature
  SUBTYPE OF (Part_shape_element);
DERIVE
  SELF\Shape_element.product_definitional : BOOLEAN := TRUE;
END_ENTITY;
(*

Attribute definitions:

product_definitional: the General_part_feature shall be definitional.

4.3.2 Part_shape_element   EXPRESS-GMapping table

A Part_shape_element is a type of Shape_element that represents an element of the shape of a Part_view_definition or another Part_shape_element.

EXPRESS specification:

*)
ENTITY Part_shape_element
  SUBTYPE OF (Shape_element);
  SELF\Shape_element.associated_definition : part_view_definition_or_part_shape_element_select;
  definition : OPTIONAL part_shape_element_definition_select;
END_ENTITY;
(*

Attribute definitions:

associated_definition: an inherited attribute whose value shall be of type Part_view_definition.

definition: specifies a Shape_feature_definition or another Part_shape_element that is the definition of this Part_shape_element. The value of this attribute need not be specified.

4.3.3 Part_shape_element_relationship   EXPRESS-GMapping table

A Part_shape_element_relationship is a type of Shape_element_relationship that represents is a relationship between two instances of Part_shape_element.

EXPRESS specification:

*)
ENTITY Part_shape_element_relationship
  SUBTYPE OF (Shape_element_relationship);
  SELF\Shape_element_relationship.related : Part_shape_element;
