4 Information requirements

This clause specifies the information requirements for the Component feature 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 Component_feature_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Component_feature_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 Assembly_component_arm;    --  ISO/TS 10303-1802

USE FROM Assembly_shape_arm;    --  ISO/TS 10303-1808
(*

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

Assembly_component_arm ISO/TS 10303-1802
Assembly_shape_arm ISO/TS 10303-1808

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

4.2 ARM type definition

This subclause specifies the ARM type for this application module. The ARM type and definition is specified below.

4.2.1 cf_groupable_item   EXPRESS-G

The cf_groupable_item type is an extension of the groupable_item type. It adds the data type Component_feature to the list of alternate data types.

EXPRESS specification:

*)
TYPE cf_groupable_item = SELECT BASED_ON groupable_item WITH
   (Component_feature);
END_TYPE;
(*

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 Component_feature   EXPRESS-GMapping table

A Component_feature is a type of Shape_element The location of the Component_feature in the assembly model is derived from the placement of the associated_definition in the assembly model and the placement of the definition model in the derived_from model of that associated_definition.

EXPRESS specification:

*)
ENTITY Component_feature
  SUBTYPE OF (Shape_element);
  definition : OPTIONAL Part_shape_element;
  SELF\Shape_element.associated_definition : Assembly_component;
DERIVE
  SELF\Shape_element.product_definitional : BOOLEAN := TRUE;
UNIQUE
  UR1: definition, associated_definition;
  UR2: SELF\Shape_element.element_name, associated_definition;
END_ENTITY;
(*

Attribute definitions:

definition: the General_part_feature that serves as a definition for the Component_feature. The value of this attribute need not be specified.

associated_definition: the Assembly_component that has the Component_feature.

NOTE    The subtypes of Component_feature specify specializations of Assembly_component that are consistent with the subtype of definition.

product_definitional: a Component_feature is always definitional.

Formal propositions:

UR1: The combination of definition and associated_definition shall be unique within a population of Component_feature.

UR2: The combination of element_name and associated_definition shall be unique within a population of Component_feature.

4.3.2 Component_feature_joint   EXPRESS-GMapping table

A Component_feature_joint is a type of Component_feature_relationship and of Shape_element for the representation of a joint between two Component_features.

EXPRESS specification:

*)
ENTITY Component_feature_joint
  ABSTRACT SUPERTYPE
  SUBTYPE OF (Component_feature_relationship, Shape_element);
  SELF\Component_feature_relationship.relating RENAMED feature_1 : Component_feature;
  SELF\Component_feature_relationship.related RENAMED feature_2 : Component_feature;
  SELF\Shape_element.associated_definition : Assembly_definition;
WHERE
  WR1: feature_1 <> feature_2;
  WR2: associated_definition IN feature_1\Shape_element.associated_definition\Assembly_component.assemblies;
  WR3: associated_definition IN feature_2\Shape_element.associated_definition\Assembly_component.assemblies;
END_ENTITY;
(*

Attribute definitions:

feature_1: specifies one role of the Component_feature for the Component_feature_joint.

feature_2: specifies another role of the Component_feature for the Component_feature_joint.

associated_definition: specifies the Assembly_definition to which the Component_feature_joint belongs.

Formal propositions:

WR1: the feature_1 and feature_2 shall not point to the same instance of Component_feature.

WR2: the Component_feature referenced by feature_1 shall be used by the same Assembly_definition as the associated_definition.

WR3: the Component_feature referenced by feature_2 shall be used by the same Assembly_definition as the associated_definition.

4.3.3 Component_feature_make_from_relationship   EXPRESS-GMapping table

A Component_feature_make_from_relationship is a type of Component_feature_relationship. A Component_feature_make_from_relationship is an association between two Component_feature, where one Component_feature is used as a basis for the development of another Component_feature.

EXPRESS specification:

*)
ENTITY Component_feature_make_from_relationship
  SUBTYPE OF (Component_feature_relationship);
  SELF\Shape_element_relationship.relating RENAMED reusable_feature : Component_feature;
  SELF\Shape_element_relationship.related RENAMED resultant_feature : Component_feature;
END_ENTITY;
(*

Attribute definitions:

reusable_feature: specifies the Component_feature that is modified or reused to become the resultant_feature in the Component_feature_make_from_relationship.

resultant_feature: specifies the Component_feature that results from modifying or reusing the reusable_feature in the Component_feature_make_from_relationship.

4.3.4 Component_feature_relationship   EXPRESS-GMapping table

A Component_feature_relationship is a type of Shape_element_relationship. A Component_feature_relationship is the association between two Component_feature. A Component_feature_relationship may be a Component_feature_joint or a Component_feature_make_from_relationship.

EXPRESS specification:

*)
ENTITY Component_feature_relationship
  SUPERTYPE OF (ONEOF (Component_feature_joint,
                       Component_feature_make_from_relationship))
  SUBTYPE OF (Shape_element_relationship);
  SELF\Shape_element_relationship.relating : Component_feature;
  SELF\Shape_element_relationship.related : Component_feature;
END_ENTITY;
(*

Attribute definitions:

relating: the first instance of Component_feature that is part of the relationship.

related: the second of the instances of Component_feature that is part of the relationship. If one element of the relationship is dependent upon the other, this attribute shall be the dependent one.

4.3.5 Component_terminal   EXPRESS-GMapping table

A Component_terminal is a type of Component_feature. A Component_terminal is the defined conductive shape for conductors from other components to access the electrical functionality of the Assembly_component.

EXPRESS specification:

*)
ENTITY Component_terminal
  ABSTRACT SUPERTYPE
  SUBTYPE OF (Component_feature);
  local_swappable : OPTIONAL BOOLEAN;
  global_swappable : OPTIONAL BOOLEAN;
  swap_code : OPTIONAL STRING;
END_ENTITY;
(*

Attribute definitions:

local_swappable: specifies a Boolean value that indicates if the terminal can be exchanged within the associated functional unit. The value of this attribute need not be specified.

global_swappable: specifies a Boolean value that indicates if the terminal can be exchanged within associated functional units of the same type. The value of this attribute need not be specified.

swap_code: specifies a string for the Component_terminal. The value of this attribute need not be specified.
