This clause specifies the information requirements for the
Configuration item
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.
The following EXPRESS specification begins the
Configuration_item_arm
schema and identifies the necessary external references.
EXPRESS specification:

This subclause specifies the ARM type
for this application module. The ARM type and
definition is specified below.
The version_or_definition type is a formal mechanism to refer either to a Product_version or to a Product_view_definition.
EXPRESS specification:
*)
TYPE
version_or_definition =
SELECT
(Product_version,
Product_view_definition);
END_TYPE;
(*
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.
An Item_design_association is the association of a Product_configuration with a
Product_view_definition or a Product_version.
It specifies the design that corresponds to the Product_configuration.
If the design is a Product_view_definition, the Item_design_association represents the statement that, in the considered definition context, the product version, that is, the Product_view_definition is a valid way to implement the Product_configuration.
NOTE 1
This association might not be valid in all definition contexts of the product version.
If the design is a Product_version, the Item_design_association represents the statement that, in all definition contexts, the Product_version is a valid way to implement the Product_configuration.
NOTE 2
The association might not be valid for other versions of the product.
EXPRESS specification:
*)
ENTITY Item_design_association;
configuration : Product_configuration;
design : version_or_definition;
UNIQUE
UR1: configuration, design;
END_ENTITY;
(*
Attribute definitions:
configuration:
the Product_configuration for which a product solution is designated.
design:
the Product_version or the Product_view_definition that identifies a product which is a valid implementation for the Product_configuration.
Formal propositions:
UR1:
There shall be at most one instance of with the same combination of
configuration and design.
NOTE
However, a product version may be a valid implementation for several configuration items.
A Product_configuration is the identification of a Product_concept as a configuration.
NOTE 1
The entity Product_configuration corresponds to the concept of configuration item defined, in some configuration management standards, as an item subject
to configuration management.
EXAMPLE
A Product_configuration may represent a component of a contracted product, onto which severe safety rules apply and for which configuration management
is therefore rigorously applied.
NOTE 2
A Product_configuration may identify a variation of a Product_concept, an entire Product_concept, or some
portion thereof.
NOTE 3
A Product_configuration can be established prior to the existence of a corresponding product.
EXPRESS specification:
*)
ENTITY Product_configuration;
id : STRING;
name : STRING;
description :
OPTIONAL
STRING;
item_context : Product_concept;
INVERSE
corresponding_design : SET[0:1] OF Item_design_association FOR configuration;
END_ENTITY;
(*
Attribute definitions:
id:
the identification of the identifier that distinguishes the configuration item.
name:
the words by which the configuration item is known.
description:
the
text that provides further information about the Product_configuration. The value of the attribute need not be specified.
item_context:
the Product_concept that defines the context in which the configuration item has been defined.
corresponding_design:
the set of instances of the entity data type Item_design_association that identify products which provide a solution for the configuration item.
In this version of the application module, the cardinality of the set shall be not higher than one.
A Product_configuration_hierarchical_relationship is a type of
Product_configuration_relationship
that is used to represent a hierarchical relationship between a parent
Product_configuration
and a child
Product_configuration.
EXPRESS specification:
*)
ENTITY Product_configuration_hierarchical_relationship
SUBTYPE OF (Product_configuration_relationship);
SELF\Product_configuration_relationship.related_product_configuration RENAMED child : Product_configuration;
SELF\Product_configuration_relationship.relating_product_configuration RENAMED parent : Product_configuration;
END_ENTITY;
(*
Attribute definitions:
child:
the child
Product_configuration
of the relationship.
parent:
the parent
Product_configuration
of the relationship.
A Product_configuration_relationship is a relationship between a pair of
Product_configurations.
EXPRESS specification:
*)
ENTITY Product_configuration_relationship
SUPERTYPE OF (ONEOF (Product_configuration_hierarchical_relationship,
Product_configuration_revision_sequence));
relating_product_configuration : Product_configuration;
related_product_configuration : Product_configuration;
END_ENTITY;
(*
Attribute definitions:
relating_product_configuration:
one of the instances of
Product_configuration
that is a part of the relationship.
related_product_configuration:
the other instance of
Product_configuration
that is a part of the relationship.
If one element of the relationship is dependent upon the other, this
attribute shall be the dependent one.
A Product_configuration_revision_sequence is a type of
Product_configuration_relationship
that is used to relate a previous version (predecessor) of a
Product_configuration
to the version that replaces it (successor).
EXPRESS specification:
*)
ENTITY Product_configuration_revision_sequence
SUBTYPE OF (Product_configuration_relationship);
SELF\Product_configuration_relationship.relating_product_configuration RENAMED predecessor : Product_configuration;
SELF\Product_configuration_relationship.related_product_configuration RENAMED successor : Product_configuration;
END_ENTITY;
(*
Attribute definitions:
predecessor:
the preceding Product_configuration in the relationship.
successor:
the succeeding Product_configuration in the relationship.
