Application module: Configuration item | ISO/TS 10303-1056:2010-03(E) © ISO |
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.

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.
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.
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.

Attribute definitions:

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.
