Application module: Product group | ISO/TS 10303-1278:2004(E) © ISO |
This clause specifies the information requirements for the Product group 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 Product_group_arm schema and identifies the necessary external references.

NOTE 2 See Annex C, Figures C.1and C.2 for a graphical representation of this schema.
This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.
The product_group_classification_item type is an extension of the classification_item type. It adds the data types Product_group and Product_group_relationship to the list of alternate data types.
Using Classification_assignment, a Class can be assigned to the entities in product_group_classification_item.EXPRESS specification:
*)
TYPE
product_group_classification_item =
SELECT
BASED_ON
classification_item
WITH
(Product_group,
Product_group_relationship);
END_TYPE;
(*
The product_group_effectivity_item type is an extension of the effectivity_item type. It adds the data types Product_group, Product_group_membership and Product_group_relationship to the list of alternate data types.
Using Effectivity_assignment, an Effectivity can be assigned to the entities in product_group_effectivity_item.EXPRESS specification:
*)
TYPE
product_group_effectivity_item =
SELECT
BASED_ON
effectivity_item
WITH
(Product_group,
Product_group_membership,
Product_group_relationship);
END_TYPE;
(*
The product_group_property_assignment_select type is an extension of the property_assignment_select type. It adds the data type Product_group_membership to the list of alternate data types.
NOTE The list of entity data types may be extended in application modules that use the constructs of this module.
EXPRESS specification:
*)
TYPE
product_group_property_assignment_select =
EXTENSIBLE
SELECT
BASED_ON
property_assignment_select
WITH
(Product_group_membership);
END_TYPE;
(*
The product_select type is an extensible list of alternate data types that allows for the designation of the data types Product, Product_as_individual, Product_concept, Product_group and Product_version.
NOTE The list of entity data types may be extended in application modules that use the constructs of this module.
Using Product_group_membership, the entities in the product_select type, Product_concepts, Products, Product_versions, Product_as_individuals or Product_groups can be identified as a member of a product group.EXPRESS specification:
*)
TYPE
product_select =
EXTENSIBLE
SELECT
(Product,
Product_as_individual,
Product_concept,
Product_group,
Product_version);
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.
EXAMPLE All the aircraft sold to BigPlanes airways.
EXPRESS specification:

ENTITY Product_group;
id : STRING;
description :
OPTIONAL

purpose : STRING;
membership_rule :
OPTIONAL

END_ENTITY;
(*
Attribute definitions:
id: the identifier that distinguishes the product group.
description: the text that provides further information about the characteristics which defines this group. The value of this attribute need not be specified.
purpose: the text that provides further information about the objectives of this product group.
EXAMPLE 1 All individual products which are subject of a planned maintenance.
membership_rule: the characteristics that are common to all members of this group. The value of this attribute need not be specified.
product_group_context: the context in which the product group has meaning. The value of this attribute need not be specified.
EXAMPLE 2 The project or equipment end item to which the group belongs.
EXPRESS specification:
*)
ENTITY Product_group_membership;
member : product_select;
of_group : Product_group;
END_ENTITY;
(*
Attribute definitions:
member: the instance that is a member of the Product_group.
of_group: the Product_group to which the instance identified by member belongs.
NOTE A subset is a common type of relationship. It indicates that one Product_group is a subset of another.
EXPRESS specification:
*)
ENTITY Product_group_relationship;
description :
OPTIONAL
STRING;
relating : Product_group;
related : Product_group;
role :
OPTIONAL
STRING;
END_ENTITY;
(*
Attribute definitions:
description: the text that provides further information about the Product_group_relationship. The value of this attribute need not be specified.
relating: one of the instances of Product_group that is a part of the relationship.
related: the other instance of Product_group that is part of the relationship. If one element of the relationship is dependent upon the other, this attribute shall be the dependent one.
role: the possible functions of a Product_group_relationship in particular contexts. The value of the attribute need not be specified.
