This clause specifies the information requirements for the
Product categorization
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
Product_categorization_arm
schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Product_categorization_arm;

The following EXPRESS interface statement specifies the elements
imported from the ARM of another application module.

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

ISO/TS 10303-1017 |
NOTE 2
See Annex C,
Figures
C.1and C.2
for a graphical representation of this schema.
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.
A Product_category is a type of product that is defined for a purpose that is specific to a module or application protocol.
NOTE
For the purpose of a general classification of
products, use entity Class
and Classification_assignment, standardized in ISO/TS 10303-1070 and ISO/TS 10303-1114.
EXPRESS specification:
*)
ENTITY Product_category;
id :
OPTIONAL
STRING;
name : STRING;
description :
OPTIONAL
STRING;
END_ENTITY;
(*
Attribute definitions:
id:
the identifier that distinguishes the Product_category.
The value of this attribute need not be specified.
name:
the words by which the Product_category is known.
EXAMPLE
"part" and "document" are examples of categories of product.
description:
the text that provides further information about the Product_category.
The value of this attribute need not be specified.
A Product_category_assignment is the inclusion of one or more products in a product category.
NOTE
Usually, products are classified in categories of products. However, at some early phase of design, a product may not yet
be categorized.
EXAMPLE
A product may belong to categories named 'part', 'raw material', 'document', 'functionality', or 'requirement'.
EXPRESS specification:
*)
ENTITY Product_category_assignment;
category : Product_category;
products : SET[1:?] OF Product;
END_ENTITY;
(*
Attribute definitions:
category:
the Product_category
that contains the products.
products:
the instances of Product
which identify members of the product category.
A Product_category_hierarchy is a hierarchical relationship between one instance of Product_category
and another.
EXPRESS specification:
*)
ENTITY Product_category_hierarchy;
super_category : Product_category;
sub_category : Product_category;
END_ENTITY;
(*
Attribute definitions:
super_category:
one instance of Product_category
that participates in the relationship.
sub_category:
the instance of Product_category
that is dependent upon the other.
This subclause specifies the ARM function for
this module. The ARM function and definition is
specified below.
The types_of_product function returns the set of product category names associated with the argument.
The function evaluates the bag of instances of Product_category
that are associated with the input Product
through an instance of Product_category_assignment.
The function returns the SET of STRING values stored in the name
attribute of the instances of Product_category
in the bag.
EXPRESS specification:
*)
FUNCTION types_of_product (obj : Product) :SET OF STRING;
LOCAL
category_assignments : BAG OF Product_category_assignment;
categories : SET OF STRING := [];
i : INTEGER;
END_LOCAL;
category_assignments := USEDIN(obj, 'PRODUCT_CATEGORIZATION_ARM.' + 'PRODUCT_CATEGORY_ASSIGNMENT.PRODUCTS');
REPEAT i := LOINDEX(category_assignments) TO HIINDEX(category_assignments) BY 1;
categories := categories + category_assignments[i].category.name;
END_REPEAT;
RETURN (categories);
END_FUNCTION;
(*
Argument definitions:
obj:
the Product
whose categories are considered.
