This clause specifies the information requirements for the
Classification assignment
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
Classification_assignment_arm
schema and identifies the necessary external references.
EXPRESS specification:

SCHEMA Classification_assignment_arm;

for a graphical representation of this schema.
This subclause specifies the ARM type
for this application module. The ARM type and
definition is specified below.
The classification_item type is an
extensible list of alternate data types
that allows for the designation of the data
type .
NOTE
The list of entity data types may be
extended in application modules that use the constructs of
this module.
EXPRESS specification:
*)
TYPE
classification_item =
EXTENSIBLE
GENERIC_ENTITY
SELECT;
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.
A Classification_assignment is the assignment of a Class to product or activity data for their classification. That means that every member of items belongs to the assigned_class.
EXPRESS specification:
*)
ENTITY Classification_assignment;
assigned_class : Class;
items : SET[1:?] OF classification_item;
role :
OPTIONAL
STRING;
END_ENTITY;
(*
Attribute definitions:
assigned_class:
the Class that is considered in the assignment.
items:
the set or more instances of types listed in classification_item that are classified.
role:
the meaning of the relationship between the assigned_class and the associated items.
The value of this attribute need not be specified.
NOTE
When there is a specific role, the assignment has extra information that can be useful to differentiate this assignment from
others.When all the items are assigned to the same Class in the same way there is no need to specify a role. Just when it is needed to distinguish them, the role attribute is useful.
EXAMPLE 1
The role for 'electromagnetic compatibility' has the associated object that is a classification that categorizes the classified
element in respect of its ability to comply with requirements concerning electromagnetic interference.
EXAMPLE 2
The role for 'environmental conditions' has the associated object that is a classification that categorizes the classified
element in respect of its ability to comply with environmental impact requirements.
A Classification_assignment_relationship is a relationship between two
Classification_assignment
objects.
EXPRESS specification:
*)
ENTITY Classification_assignment_relationship;

id :

STRING;
related : Classification_assignment;
relating : Classification_assignment;
relation_type : STRING;

END_ENTITY;
(*
Attribute definitions:
description:
the text that provides further information about the Classification_assignment_relationship. The value of this attribute need not be specified.
id:
the identifier for the Classification_assignment_relationship. The value of this attribute need not be specified.
related:
the other object of
Classification_assignment
that is part of the relationship.
relating:
one object of
Classification_assignment
that is part of the relationship.
relation_type:
the meaning of the relationship.
Formal propositions:
WR1:
the related and the relating must be different.
