4 Information requirements

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;
(*

4.1 Required AM ARM

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

EXPRESS specification:

*)
USE FROM Class_arm;    --  ISO/TS 10303-1070
(*

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

Class_arm ISO/TS 10303-1070

NOTE 2   See Annex C, Figures C.1and C.2 for a graphical representation of this schema.

4.2 ARM type definition

This subclause specifies the ARM type for this application module. The ARM type and definition is specified below.

4.2.1 classification_item   EXPRESS-G

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;
(*

4.3 ARM entity definitions

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.

4.3.1 Classification_assignment   EXPRESS-GMapping table

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.

4.3.2 Classification_assignment_relationship   EXPRESS-GMapping table

A Classification_assignment_relationship is a relationship between two Classification_assignment objects.

EXPRESS specification:

*)
ENTITY Classification_assignment_relationship;
  description : OPTIONAL STRING;
  id : OPTIONAL STRING;
  related : Classification_assignment;
  relating : Classification_assignment;
  relation_type : STRING;
WHERE
  WR1: relating :<>: related;
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.
