4 Information requirements

This clause specifies the information requirements for the Requirement view definition 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 Requirement_view_definition_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Requirement_view_definition_arm;
(*

4.1 Required AM ARMs

The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

EXPRESS specification:

*)
USE FROM Property_as_definition_arm;    --  ISO/TS 10303-1399

USE FROM Product_view_definition_arm;    --  ISO/TS 10303-1019

USE FROM Requirement_identification_and_version_arm;    --  ISO/TS 10303-1140
(*

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

Property_as_definition_arm ISO/TS 10303-1399
Product_view_definition_arm ISO/TS 10303-1019
Requirement_identification_and_version_arm ISO/TS 10303-1140

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

4.2 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.

4.2.1 Requirement_view_definition   EXPRESS-GMapping table

A Requirement_view_definition is a type of Product_view_definition that provides a view of a requirement version relevant for one or more application domains. This view collects requirement data for specific engineering purposes.

EXAMPLE    An engineer may have responsibility for collecting all requirements associated with the cooling of an engine - covering engine block, tubing, water pump, electric fan.

Some requirements in a Requirement_view_definition might impact on different disciplines. Multiple Requirement_view_definition objects may be used to present different views of a given requirement for each discipline.

EXPRESS specification:

*)
ENTITY Requirement_view_definition
  SUBTYPE OF (Product_view_definition);
  SELF\Product_view_definition.defined_version : Requirement_version;
END_ENTITY;
(*

Attribute definitions:

defined_version: the Requirement_version that the Requirement_view_definition defines.

4.2.2 Single_requirement_view_definition   EXPRESS-GMapping table

A Single_requirement_view_definition is a type of Requirement_view_definition that is defined by a single property.

EXPRESS specification:

*)
ENTITY Single_requirement_view_definition
  SUBTYPE OF (Requirement_view_definition);
INVERSE
  definition : Single_property_is_definition FOR described_element;
END_ENTITY;
(*

Attribute definitions:

definition: the single_property_is_definition that is the definition for the Single_requirement_view_definition.
