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.

The following EXPRESS specification 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 Identification_assignment_arm;    --  ISO/TS 10303-1021

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:

Identification_assignment_arm ISO/TS 10303-1021
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 type definition

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

4.2.1 requirement_view_definition_identification_item   EXPRESS-G

The requirement_view_definition_identification_item type is an extension of the identification_item type. It adds the data type Requirement_view_definition to the list of alternate data types.

EXPRESS specification:

*)
TYPE requirement_view_definition_identification_item = SELECT BASED_ON identification_item WITH
   (Requirement_view_definition);
END_TYPE;
(*

4.3 ARM entity definition

This subclause specifies the ARM entity for this module. The ARM entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entity and definition is specified below.

4.3.1 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.
