4 Information requirements

This clause specifies the information requirements for the Product view definition relationship 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 Product_view_definition_relationship_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Product_view_definition_relationship_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 Product_view_definition_arm;    --  ISO/TS 10303-1019
(*

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

Product_view_definition_arm ISO/TS 10303-1019

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 View_definition_relationship   EXPRESS-GMapping table

A View_definition_relationship is an association between two instances of Product_view_definition.

This association represents a relationship between the product versions, indirectly identified by the instances of Product_view_definition, relevant in the definition contexts of the related instances of Product_view_definition.

EXPRESS specification:

*)
ENTITY View_definition_relationship;
  id : OPTIONAL STRING;
  relation_type : OPTIONAL STRING;
  description : OPTIONAL STRING;
  relating_view : Product_view_definition;
  related_view : Product_view_definition;
END_ENTITY;
(*

Attribute definitions:

id: the identifier for the View_definition_relationship. The value of this attribute need not be specified.

relation_type: the meaning of the relationship. The value of this attribute need not be specified. In particular, this attribute is not required in subtypes of this entity.

description: the text that provides further information about the View_definition_relationship. The value of this attribute need not be specified.

relating_view: one of the instances of Product_view_definition that is a part of the relationship.

related_view: the other instance of Product_view_definition that is part of the relationship. If one element of the relationship is dependent upon the other, this attribute shall be the dependent one.

4.2.2 View_definition_usage   EXPRESS-GMapping table

A View_definition_usage is a type of View_definition_relationship that specifies a directed association between two instances of Product_view_definition.

This association represents a relationship stating that, in the definition contexts of the related instances of Product_view_definition, it is considered that the related product is used in the context of the relating product.

EXPRESS specification:

*)
ENTITY View_definition_usage
  SUBTYPE OF (View_definition_relationship);
END_ENTITY;
