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.
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
Product_view_definition_relationship_arm
schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Product_view_definition_relationship_arm;
(*
The following EXPRESS interface statements specify the elements
imported from the ARMs of other application modules.

NOTE 2
See Annex C,
Figures
C.1and C.2
for a graphical representation of this schema.
This subclause specifies the ARM types
for this application module. The ARM types and
definitions are specified below.
The as_product_view_definition_or_reference type allows for the designation of the data
types
Product_view_definition, and Generic_product_view_definition_reference.
EXPRESS specification:
*)
TYPE
as_product_view_definition_or_reference =
SELECT
(Product_view_definition,
Generic_product_view_definition_reference);
END_TYPE;
(*
A contextual_shape_type_enumeration is an identifier for the kind of shape for a
View_definition_relationship.
EXPRESS specification:
*)
TYPE
contextual_shape_type_enumeration =
EXTENSIBLE
ENUMERATION
OF
(unspecified);
END_TYPE;
(*
Enumerated item definitions:
unspecified:
the kind of shape is not specified.
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 View_definition_relationship is an association between two instances of Product_view_definition.

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.
shape_type:
the kind of shape.
The value of this attribute need not be specified.
primary_shape_representation:
the primary
shape_model
that represents the shape of the View_definition_relationship.
The value of this attribute need not be specified.
auxiliary_shape_representations:
additional
shape_models
that represents the shape of the View_definition_relationship for auxiliary purposes.
The value of this attribute need not be specified.
Formal propositions:
WR1:
If auxiliary_shape_representations is provided then primary_shape_representation shall be provided.
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.
