This clause specifies the information requirements for the
Property 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
Property_assignment_arm
schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Property_assignment_arm;
(*
The following EXPRESS interface statements specify the elements
imported from the ARMs of other application modules.
EXPRESS specification:

NOTE 1
The schemas referenced above are specified in the following
part of ISO 10303:
| Activity_arm |
ISO/TS 10303-1047 |

ISO/TS 10303-1006 |
| Independent_property_arm |

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 pa_activity_item type is an extension
of the
activity_item type.
It adds the data
type
Property_definition_relationship
to the list of alternate data types.
EXPRESS specification:
*)
TYPE
pa_activity_item =
SELECT
BASED_ON
activity_item
WITH
(Property_definition_relationship);
END_TYPE;
(*
The property_assignment_select type is an
extensible list of alternate data types.
Additional alternate data types are specified in select data
types that extend the
property_assignment_select type.
NOTE 1
This empty extensible select requires
extension in a further module to ensure that entities that refer to it have
at least one valid instantiation.
NOTE 2
Extensions of this SELECT data type, primarily designed to specify the list of entity data types to which properties can be
assigned,
are constrained by the existence of resource entities to represent in the MIM schema such an assignment and by the semantics
of these entity data types.
In particular:
-
assignment of properties to activity related data types is represented with the resource entity action_property
which is found in the application module Process property assignment;
-
data types that are subtypes of entity data types Representation
and Representation_item
shall not be added in any extension of this SELECT data type,
as they provide elements of representation of a property and are not expected to have properties.
EXPRESS specification:
*)
TYPE
property_assignment_select =
EXTENSIBLE
GENERIC_ENTITY
SELECT;
END_TYPE;
(*
The represented_definition type is an
extensible list of alternate data types
that allows for the designation of the data
types Independent_property and Assigned_property.
NOTE
The list of entity data types may be
extended in application modules that use the constructs of
this module.
EXPRESS specification:
*)
TYPE
represented_definition =
EXTENSIBLE
GENERIC_ENTITY
SELECT
(Independent_property,
Assigned_property);
END_TYPE;
(*
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.
An Applied_independent_property is a type of Assigned_property
that is associated
with an Independent_property.
It characterizes the fact that the Applied_independent_property
is the application of the Independent_property
to product data.
EXPRESS specification:
*)

Attribute definitions:
base_independent_property:
the Independent_property
from which the type of the Assigned_property
is derived.
name:
the words by which the Applied_independent_property is known. It is derived from the property_type
of the associated Independent_property.
An Applied_independent_property_relationship is a relationship between two

An Assigned_property is a property that is assigned to product data.
NOTE
The mapping provided for that entity and for its attribute described_element is incomplete.
It needs to be completed in any module that uses this module and extends the type property_assignment_select.
