This clause specifies the information requirements for the
Incomplete data reference mechanism
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
Incomplete_data_reference_mechanism_arm
schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Incomplete_data_reference_mechanism_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:
| Classification_assignment_arm |
ISO/TS 10303-1114 |
| Document_definition_arm |
ISO/TS 10303-1123 |
| Part_view_definition_arm |
ISO/TS 10303-1023 |
NOTE 2
See Annex C,
Figures
C.1and C.2
for a graphical representation of this schema.
This subclause specifies the ARM type
for this application module. The ARM type and
definition is specified below.
The idrm_marked_item type is an extension
of the
classification_item type.
It adds the data
types
Digital_document_definition, Digital_file, and Part_view_definition
to the list of alternate data types.
EXPRESS specification:
*)
TYPE
idrm_marked_item =
SELECT
BASED_ON
classification_item
WITH
(Digital_document_definition,
Digital_file,
Part_view_definition);
END_TYPE;
(*
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.
An Incomplete_reference_marking is a type of Classification_assignment that assigns a particular marking to instances of an entity type selected in the idrm_marked_item select type.
This marking specifies that each of these instances are partly transferred in the exchange structure.
EXAMPLE
If applied to an instance of Digital_file, then this marking indicates that the external file that should be provided with the Digital_file in the transferred data package, is not provided.
This prevents the need for repeated transfers of a big file between partners when its content has not changed.
EXPRESS specification:
*)
ENTITY Incomplete_reference_marking
SUBTYPE OF (Classification_assignment);
SELF\Classification_assignment.items : SET[1:?] OF idrm_marked_item;
WHERE
WR1: SELF\Classification_assignment.assigned_class.id = 'reference';
END_ENTITY;
(*
Attribute definitions:
items:
the set of
idrm_marked_items
an Incomplete_reference_marking can be assigned to.
Formal propositions:
WR1:
The marking shall only be applied to instances of an entity type selected in the idrm_marked_item select type.
