Application module: Incomplete data reference mechanism | ISO/TS 10303-1349:2019(E) © ISO |
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.

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.
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.
