This template describes how to reference the system realized by a physical item\system.

This information object represents the realization of a system element by a physical item.

This information object defines the realization of a system element by a physical item.

The following section details how the physical_breakdown_item_system template can be optionally characterized by assigning other constructs to it. These are characterizations commonly applied to the template. The ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.

The following characterizations may apply:

Characterization Status Assignment

NOTE this characterization is optional.

An UK_Defence.physical_breakdown_item_system may have one or more status assigned to it, through the use of the following templates (or those based upon these): UK_Defence.status_assignment. The following template calls show how these characterizations might be instantiated.

/status_assignment(assigned_status='', assigned_status_ecl_id='', ID='', ID_type='', ID_organization='', subject='', type='', type_ecl_id='')/

Characterization Document Association

NOTE this characterization is optional.

An UK_Defence.physical_breakdown_item_system may have specific documents assigned to it, through the use of the following templates (or those based upon these): UK_Defence.document_association , and the associated UK_Defence.document . The following template calls show how these characterizations might be instantiated.

/document_association(id='', type='', source_organization='', purpose='', related_document='', related_item='')/

Characterization Applicability / effectivity

NOTE this characterization is optional.

An effectivity may be assigned to the UK_Defence.physical_breakdown_item_system. This shall be done using entity Effectivity_assignment.

For example, a dated effectivity shall be assigned using template assigning_dated_effectivity.

/assigning_dated_effectivity(start_year='2005', start_month='11', start_day='22', start_hour='15', start_minute='15', start_second='00', start_sense='ahead', start_hour_offset='2', role_class_name='Planned_effectivity', role_ecl_id='urn:plcs:rdl:std', items='@@@@')/

NOTE The type of effectivity is described through the application of reference data. In this case the reference data specifies that it is a 'Planned Effectivity', but other types can be created.
