This section specifies the template physical_breakdown_item.

NOTE The template has been defined in the context of UK_Defence. Refer to the business context for details of related templates.

NOTE An explanation of a template and the associated instantiation path is provided in the Template overview section.

Description

This template describes how to represent the UK_Defence concept of a physical breakdown element in terms of PLCS model elements (templates, entities, and reference data).

Business perspective

This information object represents the identification of, and the reference to, a physical components in a breakdown.

Input parameters

The following input parameters are defined for this template:

id (Type='STRING')

The identifier of the physical breakdown item.

description (Type='STRING', Optional)

The description of the physical breakdown item.

name (Type='STRING')

The name of the physical breakdown item.

source_organization (Type='STRING')

The organization or information system that created the associated identifier. Alternatively this could be set to /NULL and when Person or Information System is the source; see Identifier template characterizations.

type (Default=Physical_breakdown_item_type,Type='CLASS', Optional)

The type of the physical breakdown item. Sub-classifications of Physical_breakdown_item_type should be identified by and between organizations as necessary to match the business requirements.

The following classes and their sub-classes can be used:

classifications: [Physical_breakdown_item_type]

Error RDL4: The URI urn:plcs:rdl:uk_defence is not listed in dexlib/data/refdata/rdl_index.xml

version (Type='STRING')

The identifier of the physical breakdown item version.

contained_by_breakdown (Type= 'ENTITY (Physical_breakdown_version)' )

The breakdown version that contains this element.

Reference parameters

The following reference parameters are defined for this template:

phys_item(Type='ENTITY (Physical_element)')

Allow the Physical_element entity instantiated in this path to be referenced when this template is used.

Note: The Physical_element entity can be referenced in a template path by:

%^target = $physical_breakdown_item.phys_item%

where target is the parameter to which the Physical_element is bound.

phys_item_vn(Type='ENTITY (Physical_element_version)')

Allow the Physical_element_version entity instantiated in this path to be referenced when this template is used.

Note: The Physical_element_version entity can be referenced in a template path by:

%^target = $physical_breakdown_item.phys_item_vn%

where target is the parameter to which the Physical_element_version is bound.

phys_item_def(Type='ENTITY (Physical_element_definition)')

Allow the Physical_element_definition entity instantiated in this path to be referenced when this template is used.

Note: The Physical_element_definition entity can be referenced in a template path by:

%^target = $physical_breakdown_item.phys_item_def%

where target is the parameter to which the Physical_element_definition is bound.

phys_item_def_cntxt(Type='ENTITY (View_definition_context)')

Allow the View_definition_context entity instantiated in this path to be referenced when this template is used.

Note: The View_definition_context entity can be referenced in a template path by:

%^target = $physical_breakdown_item.phys_item_def_cntxt%

where target is the parameter to which the View_definition_context is bound.

phys_item_cntxt(Type='ENTITY (Physical_breakdown_context)')

Allow the Physical_breakdown_context entity instantiated in this path to be referenced when this template is used.

Note: The Physical_breakdown_context entity can be referenced in a template path by:

%^target = $physical_breakdown_item.phys_item_cntxt%

where target is the parameter to which the Physical_breakdown_context is bound.

Instantiation path

The instantiation path shown below specifies the entities that are to be instantiated by the template.

A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.

Instance diagrams

The instance diagram in Figure 4 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/physical_breakdown_item(id='P301 451', description='support bracket', name='bracket', type='Physical_breakdown_item_type', source_organization='6421', version='issue 4b', is_contained_by='@74')/

(an illustration of the consolidated physical_breakdown_item template is shown in Figure 5 below.)

The instance diagram in Figure 5 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:

/physical_breakdown_item(id='P301 451', description='support bracket', name='bracket', type='Physical_breakdown_item_type', source_organization='6421', version='issue 4b', is_contained_by='@74')/

Characterizations

No common characterizations of the template physical_breakdown_item have been identified. However, the ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.
