Template:— physical_breakdown_item_realization (phy_bkdn_rlzn)
Context:— UK_Defence
Date: 2009/04/17 10:29:33
Revision: 1.2

This section specifies the template physical_breakdown_item_realization.

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 reference the design realized by a physical item.

Business perspective

This information object represents the method by which a Physical Breakdown Item realizes Product_design(s), specification(s) and assembly_items.

Business object definition

This information object represents the relationship between a physical breakdown item and the product designs and / or product specifications that can be used to fulfil its requirement.

Attribute type

Optionality

ID This attribute provides the identification of the breakdown item. Identifier Mandatory
Identifier.id This is the value of the id attribute of the Identifier applied to the Physical Breakdown Item Realization. intrinsic Mandatory
Identifier.type This attribute is the type associated with the id of the Identifier given to the Physical Breakdown Item Realization. This must be one of the classes provided. Physical_breakdown_element_realization_code Mandatory

Input parameters
The following input parameters are defined for this template:
realization_id (Type='STRING')
This is the identifier of the physical breakdown item functionality relationship
realization_id_type (Default=Physical_realization_identification_code,Type='CLASS')
This attribute is provides the type associated with the id of the Identifier given to the relationship. This must be one of the classes provided.
The following classes and their sub-classes can be used:
classifications: [Physical_realization_identification_code]
[warning:]Error RDL4: The URI urn:plcs:rdl:uk_defence is not listed in dexlib/data/refdata/rdl_index.xml
id_source_organization (Type='STRING')
The identifier of the organization that owns the id. It is assumed that this will be of type Organization_identification_code and not an Organization name.
realizes (Type= 'ENTITY (Physical_element_definition)' )
This is the physical breadkdown element definition that is realizing the system.
realized_by (Type= 'ENTITY (Part_view_definition)' )
The part view definition being realized.
Reference parameters
The following reference parameters are defined for this template:
realization_relationship(Type='ENTITY (View_definition_usage)')
Allow the View_definition_usage entity instantiated in this path to be referenced when this template is used.
Note: The View_definition_usage entity can be referenced in a template path by:
%^target = $physical_breakdown_item_realization.realization_relationship%
where target is the parameter to which the View_definition_usage 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.
/representing_breakdown_element_realization(
    breakdown=@realizes,
    product=@realized_by,
    class_name='Physical_realization',
    class_ecl_id='urn:plcs:rdl:uk_defence')/
%^realization_relationship = $representing_breakdown_element_realization.bkdn_elem_real%

-- assign name to breakdown_element
/assigning_identification(
    id=@realization_id,
    id_class_name=@realization_id_type,

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_realization(realization_id='PR451', realization_id_type='Physical_realization_identification_code', id_source_organization='6421', realizes='@89', realized_by='@1')/
(an illustration of the consolidated physical_breakdown_item_realization template is shown in Figure 5 below.)
