This section specifies the template representing_breakdown.
NOTE
An explanation of a template and the associated instantiation path is
provided in the
Template overview
section.
The EXPRESS-G diagram in
Figure
1
shows the templates and EXPRESS entities that are required
to represent the template
"representing_breakdown".
The text highlighted in blue shows the template parameters.
Grey areas and templates with dashed lines are not included in the template, but may be used to further
characterize the template.

The graphic for the template to be used in other EXPRESS-G diagrams
is shown in Figure

below.

The following input parameters are defined for this template:
The identifier of the Breakdown.
The name of the class being used to classify the identification
(
Identification_assignment)
of the breakdown. This provides the role or reason for the identification.
The following classes and their sub-classes can be used:
id_ecl_id (Default=urn:plcs:rdl:std,Type='URN')
The identifier of the
External_class_library
storing the definition of the class referenced by the parameter @id_class_name class.
The name or identifier of the organization owning the id or name.
The name of the class being used to classify the
identification of the organization. For example CAGE code, or organization name.
The following classes and their sub-classes can be used:
The name of the class being used to classify the
Breakdown.
The following classes and their sub-classes can be used:
The identifier of the
External_class_library
storing the definition of the class referenced by the parameter @bkdn_type class.
vn_id (Default=Unknown,Type='STRING')
The identifier of the Breakdown_version.
The name of the class being used to classify the identification
(
Identification_assignment)
of the breakdown version. This provides the role or reason for the identification.
The following classes and their sub-classes can be used:
The identifier of the
External_class_library
storing the definition of the class referenced by the parameter @vn_id_class_name class.
The name or identifier of the organization owning the @vn_id.
The name of the class being used to classify the
identification of the organization. For example CAGE code, or organization name.
The following classes and their sub-classes can be used:
The product that have been broken down.
The following reference parameters are defined for this template:
Allow the
Breakdown
entity instantiated in this path to be referenced when this template is used.
Note: The
Breakdown
entity can be referenced in a template path by:
%^target = $representing_breakdown.bkdn%
where
target
is the parameter to which the
Breakdown
is bound.
Allow the
Breakdown_version
entity instantiated in this path to be referenced when this template is used.
%^target = $representing_breakdown.bkdn_vn%
Allow the
Breakdown_of
entity instantiated in this path to be referenced when this template is used.
Note: The
Breakdown_of
entity can be referenced in a template path by:
%^target = $representing_breakdown.bkdn_of%
where
target
is the parameter to which the
Breakdown_of
is bound.
The following parameter combinations specify a uniqueness constraint:
Unique constraint: External id class for Breakdown
Unique constraint: External id class for Breakdown_version
The instantiation path shown below specifies the entities that are to be
instantiated by the template.

The following entities are instantiated with attributes as specified:
The instance diagram in Figure
3
shows an example of the EXPRESS entities and templates that are instantiated by the template:
/representing_breakdown(id='Breakdown of the bike', id_class_name='Breakdown_name', id_ecl_id='urn:plcs:rdl:std', id_owner='Express Delivery Inc', id_owner_class_name='Organization_name', id_owner_ecl_id='urn:plcs:rdl:std', bkdn_type='LSI breakdown', bkdn_type_ecl_id='urn:plcs:rdl:sample', vn_id='A', vn_id_class_name='Version_identification_code', vn_id_ecl_id='urn:plcs:rdl:std', vn_id_owner='Express Delivery Inc', vn_id_owner_class_name='Organization_name', vn_id_owner_ecl_id='urn:plcs:rdl:std', of_product='#4')/
(an illustration of the consolidated representing_breakdown template is shown in
Figure
4 below.)
Note that the
assigning_reference_data and
assigning_identification templates are used in the diagram.
Namely:
/assigning_reference_data(items='#1', class_name='LSI breakdown', ecl_id='urn:plcs:rdl:sample')/
/assigning_identification(items='#1', id='Breakdown of the bike', id_class_name='Breakdown_name', id_ecl_id='urn:plcs:rdl:std', org_id='Express Delivery Inc', org_id_class_name='Organization_name', org_id_ecl_id='urn:plcs:rdl:std')/
/assigning_identification(items='#2', id='A', id_class_name='Version_identification_code', id_ecl_id='urn:plcs:rdl:std', org_id='Express Delivery Inc', org_id_class_name='Organization_name', org_id_ecl_id='urn:plcs:rdl:std')/

The instance diagram in
Figure
4
shows the graphic symbol for the template that is to be
used in other instance diagrams. The example template is:
/representing_breakdown(id='Breakdown of the bike', id_class_name='Breakdown_name', id_ecl_id='urn:plcs:rdl:std', id_owner='Express Delivery Inc', id_owner_class_name='Organization_name', id_owner_ecl_id='urn:plcs:rdl:std', bkdn_type='LSI breakdown', bkdn_type_ecl_id='urn:plcs:rdl:sample', vn_id='A', vn_id_class_name='Version_identification_code', vn_id_ecl_id='urn:plcs:rdl:std', vn_id_owner='Express Delivery Inc', vn_id_owner_class_name='Organization_name', vn_id_owner_ecl_id='urn:plcs:rdl:std', of_product='#4')/

The following section details how the
representing_breakdown
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 General
NOTE this characterization is optional.
Any Breakdown
may be characterized in several ways. None of those are specific to
Breakdowns, and therefore
not discussed in detail here.
The following is a few examples of such general characterizations.
Breakdowns
and Breakdown_versions
can be characterized by:
-
Activities and Activity_methods (including Task_method and Scheme).
-
States, e.g. for life cycle status assignments.
-
Date, time and effectivities.
-
Documents.
-
Organizations and persons, e.g. to identify owner or creator.
-
Projects and contract assignments.
-
Requirements.
-
etc.
