Template: OASIS:PhysicalBreakdownStructure

This section specifies the template PhysicalBreakdownStructure.

The specification comprises a SysML Block that represents the template and an associated Parametric Diagram that defines the templates and PLCS PSMTemplate objects instantiated by the PhysicalBreakdownStructure template.

The specification comprises the following sections:

NOTE    An explanation of a template and its specification is provided in the Template overview

The FunctionalBreakdownStructure template describes how to represent a relationship between a PhysicalElementDefinition and another PhysicalElementDefinition that is a constituent.

The SysML Block Definition diagram in Figure 1 shows how a physical breakdown is represented in the PLCS PSM.

Figure 1 -  Physical Breakdown model.

No templates have been explicitly defined as being related to the PhysicalBreakdownStructure template.

NOTE    The PhysicalBreakdownStructure template may make reference to other templates as part of the Parametric Diagram. These are not listed here.

Figure 2 shows the SysML Block that represents the template. The Block is an abstraction representing a pattern of templates and PLCS PSMTemplate objects.

The properties, i.e. the SysML Block Part, Reference and Value properties, of the template's SysML Block are described in the Template Properties section.

The output ports shown on the template's SysML Block are described in the template output ports section.

The SysML Parametric diagrams for the template Block are shown in template parametric diagram section.

The following SysML Part, Reference, and Value properties are defined for this template:

References:
child [1] (Block: Ap239Ap233Psm:PhysicalElementDefinition)
The constituent PhysicalElementDefinition.
parent [1] (Block: Ap239Ap233Psm:PhysicalElementDefinition)
Parts:
ids [0..*] (Template: OASIS:Identification)
The collection of identifiers of the PhysicalElementUsage.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The id must be classified as a or a subclass thereof.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
effectivityRole [0..1] (Template: OASIS:Classifier)
A classification of the EffectivityAssignment.
structureRole [0..1] (Template: OASIS:Classifier)
A classification of the PhysicalElementUsage.
Values:
startEffectivityDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
The date that defines the lower bound of the interval of applicability.

The following constraint, normally a uniqueness constraint, is applicable when instantiating the DateTimeString:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: XSDDATETIME
Specification: (OCL2.0)
self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')
endEffectivityDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
The date that defines the upper bound of the interval of applicability. The value of the attribute need not be specified. If the value for this attribute is not specified, the interval of applicability has no upper limit.

The following constraint, normally a uniqueness constraint, is applicable when instantiating the DateTimeString:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: XSDDATETIME
Specification: (OCL2.0)
self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')

The following output ports are defined for this template:

physicalElementUsage (Block: Ap239Ap233Psm:PhysicalElementUsage)
Enables the Block: Ap239Ap233Psm:PhysicalElementUsage instantiated by this template to be referenced when the template is used.
effectivityAssignment (Block: Ap239Ap233Psm:EffectivityAssignment)
Enables the Block: Ap239Ap233Psm:EffectivityAssignment instantiated by this template to be referenced when the template is used.

There are no constraints defined for this template.

This section describes the template's Parametric Diagram. The diagram details the pattern of templates and PLCS PSMTemplate objects that are required to represent the template PhysicalBreakdownStructure.

The public properties, i.e. those visible in the template's SysML block (See Figure 2) are shown on the left of a Parametric Diagram.

NOTE    Restrictions on the reference data to be set on the public properties is defined in the Template Properties section.

The output ports are shown on the right of a Parametric Diagram.

PLCS PSM objects are shaded khaki and Templates are shaded light green in a Parametric Diagram.

The following blocks are instantiated by this template and bound to private parts of the template as shown in the Parametric Diagram section:

Private Part Property:physicalElementUsage [1] (Block: Ap239Ap233Psm:PhysicalElementUsage)
Private Part Property:datedEffectivity [0..1] (Template: OASIS:DatedEffectivity)

There are no instances that have been instantiated in this template.

There are no constraint blocks defined in this template.

No example data sets have been provided for this Template.
