Template: SwedishDefence:PropertyValue

This section specifies the template PropertyValue.

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 PropertyValue template.

The specification comprises the following sections:

NOTE    An explanation of a template and its specification is provided in the Template overview
The PropertyValue template describes how to represent a value of an operational property definition that is registered at a certain time for a specific item of supply individual, or that is defined as an allowed value for the property.

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

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

Figure 1 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 constraints shown on the template's SysML Block are described in the template constraints section.

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

Figure 1 -  Template block definition diagram for PropertyValue

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

References:
operationalPropertyDefinition [1] (Template: SwedishDefence:OperationalPropertyDefinition)
Reference to the operational property definition for which this property value represents one measurement.
unit [0..1] (Block: Ap239Ap233Psm:ExternalUnit)
An external unit (OWL individual) representing the measurement unit for the property value.

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

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: UR1
Specification: (OCL2.0)
ExternalUnit::allInstances()->isUnique(definition)
Values:
numericalValue [0..1] (Real)
Value of the property (if numerical, use textValue othervise).
textValue [0..1] (String)
Value of the property (if text, use numericalValue othervise).

The following output ports are defined for this template:

PSMpropertyValue (Block: Ap239Ap233Psm:PropertyValue)
Enables the Block: Ap239Ap233Psm:PropertyValue instantiated by this template to be referenced when the template is used.

The following constraints are defined for this template:

Constraint: textOrNumeric
Specification: (OCL2.0)
textValue.oclIsUndefined () xor numericalValue.oclIsUndefined ()
Constraint: unitRequired
Specification: (OCL2.0)
unit.oclIsUndefined () = numericalValue.oclIsUndefined ()
Constraint: validUnit
Specification: (OCL2.0)
operatalPropertyDefinition.allowedUnits->isEmpty() xor operatingPropertyDefinition.allowedUnits->include(unit)

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 PropertyValue.

The public properties, i.e. those visible in the template's SysML block (See Figure 1) 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.

Figure 2 -  PropertyValue

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:pvt [0..1] (Template: OASIS:PropertyValueText)
Private Part Property:localizedString [0..1] (Block: Ap239Ap233Psm:LocalizedString)
Private Part Property:pvn [0..1] (Template: OASIS:PropertyValueNumeric)
Private Part Property:select [1] ( Constraint Block: SwedishDefence:PropertyValue:ChooseValue)
Protected Part Property:pv [1] (Block: Ap239Ap233Psm:PropertyValue)

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

Figure 3 shows the constraint blocks that have been created in the template.

Constraint Blocks are typically used to combine blocks into a collection that can then be bound to a property. For example, combining a set of identifications that can then be bound to property of type Identification.

The following constraint blocks have been created:

Constraint: ChooseValue
Specification: (OCL2.0)
selected = if val1.oclIsUndefined () then val2 else val1 endif

No example data sets have been provided for this Template.
