Template: OASIS:Classifier

This section specifies the template Classifier.

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 Classifier template.

The specification comprises the following sections:

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

The Classifier template describes how to represent the classification of something.

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

Figure 1 -  Classification model

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

NOTE    The Classifier 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.

Figure 2 -  Template block definition diagram for Classifier

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

References:
class [1] (Block: Ap239Ap233Psm:ClassSelect)
the class that is being used to classify something.
classifiedBy [0..1] (Block: Ap239Ap233Psm:PersonOrOrganizationOrPersonInOrganizationSelect)
the person or organization that applied the classification.
Values:
startDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
the date from which the classification is applicable.

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')
endDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
the date from which the classification is no longer applicable

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:

classification (Block: Ap239Ap233Psm:Classification)
Enables the Block: Ap239Ap233Psm:Classification 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 Classifier.

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.

Figure 3 -  Parametric diagram for Classifier

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:classification [1] (Block: Ap239Ap233Psm:Classification)
Private Part Property:datedEffectivity [0..1] (Template: OASIS:DatedEffectivity)
Private Part Property:whoAssignment [0..1] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationAssignment)

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.

Constraints diagram
Figure 3 -  Constraint block diagram for Classifier

The following constraint blocks have been created:

Constraint: CombineClassification
Specification: (OCL2.0)
combined=classes1->union(classes2, classes3, classes4)
a constraint block that creates a collection that is the union of objects of type Classification.
Constraint: CombineClassifiers
Specification: (OCL2.0)
combined=classifier1->union(classifier2, classifier3, classifier4)
a constraint block that creates a collection that is the union of objects of type Classifier.

No example data sets have been provided for this Template.
