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.

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.

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the date from which the classification is no longer applicable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')
