Template Class definitions:

The ProxyItem template describes how to represent the fact that an object is the same as an object in reference data.

The SysML Block Definition diagram in Figure 1 shows how proxies are represented in the PLCS PSM.

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

References:

individual [1] (Block: Ap239Ap233Psm:ProxyItemSelect)

a reference to the individual for which a proxy is identified

the person or organization that applied the proxy relationship

Values:

startDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)

the date from which the proxy relationship 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the date from which the proxy relationship is no longer applicable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')
