Template:- OASIS:Descriptor

The Descriptor template describes how to represent a text based description.

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

Template Properties

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

References:
context [0..1] (Block: Ap239Ap233Psm:IdentificationContextSelect)
the context in which the description has been made.
describedBy [0..1] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationSelect)
the person or organization that created the description.
Parts:
text [1] (Block: Ap239Ap233Psm:LocalizedString)
the LocalizedString representing providing the textual content of the description.
id [0..1] (Template: OASIS:Identification)
the identifications of the description
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The id must be classified as a Descriptor_identification_code or a subclass thereof.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
classifiedAs [0..*] (Template: OASIS:Classifier)
The classification of the Descriptor
The reference data used in Template: OASIS:Classifier is restricted as follows:
RDL constraint 1:
The reference data for:
OASIS:Classifier.class -> ExternalOwlClass.class
is restricted to classes that are subclasses of the following class:
Values:
startDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)
the date from which the description is valid

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 description is valid

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')
