Template: OASIS:WorkRequest

This section specifies the template WorkRequest.

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 WorkRequest template.

The specification comprises the following sections:

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

The WorkRequest template describes how to represent a request for some work to be undertaken.

The WorkRequest is one of a set of templates used to represent work and activities. These are summarized in Figure 1 which shows that the model contains templates for:

The actual templates are:

Figure 1 -  Templates representing activities

The SysML Block Definition diagram in Figure 2 shows how Work order is represented in the PLCS PSM.

Figure 2 -  Work request model

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

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

Figure 3 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.

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

References:
requestor [0..1] (Block: Ap239Ap233Psm:PersonOrOrganizationOrPersonInOrganizationSelect)
the person or organization that raised the WorkRequest
status [0..1] (Block: Ap239Ap233Psm:ProxyItemSelect)
the status of the WorkRequest.
The reference data used in Block: Ap239Ap233Psm:ProxyItemSelect is restricted as follows:
RDL constraint 1:
The status is represented subclasses of State_of_work_request.
The reference data for:
OASIS:StateAssertion.sameAs -> ExternalOwlObject.individual
is restricted to the following class or a subclass:
assignedTo [0..*] (Block: Ap239Ap233Psm:PersonOrOrganizationOrPersonInOrganizationSelect)
the person or organization that the WorkRequest has been assigned to for resolution
triggeredBy [0..*] (Block: Ap239Ap233Psm:JustificationSupportAssignmentSelect)
the reasons that lead to the WorkRequest being raised
appliesTo [0..*] (Block: Ap239Ap233Psm:WorkRequestAssignmentSelect)
the subject of the WorkRequest.
Parts:
ids [1..*] (Template: OASIS:Identification)
The identifiers assigned to the WorkRequest.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The ids must be classified as an Work_request_identification_code or a subclass thereof.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
description [0..*] (Template: OASIS:Descriptor)
An optional description assigned to the WorkRequest.
An optional description assigned to the WorkRequest
version [0..1] (Template: OASIS:Identification)
the version identifier being assigned to the WorkRequest.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The identifier must be a version identifier.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
classifications [0..*] (Template: OASIS:Classifier)
The classification of the WorkRequest.
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:
name [0..*] (Template: OASIS:Name)
An optional name assigned to the WorkRequest.
Values:
dateRequested [0..1] (Block: Ap239Ap233Psm:DateTimeString)
the date that the WorkRequest was raised.

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:

workRequest (Block: Ap239Ap233Psm:WorkRequest)
Enables the Block: Ap239Ap233Psm:WorkRequest instantiated by this template to be referenced when the template is used.
statusAsg (Block: Ap239Ap233Psm:StateAssignment)
Enables the Block: Ap239Ap233Psm:StateAssignment instantiated by this template to be referenced when the template is used.
requestorAsg (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationAssignment)
Enables the Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationAssignment instantiated by this template to be referenced when the template is used.
requestedDateAsg (Block: Ap239Ap233Psm:DateTimeAssignment)
Enables the Block: Ap239Ap233Psm:DateTimeAssignment instantiated by this template to be referenced when the template is used.
assigneeAsg (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationAssignment)
Enables the Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationAssignment 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 Diagrams. Each diagram details the pattern of templates and PLCS PSMTemplate objects that are required to represent the template WorkRequest.

The public properties, i.e. those visible in the template's SysML block (See Figure 3) 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.
