Template: OASIS:Envelope

This section specifies the template Envelope.

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 Envelope template.

The specification comprises the following sections:

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

The Envelope template describes how to represent an Envelope and the message it contains.

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

Figure 1 -  Envelope model

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

NOTE    The Envelope 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.

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

References:
sender [1] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationSelect)
The organization or person in organization that sent the envelope.
recipient [1] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationSelect)
The intended receiving organization or person in organization for the envelope.
contents [1] (Template: OASIS:Message)
The message contained within the envelope.
securityClassification [0..1] (Block: Ap239Ap233Psm:SecurityClassification)
Optional - the Security Level applied to all the contents of the Envelope
Parts:
ids [1..*] (Template: OASIS:Identification)
The identifiers assigned to the Envelope.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The ids must be classified as envelope identification code.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
Values:
dateSent [1] (Block: Ap239Ap233Psm:DateTimeString)
The date or date/time when the envelope was sent.

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:

envelope (Block: Ap239Ap233Psm:Envelope)
Enables the Block: Ap239Ap233Psm:Envelope 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 Envelope.

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.

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:envelope [1] (Block: Ap239Ap233Psm:Envelope)
Private Part Property:sendAssn [1] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationAssignment)
Private Part Property:receiveAssn [1] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationAssignment)
Private Part Property:sendDateAssn [1] (Block: Ap239Ap233Psm:DateTimeAssignment)
Private Reference Property:classSenderOf [1] (Block: Ap239Ap233Psm:ExternalOwlClass)

The following constraint, normally a uniqueness constraint, is applicable when instantiating the ExternalOwlClass:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: ur1
Specification: (OCL2.0)
ExternalOwlClass::allInstances()->isUnique(class)
Private Reference Property:classRecieverOf [1] (Block: Ap239Ap233Psm:ExternalOwlClass)

The following constraint, normally a uniqueness constraint, is applicable when instantiating the ExternalOwlClass:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: ur1
Specification: (OCL2.0)
ExternalOwlClass::allInstances()->isUnique(class)
Private Reference Property:classDateSent [1] (Block: Ap239Ap233Psm:ExternalOwlClass)

The following constraint, normally a uniqueness constraint, is applicable when instantiating the ExternalOwlClass:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1
Constraint: ur1
Specification: (OCL2.0)
ExternalOwlClass::allInstances()->isUnique(class)
Private Part Property:securityClassificationAssignment [0..1] (Block: Ap239Ap233Psm:SecurityClassificationAssignment)
Private Part Property:senderClass [1] (Block: Ap239Ap233Psm:Classification)
Private Part Property:receiverClass [1] (Block: Ap239Ap233Psm:Classification)
Private Part Property:dateClass [1] (Block: Ap239Ap233Psm:Classification)
