Template: EventReportItem

This section specifies the template EventReportItem.

The specification comprises a SysML Block that represents the template and an associated Parametric Diagram that defines the templates and PLCS PSM objects instantiated by the EventReportItem template.

The specification comprises the following sections:

Section Description provides a description of the template;
Section Template Block specifies the SysML Block that represents the template;
Section Template Properties specifies the properties, i.e. the Part, Reference and Value properties of the templates SysML Block;
Section Template Output Ports specifies the Output Ports of the templates SysML Block. These bind to the templates and PLCS PSM objects instantiated by the EventReportItem template as described in section Template Parametric Diagram;
Section Template Constraints specifies the constraints on PLCS PSM objects instantiated by the EventReportItem template;
Section Template Parametric Diagram specifies the templates and PLCS PSM objects instantiated by the EventReportItem template;
Section Instantiated blocks specifies the templates and PLCS PSM objects instantiated by the EventReportItem template and bound to private parts of the template;
Section Default instances species the instances that have been instantiated in the template. These are used to set the default value of blocks.
Section Constraint blocks identifies the constraint blocks that have been specified in this template;
Section Example data provides example XML data sets that have been instantiated in accordance with this template.

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

Description

The EventReportItem template describes how to represent an EventReport item. Items in an event report could be many type of things:

observed environments
observations
performed activities
proposed solutions for the problem
affected items

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

Related Templates

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

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

Template Block

Figure 2 shows the SysML Block that represents the template. The Block is an abstraction representing a pattern of templates and PLCS PSM 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.

Template Properties

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

References:

itemRoles [0..*] (Template: OASIS:Classifier)

The collection of roles for the item in the EventReport (EventReport)

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:

item [1] (Block: Ap239Ap233Psm:CollectionMemberSelect)

The item reference

effectivityRole [0..1] (Template: OASIS:Classifier)

The role (optional) of the effectivity of the item in the EventReport

Parts:

descriptions [0..*] (Template: OASIS:Descriptor)

The collection of descriptions (optional) for the event report/item relationship

Values:

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

The date (optional) when the item in the EventReport starts to be valid

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

The date (optional) when the item in the EventReport ends to be valid

Template Output Ports

The following output ports are defined for this template:

eventReportMembership (Block: Ap239Ap233Psm:CollectionMembership)

Enables the Block: Ap239Ap233Psm:CollectionMembership instantiated by this template to be referenced when the template is used.

Template constraints

There are no constraints defined for this template.

Template Parametric diagram

This section describes the template's Parametric Diagram. The diagram details the pattern of templates and PLCS PSM objects that are required to represent the template EventReportItem.

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 the Parametric Diagram.

PLCS PSM objects are shaded khaki and template shaded light green in a Parametric Diagram.
