To create an OV-6c Operational Event-Trace Description:
• Right-click the
Logical Architecture,
Node or
Security Domain that is to own the OV-6c Operational Event-Trace Description, point to New, point to MODAF, and then click OV-6c Operational Event-Trace Description.
For information about showing compartments on diagram symbols, setting up default view options and adding existing elements to the diagram, see the following topics:
• Click the Known Resource toolbar button, and then click in free space on the diagram. From the Select Type dialog, create or select a type to use for the Known Resource you are creating.
• From a Modeler pane, locate the Capability Configuration, Organization, Physical Architecture, Post, Resource Artifact, Role Type, Service Access or Software element that is to be the type of the Known Resource you are creating, and then drag that element to the diagram.
A Node Operation message represents an Operational Activity or Standard Operational Activity on an OV-6c Operational Event-Trace Description.
To create a Node Operation message:
• Click the Node Operation Message toolbar button, in line with the required Statement click the source lifeline, and then click the destination lifeline. The destination lifeline must be a Node Role or Problem Domain.
• Click the Node Operation Reply Message toolbar button, in line with the required Statement click the source lifeline, and then click the destination lifeline. The source lifeline must be a Node Role or Problem Domain.
When you create a Node Operation message, you are prompted to create or select the Node Operation that represents the Operational Activity or Standard Operational Activity you want to show on the OV-6c Operational Event-Trace Description.
Note that if you create a new Node Operation, you must select the represented Operational Activity or Standard Operational Activity. Modeler sets the name of the Node Operation to that of the represented Operational Activity or Standard Operational Activity.
• Click the Node Role toolbar button, and then click in free space on the diagram. From the Select Type dialog, create or select the Node or Security Domain to use as a type for the Node Role you are creating.
• From a Modeler pane, locate the Node or Security Domain that is to be the type of the Node Role you are creating, and then drag that element to the diagram. From the dialog that appears, select Node Role, and then click OK.
To create an Operational Constraint: click the Operational Constraint toolbar button, and then click in free space on the diagram.
To apply an Operational Constraint to an Operational Exchange on the diagram: click the Note Link toolbar button, click the Operational Constraint, and then click the Operational Exchange to which the Operational Constraint applies.
• Click the Operational Exchange Message toolbar button, in line with the required Statement click the source lifeline, and then click the destination lifeline.
If the types of the source and destination elements are valid for creating an Operational Exchange, you are prompted to select a conveyed classifier for the Operational Exchange.
For more information about which elements are valid source and destination elements for an Operational Exchange, see the
Operational Exchange topic.
Problem Domain elements can be created only on OV-6c Operational Event-Trace Description diagrams that are Logical Architecture owned.
To create a Problem Domain:
• Click the Problem Domain toolbar button, and then click in free space on the diagram. From the Select Type dialog, create or select the Node or Security Domain to use as a type for the Problem Domain you are creating.
• From a Modeler pane, locate the Node or Security Domain that is to be the type of the Problem Domain you are creating, and then drag that element to the diagram. From the dialog that appears, select Problem Domain, and then click OK.
To create a Service Operation message: click the Service Operation Message or Service Operation Reply Message toolbar button, in line with the required Statement click the source lifeline, and then click the destination lifeline.
When you create a Service Operation message, you are prompted to select the Service Operation you want to call. The available Service Operation elements are those Service Operation elements that are available through Request and Service ports.
In the following example, Node Role1 appears on the OV-6c Operational Event-Trace Description. When Node Role1 is the target of a Service Operation Message, Service Operation1 is available for selection.
Service Operation1 is available because the type of Node Role1 is Node2; Node2 owns the port Request1; the type of Request1 is Service Interface1; and Service Interface1 owns Service Operation1.
The following sections provide information about how an OV-6c Operational Event-Trace Description is used in the model.
Create an OV-6c Operational Event-Trace Description from
Known Resource toolbar button, and then click in free space on the diagram. From the Select Type dialog, create or select a type to use for the Known Resource you are creating.
Node Operation Message toolbar button, in line with the required Statement click the source lifeline, and then click the destination lifeline. The destination lifeline must be a Node Role or Problem Domain.
Node Operation Reply Message toolbar button, in line with the required Statement click the source lifeline, and then click the destination lifeline. The source lifeline must be a Node Role or Problem Domain.
Node Role toolbar button, and then click in free space on the diagram. From the Select Type dialog, create or select the Node or Security Domain to use as a type for the Node Role you are creating.
Operational Constraint toolbar button, and then click in free space on the diagram.
Note Link toolbar button, click the Operational Constraint, and then click the Operational Exchange to which the Operational Constraint applies.
Operational Exchange Message toolbar button, in line with the required Statement click the source lifeline, and then click the destination lifeline.
Problem Domain toolbar button, and then click in free space on the diagram. From the Select Type dialog, create or select the Node or Security Domain to use as a type for the Problem Domain you are creating.
Service Operation Message or 
Service Operation Reply Message toolbar button, in line with the required Statement click the source lifeline, and then click the destination lifeline.
