Control (UPDM - NAF aliases)
Creation
To create a Control as a link that is not realized by any elements:
• From an NSV-1 Resource Specification: click the Control Link button, click the source Organization, Post or Responsibility, and then click the destination Resource Artifact or Software.
Control Link button, click the source Organization, Post or Responsibility, and then click the destination Resource Artifact or Software.On the Select Conveyed Classifier dialog, create or select the Exchange Element that is the Control element's conveyed classifier.
• From an NSV-10c Resource Event-Trace Description, click the Control Message button, in line with the required Statement click the source lifeline, and then click the destination lifeline.
Control Message button, in line with the required Statement click the source lifeline, and then click the destination lifeline.The type of the source Resource Role must be an Organization, Post or Responsibility, and the type of the destination Resource Role must be a Resource Artifact or Software.
To create a Control that is realized by a Resource Interface or Service Channel:
• From an NSV-1 Resource Interaction Specification: click the Control button, and then click the Resource Interface or Service Channel.
Control button, and then click the Resource Interface or Service Channel.◦ For a Resource Connector: The Resource Role that owns the source Resource Port must use an Organization, Post or Responsibility as its type. The Resource Role that owns the target Resource Port must use a Resource Artifact as its type.
◦ For a Service Channel: The Resource Role that owns the source Request or Service must use an Organization, Post or Responsibility as its type. The Resource Role that owns the target Request or Service must use a Resource Artifact as its type.
On the Select Type dialog, create or select the Exchange Element that is the Control element's conveyed classifier. On the context menu, irrespective of which command you click, the destination of the Control will be set to the Resource Role that uses a Resource Artifact as its type.
To create a Control that is realized by a Resource Connector:
• From an NSV-2 System Communications Description: click the Control button, and then click the Resource Connector.
Control button, and then click the Resource Connector.The source Resource Role must use an Organization, Post or Responsibility as its type. The target Resource Role must use a Resource Artifact or Software as its type.
On the Select Conveyed Classifier dialog, create or select the Exchange Element that is the Control element's conveyed classifier.
 | When you create a Control on a Resource Connector, a context menu allows you to choose the direction of the Control. However, irrespective of which command you click, the destination Control will always be the Resource Role that uses a Resource Artifact or Software as its type. |
To create a Control that is realized by a Function Edge (Control Flow) or Function Edge (Object Flow):
• From an NSV-4 Functionality Description: click the Control button, and then click the Function Edge (Control Flow) or Function Edge (Object Flow).
Control button, and then click the Function Edge (Control Flow) or Function Edge (Object Flow).From the dialogs that appear, select the conveyed classifier, the source Organization, Post or Responsibility of the Control, and then the destination Resource Artifact or Software of the Control.
The direction of the Control is set to the direction of the Function Edge (Control Flow) or Function Edge (Object Flow) that realizes the Control.
You can convert a Control to a Command or Resource Interaction: right click the Control, point to Convert To, and then click the required command.
Realizing Elements
A Control can be realized by many Resource Connector, Resource Interface, Function Edge (Control Flow), Function Edge (Object Flow) and Service Channel elements.
To define that a Control is realized by an element:
• Drag the Control from a Modeler pane to the Resource Connector, Resource Interface, Function Edge (Control Flow), Function Edge (Object Flow) or Service Channel on a diagram.
• Drag the Control element's conveyed classifier from a Modeler pane to the Resource Connector, Resource Interface, Function Edge (Control Flow), Function Edge (Object Flow) or Service Channel on a diagram. On the Select Control dialog, select the Control.
• Right-click the Resource Connector, Resource Interface, Function Edge (Control Flow), Function Edge (Object Flow) or Service Channel, point to Links, point to Realized, and then click Control. From the dialog, select the Control elements that realize the element you right-clicked.
If you right-click the Resource Connector, Resource Interface, Function Edge (Control Flow), Function Edge (Object Flow) or Service Channel on a diagram, the Control elements you select are added to the diagram.
You can view which elements realize a Control on the Items tab of its Property Pages. In the Show Associated list, select Realization. Do not define realized elements through the Items tab.
When a Control is realized by an element, you can change the source and target elements of the Control to those of the realized element: on a diagram that shows the Control on the realized Resource Connector, Resource Interface, Function Edge (Control Flow), Function Edge (Object Flow) or Service Channel, right-click the Control, and then click Set Ends to Realizing Link Ends.
Appearance
When shown on an NSV-1 Resource Specification, a Control Link appears as follows:
When shown on an NSV-1 Resource Interaction Specification, NSV-2 System Communications Description or NSV-4 Functionality Description, a Control realization appears as follows:
An NSV-3 Resource Interaction Matrix shows how elements are related through Control relationships.
Relationships
There are no relationships that are of significant importance to a Control.
