Control (UPDM - MODAF aliases)
Creation
To create a Control as a link that is not realized by any elements:
On the Select Conveyed Classifier dialog, create or select the
Exchange Element that is the Control element's conveyed classifier.
To create a Control that is realized by a
Resource Interface or
Service Channel:
◦ For a Service Channel: The Resource Role that owns the source
Request or
Service must use an
Organization,
Post, or
Role Type 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:
On the Select Conveyed Classifier dialog, create or select the
Exchange Element that is the Control element's conveyed classifier.
Note that 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.
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
SV-1 Resource Definition, a Control Link appears as follows:
An
SV-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.
