OV-2 Operational node definition (UPDM - MODAF aliases)
Creation
To create an OV-2 Operational Node Definition:
• Right-click the Architectural Description or Service Description that is to own the OV-2 Operational Node Definition, point to New, point to Diagram, point to MODAF, and then click OV-2 Operational Node Definition.
Purpose
On an OV-2 Operational Node Definition:
• Create Energy, Logical Architecture, Node and Security Domain elements and create Generalizations to define inheritance between them.
• Create Operational Exchange links.
• Create Operational Constraint elements and apply them to Node and Security Domain elements.
• Create Service Policy elements and apply them to Logical Architecture, Node and Security Domain elements.
