Node role (UPDM - MODAF aliases)
Creation
To create a Node Role:
From a Logical Architecture, Node or Security Domain or: right-click the element, point to New, point to MODAF, and then click Node Role.
On the Select Type dialog, create or select the Node or Security Domain that is the type of the Node Role, or create an untyped Node Role.
From an OV-2 Operational Node Definition: click the Node Role toolbar button, and then click the owning Logical Architecture, Node or Security Domain.
On the Select Type dialog, create or select the Node or Security Domain that is the type of the Node Role.
From an OV-2 Operational Node Relationship Description:
Click the Node Role toolbar button, and then click the Logical Architecture, Node, Node Role, Problem Domain, or Security Domain element that is to own the Node Role. On the Select Type dialog, create or select the Node or Security Domain that is the type of the Node Role, or create an untyped Node Role.
If the owner of the OV-2 Operational Node Relationship Description is not shown on the diagram, create a Node Role on the diagram owner by clicking in free space.
From an appropriate Modeler pane, locate the Node or Security Domain that you want to use as the type of the Node Role, and then drag that Node or Security Domain to the owning Logical Architecture, Node, Node Role, Problem Domain or Security Domain element on the diagram. If a dialog is displayed, select Node Role, and then click OK.
If the owner of the OV-2 Operational Node Relationship Description is not shown on the diagram, create a Node Role on the diagram owner by dragging the type to free space.
Note that when you create a Node Role on a Node Role or Problem Domain, the Node Role is created on the type of the Node Role or Problem Domain.
From an OV-6c Operational Event-Trace Description:
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, or create an untyped Node Role.
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.

Relationships
The following relationships are of importance to a Node Role:
Needline relationships link a Node Role to Known Resource, Node Port, Node Role and Problem Domain elements.
