Edit an edge in a diagram view

You can edit an edge of a node in a diagram view.

Steps

  1. Open a diagram view.
  2. Click .
    The General properties form appears.
  3. Do one of the following:
    • Select an edge in the diagram.
    • Select a node in the diagram and click next to an incoming or outgoing edge in the edge section.
    The Edge properties form appears.
  4. Enter the required information.
    FieldDescription
    Relation type

    Select a relation type to define the relation type of the currently selected edge.

    The drop-down list shows all available directed relation types.

    Role direction

    Indicates the direction in which instances of this relation type are traversed.

    • Selected: The edge is traversed from head to tail. The edge label is the role of the relation type.
    • Cleared: The edge is traversed from tail to head. The edge label is the co-role of the relation type.
    from

    Select the node from which the edge starts.

    In the drop-down list of nodes, the nodes that match the current type of edge are shown first (under Matching types). Nodes that do not match the current type are shown after the matching types (under All types). It is also indicated if the node is already in the diagram (on diagram).

    A matching node is (a parent of) the head asset type of the current relation type (when Role direction is selected) or (a parent of) the tail asset type of the relation type (when Role direction is cleared).

    Selecting a node that is already in the diagram view adds this edge to that node.

    Selecting a node that is not yet in the diagram view adds this node to the view.

    to

    Select the node in which the edge ends.

    You must select an ID from the drop-down list of nodes. The list contains nodes that match the current type of edge.

    A matching node is (a parent of) the tail asset type of the current relation type (when Role direction is selected) or (a parent of) the head asset type of the relation type (when Role direction is cleared).

    Selecting a node that is already in the diagram view adds this edge to that node.

    Selecting a node that is not yet in the diagram view adds this node to the view.

    Style

    Select the style of the edge.

    • Arrow: An arrow from the outgoing side to the incoming side. The pointer is on the incoming side of the arrow. This is the default setting.

      Business Asset is the selected node.

    • Boxed: The node on the outgoing side is enclosed by the node on the incoming side.

      Business Asset is the selected node. It is boxed by Employee.

    • Boxing: The node on the outgoing side encloses the node on the incoming side.

      Business Asset is the selected node. It is boxing Employee.

    Label

    Type a label for the edge.

    If you do not specify a label, either the role or co-role name of the relation type from the operating model is used in both the diagram view and the diagram.

    If the Role direction check box is selected, the label is the role of the relation. If it is cleared, it uses the co-role.

  5. Above the diagram, to the right, click Save.
