In this section we will model our “User Administration” example as introduced in the Introduction chapter. You should try to build a graph with a structure as shown in the following figure.
The repository of the sample application of this chapter holds all needed node and edge types. Here is a step-by-step guide for your first modeling steps:
Drag an Application node (the leftmost) from the repository to the graph document. Double-click in the lower part of this node an type “1”. The editing process is terminated by clicking in an empty area of the document or by pressing STRG + ENTER.
Drag a Right and a Rule node (next to the Application node) into the graph document. Double-click in the lower part of these nodes and type “Read_X” for the Right node and “Developer” for the Role node.
Connect the Application node with the Right node. To do so, activate the edge-creation-mode. This is done by clicking the corresponding toggle button in the toolbar:
Now move the mouse cursor over the Application node and drag to the Right node. You have created a contain edge. Do the same for the Role node.
Connect the Right and Rule node (in this direction) with an assigned to edge. To do so click on the toggle button labeled “CO” right from the edge-creation-mode toggle button. The label switches to “AS”. Now drag your edge and a new assigned to edge is created.
You should have all you need to create the remaining part of the sample graph. Have fun!
