We double click on the JDF Navigator tab to show the Navigator Pane with the full width of the window. We expand the Assembly resource. The (3,0,5,0) following “Assembly” means there are 3 referencing resources under “Referenced by Elements” (Component, CutBlock and PageList), (Note that CutBlock is Referenced by CuttingParams which is input to Cutting) Input to the Cutting process). 0 referencing messages, 5 inputs to processes under “Input to Processes” (Collecting, Gathering, GB ImpositionPreparation, Stripping and WebInlineFinishing). 0 outputs from processes. The Definition icon contains the definition of the item (Assembly and Cutting in this case) for drilling down into the structure. The {1} after Assembly means there is one Definition of Assembly.
