Data Items Depiction

Data items can be represented in 2 ways on the diagram, the first is a normal one, with an item Kind other than Folder, and the second a Folder which is a Data Item with an item Kind attribute equal to Folder.

Both are unique across the model. An existing data item can be dragged to a diagram from the Scope right panel.

When deleting a data item from a diagram, it will delete the data item from the model unless that data item was also used in another diagram. Make sure that you hide (right-click hide action) data items that you want to keep in your model.
