[Mick Bass] how relationships among the information could/should be expressed .... And here is the required context information, including links to the diagrams that were being discussed [wmj] What kind of relationships is represented by black and red arcs in the diagrams? I am converting/rewriting such diagrams into another notations which "demands" such spec.
