An ownership link indicates that an object (example: an activity) belongs to an owner object (example: a process).

However, in certain cases we may wish to reuse the same object (an activity) in another context (in another business process). The object (the activity) will then be connected to the other context by a use link. An object can have only one owner.

So as to avoid exploring the two links to find all objects (example: the activities), a spy controller automatically connects via the use link all objects connected by the ownership link.

This mechanism exists between Business Process and Activity, Procedure and Operation, etc.
