Dear Robert,Attached how I would model your use cases now. Simply and deliberately, the CRM describes rights so far only as current state. Note that the triangle P75,P104, P105 circumscribes a state of "Right Holding" in the centre of the triangle, which would carry a time interval. If we introduce this class, P75,P104, P105 become shortcuts of three new properties connecting the rights holding to the corners.
I post this as issue, if this should be added to the CRM. I'd personally prefer to work on adequate extensions, because all the world of contracts, laws, business transactions and obligations, plans etc. could be dealt with more coherently separate from the material world view. What about a "CRM social"?
