Okay, thanks for that link. With the dublin core vocabulary instead of 
the "Rightsholder" i agree.

Yes, i think they should be bi-directional (or instead nondirectional). 
I think both these both relations are possible:
- The Permission is given (or granted) by a Party (even the Rightsholder).
- The party grants that Permission. (Or in according to the acutal 
core-model: Some Party could be the Assigner of any Permission)

I think the function-attribute of Role (even "Assigner"/"Assignee") 
forces the link-direction of Party between Permission/Prohibit/Duty.

Or is there a reason for the left out Party-to-Permission/Prohibit/Duty 
relation?
