Example Use Case: The below Set Policy type states that the Asset http//example.com/asset:9898 is the target of the Permission to perform the action reproduce, the Duty to perform the action attribute to http://example.com/owner:9898, and the Prohibition to perform the action translate. Two Parties are involved, namely the Assigner of the Permission and the Party to be attributed.

As multiple Assets, Parties, and Actions can be expressed for each Rule, then the following (snippet) example shows two Assets defined for the policy:

Policy Conflict Strategy

 
Example Use Case: Two Policies are associated to the same target Asset http://example.com/asset:1212. The first Policy http://example.com/policy:0001 allows to use the Asset. The second Policy http://example.com/policy:0002 allows for the display of the Asset, but it prohibits print. Both policies explicitly state how to deal with conflicts through the conflict attribute being set to perm. Hence the Permissions will always override any Prohibitions. In this use case, since the print Action is a subset of the use Action, there could be a conflict. However, the perm conflict strategy means that the use Permission will override the print Prohibition.

Example Use Case: The Policy below shows a Permission to distribute photos in which the first constraint (the event http://example.com/football/game/2017) has concluded (the operator odrl:gt indicating this), then the second constraint (wait for 60 minutes) has passed. The operator andSequence requires that first the constraint in the leftOperand is satisfied - the event has closed - and this triggers the Action Delay Period after which the action of the permission may be excercised. (Note: The operator value of andSequence is not the same as  and as for the latter, both operand Constraints must be satisfied, but could be processed at the same time.)
