In the NewReleaseMessage it is possible to communicate a
RightsClaimPolicy. Its structure has changed between different versions of ERN and users should be aware of these differences:
In versions 3.7, 3.7.1 and 3.8, a
RightsClaimPolicy comprises of one mandatory
Condition composite and one mandatory
RightsClaimPolicyType allowed value set.
However this approach was found to be buggy and, as a consequence, ERN 3.8.1 was published where the
Condition composite can now be provided multiple times, allowing several
Conditions (or none) to be linked to a single policy. The
Condition also now allows the signalling of whether the baseline for the evaluation of the
Condition is the
ReferenceResource or the
Schema in Versions 3.7.x, 3.8 and 3.8.1
Schema in Version 3.8.2 and ERN-4
Below is an example for a RightsClaimPolicy which requests the DSP to report if 50% if the track found matches the reference resource and to block access if 75% are found.
