MDS Policy Constraints

REFERRING_CONNECTOR

The rightOperand will be checked against the referringConnector claim. The rightOperand needs to be a String, if multiple values are supposed to be used (e.g. with the isPartOf operator) they will need to be separated with a comma, e.g.:

"rightOperand": "MDSLXXX.XXXXX,MDSLYYY.YYYYY,MDSLZZZ.ZZZZZ,..."

If the odrl:eq operator is used, the evaluation will pass if the claim equals to the rightOperand. If the odrl:isPartOf operator is used, the evaluation will pass if the claim is contained in the rightOperand

POLICY_EVALUATION_TIME

The rightOperand needs to be a String containing a Date and Time formatted in ISO 8601, e.g.:

"rightOperand": "2025-07-20T12:34:56Z"
