The DDEX RDR Message Suite Standards are relevant for the communication with and between music licensing companies. In the past, a variety of different and largely incompatible formats were used with and between MLCs.

The DDEX RDR Message Suite Standards is for use by:


Comprehensive implementation of the DDEX RDR Message Suite Standards will improve the efficiency and the accuracy of the distribution of revenues to rights holders.

The following processes are or will be supported by the DDEX RDR Message Suite Standards:

  1. Record companies send information about sound recordings to an MLC using the Recording Data and Rights Notification Standard (RDR-N);
  2. MLCs share repertoire information between each other also using the RDR-N;
  3. A standard will be added to the suite of standards that enables MLCs to exchange sales and revenue data between each other which will be called the Recording Data and Rights Revenue Reporting Standard (RDR-R);
  4. Similarly, the RDR-R standard once published will enable MLCs to send revenue information to the owners of the sound recordings, i.e. the labels; and
  5. The choreographies, whereby RDR-N and RDR-R messages are exchanged between companies will be published as the Recording Data and Rights Choreography Standard (RDR-C), although a choreography already exists in the Music Licensing Companies Message Suite and Choreography Standard (Version 1.4).


The exchange of data between MLCs is necessary to meet the requirements of bilateral agreements between the MLCs that administer the rights of producers and performers across multiple territories. This includes data about sound recordings, music videos and related sales data used within rights administration.
