CDM structure
The CDM has five parts:
Part 1: Architecture
This defines the file naming convention and the general architecture. This architecture is very broadly the same as is used for DSR;
Part 2: Record Type Definitions
This defines the record types that are used to make up the four file formats in Part 3 of the standard and those used for the discrepancy formats in Parts 4 and 5 of the standard;
Part 3: CDM Statements for Musical Works Claims
This defines two profiles to communicate claims and invoice details for musical works either in response to receipt of a DSR Message from a licensee or where the licensee and the licensor agree to exchange data to communicate claims details either before or after any sales and/or usage has been undertaken by the licensee on its service.;
Parts 4: Notification of Data Discrepancies
This defines one profile to communicate data discrepancies identified by a licensee that has processed a CDM Statement previously received from a licensor.
Part 5: Notification of Overclaim Discrepancies
This defines one profile to communicate overclaim discrepancies identified by a licensee that has processed a CDM Statement previously received from a licensor.
Part 6: CDM Statements for Musical Works Claims including Corrections
This define two profiles to communicate claims and invoice details for musical works, and where necessary corrections, either in response to receipt of a DSR Message from a licensee or where the licensee and the licensor agree to exchange data to communicate claims details either before or after any sales and/or usage has been undertaken by the licensee on its service.
