The Musical Work Notification request/response choreography supports a number of use cases. These include:
- A licensee requesting information on a licensor's claim(s) to musical work(s)
- A licensee wanting to augment and enrich the data they have on musical work(s)
It should be noted that first use-case may be the first step in a larger process of a licensee requesting licence(s) for use(s) of musical-work(s).
As well as the share information at the heart of the process, the choreography allows for (and indeed encourages) the exchange of many data elements which should provide significant value to both licensor and licensee. In particular, the process allows for the licensee to supply sound-recording and release data to the licensee, along with the associated, ISRCs, UPCs, catalogue numbers etc. In exchange, the licensor can supply the licensee with IPI, ISWC and other similar works data.
As well as industry standard identifiers, it is also highly recommended that both licensee and licensor ingest each other's proprietary identifiers. Exchange and usage of identifiers allows for much greater automation of this and other licensing processes.
A sample MWN Request Message is available here. Depending on the circumstances, the response can look very different:
- The licensor may have an interest in the work, and will describe its interest in the response. Clearly, the complexity of the ownership can vary greatly and can range from
- The licensor has no interest in the work, and the work is in the licensor's system; or
- The licensor has no interest in the work, and the work is *not* in the licensor's system.
Core Concepts
Many of the concepts listed below will be familiar to most readers already, but a common understanding of core concepts is essential for the ensuring that all implementations of the DDEX standards are coherent:

Many of the identifiers listed below will be familiar to most readers already, but a little more information follows on identifiers that may be less familiar:
MWN and the Common Works Registration (CWR)
There is some overlap between DDEX's MWN standard and the Common Works Registration (CWR). Details on this overlap are detailed here.
