1 Introduction

This standard was developed by the member organisations of the Digital Data Exchange, LLC (DDEX) and provides a message that gives a uniform mechanism to inform business partners of links between Sound Recordings and other Resources such as music videos, and the MusicalWorks used in those Resources. It also provides a mechanism for such links to be requested.

Any organisation wishing to implement this (or any other DDEX Standard) is required to apply for an Implementation Licence. The terms of the licence and an application form can be found here and here.
