Communicating Links between Resources and Musical Works Message Standard
The DDEX 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 is the Communicating Links between Resources and Musical Works Standard (Linking). The message provides a mechanism for companies that have established the identity of the Musical Work or Works embodied in a Sound Recording or Video recording and enable them to inform their business partners of this fact. The message can also be used to communicate the fact that the Musical Work (or Works) identified in the message is not embodied in the Sound Recording or Video recording identified in the message.
The standard also allows companies to forward such information when they have received such information from third parties.
A detailed explanation of the Linking standard and advise about how to go about an implementation of it is available at the Knowledge Base.
