The Electronic Release Notification Message Suite Standard (informally called the "Release Notification Message Standard", see URL) is one of several XML message formats published by DDEX. Release notifications are messages that record labels or aggregators send to distributors to inform them of new releases that are available for distribution, and the terms and conditions under which such releases can be made available.
The Release Notification Message Standard addresses the problem of a record company or aggregator having to send its products to distribution partners in multiple formats. It can be used for everything from a single release with a single deal, to the communication of a sales campaign that includes price changes over the course of time. Its three main elements are Resources, Releases, and Deals. Resources are the primary assets such as audio or video tracks, and also secondary assets such as cover images and PDF booklets. Releases are the principal products that encompass the resources, and Deals are the descriptions that define how a Release may be used.
