Short answer
DDEX (Digital Data Exchange) is a not-for-profit standards organization, formed in 2006, that defines the message formats music companies use to exchange data in the digital supply chain. Its best-known standard is the Electronic Release Notification (ERN), the XML format in which labels and distributors deliver releases and their metadata to streaming services and stores.
Purpose
Labels, distributors, streaming services, collecting societies and publishers all exchange the same kinds of information — what a release contains, who made it, where it may be sold, and how much it was used. DDEX standardizes those messages so each company implements one format rather than a different one for every partner.[1]
Principal standards
- ERN — Electronic Release Notification. Describes a release, its tracks with their ISRCs, contributors, artwork, territories, deal terms and dates, and delivers it to a store.
- DSR — Digital Sales Reporting. The format in which services report usage and revenue back up the chain, the raw material of every royalty statement.
- RIN — Recording Information Notification. Captures studio-session data — who played, sang, produced and engineered — at the point of creation.
- MEAD — Media Enrichment and Description. Carries descriptive data such as moods, lyrics and focus tracks for discovery.
Messages are expressed in XML, and identify parties and works by standard identifiers such as ISRC, ISWC and ISNI.[1]
In practice
Most artists never see a DDEX message: their distributor produces the ERN from the form they fill in, and receives DSR reports in return. Problems at that step — a missing contributor role, a mistyped ISRC, the wrong release date — propagate to every store the release is sent to.
Questions
What is a DDEX ERN?
An Electronic Release Notification: the XML message a label or distributor sends to a store to deliver a release, its tracks, metadata, artwork and commercial terms.
Do I need to understand DDEX to release music?
Not usually. Distributors generate DDEX messages on the artist's behalf. It matters to anyone building or auditing a supply chain.
