DDEX messages allow categorising Resoucres in several ways:


The following types exists for sound recordings

  • MusicalWorkReadalongSoundRecording
  • MusicalWorkSoundRecording
  • NonMusicalWorkReadalongSoundRecording
  • NonMusicalWorkSoundRecording
  • NonMusicalWorkSoundRecordingSpokenWordSoundRecording
  • Unknown
  • UserDefined

Other resource types have other lists.

Some companies use the information to automatically process data received. A Works licensor may, for instance automatically levy a royalty on all sound recordings being classified as being based on a MusicalWork. It is therefore essential for all message senders to ensure that correct resource types are provided.


(*) MIDIs are no longer available in ERN-4. Please use sound recordings instead.
