There are two ways to communicate 'take-downs', i.e. the request from a Release Creator to a DSP to stop trading a Release:

  • Sending a NewReleaseMessage without a Deal; or

  • Sending a PurgeReleaseMessage.

While the two messages were designed for different purposes (one to allow a DSP to make Releases available and to communicate changes in availability – and the other to take down Releases that have been corrupted over time), both can be used to instruct a DSP to not make available a specific Release any longer.
