For programmes commissioned from 15 August 2016 (and by arrangement some programmes before that date), Producers will input perceived data about individuals appearing in the programmes into Diamond at the delivery stage as well as encouraging those in front of and behind the camera to participate in the gathering of actual data by allowing their emails to be input so that they can be contacted by the Diamond system. In order to achieve this in accordance with the law, Pact and the broadcasters have taken advice on what wording must be included in release forms; contributor agreements; staff contracts; and all other agreements for those either appearing in or making a programme.
