The Access to Memory Foundation has published a Proof of Concept proposal for the development of AtoM 3 on its website at https://accesstomemoryfoundation.org/development/. The Foundation plans to launch an online survey for AtoM users and other interested individuals to describe what they would like to see in the next major iteration of AtoM (AtoM 3), and will include questions about the proposal. The proposal was written by an international group of organizations that met in the UK last year: AIM 25 (UK), Artefactual systems (Canada), Docuteam (Switzerland), Imagiz (UK), Nothing Interactive (Switzerland) and Zasuko (Switzerland). We encourage everyone to read the proposal and to respond to the survey when the Foundation makes it available.
