In the context of open science the goal of the European Commission is that the research data from Horizon 2020 projects are deposited as open data in a digital repository. From the Horizon 2020 program in 2017, the Open Research Data Pilot will be extended to all fields. This means that creating a Data Management Plan is required as part of the pilot. Opting out remains possible.
