• There is not already opt-out mode and closing the data needs to be explained ("as open as possible, as closed as necessary„)
• Principles FAIR a DMP during reporting (regularly update)
• European Open Science Cloud (EOSC) – for some calls
  
• CC0/CC-BY
• Each article must have available validation data that is discussed in the publication, unless an exception applies
