The DiAGRAM (Digital Archiving Graphical Risk Assessment Model) decision support system was initially developed from early 2020 by the University of Warwick Applied Statistics & Risk Unit (AS&RU) as part of the National Lottery Heritage Fund supported project Safeguarding the Nation’s Digital Memory. AS&RU’s work was also supported from an Engineering and Physical Sciences Research Council Impact Acceleration Account. The National Archives contracted Jumping Rivers to undertake additional development work from August to October 2020, maintaining the terms of the licence below.

For more details about the project see the main project webpage on The National Archives’ website.
