The MaRDI-Gross project aims to provide high-level guidance for the strategic and engineering development of Data Management and Preservation plans for Big Science data. The main outcome will be a document, the nominal audience for which is therefore rather narrow. However, the intention is that the document be of use to other planners and data architects who wish to implement good practice in this area.

The goal of the document is not to provide mechanically applicable recipes, but to allow the user to develop and lead a high-level plan which is appropriate to their organisation. Throughout, the document is informed where appropriate by the OAIS reference model, which generally provides a useful guide to HEP data management planning.
