This deliverable consists of the second interim data management plan for the IMPETUS project. It builds on the first interim version of the DMP delivered in M12 of the project, which itself builds on the preliminary DMP delivered in M6. It outlines the data the project has already collected, produced, sourced or otherwise used, as well as any collection, production, sourcing and use that may be foreseen. This data management plan will continue to be updated throughout the project and a final iteration will be submitted at M48.
