This document is a deliverable of the WORM Project, funded under the European Union’s Horizon Europe research and innovation programme under the grant agreement No 101135392. The aim of this document is to establish WORM’s data management plan (DMP). The DMP builds on the principles of FAIRness, transparency and accessibility, taking EU and different national obligations into account. The DMP identifies all data collected, processed and/or generated by the project, analyses their main generators and users, and defines how data is handled during and after the project. It details the organisation, description, storage, sharing, and publication of the research data used in this research project, and specifies the key actions for ethical and legal compliance and FAIR data production. It describes the data management life cycle according to the HEU DMP template. This deliverable (D10.1) as part of Task 10.3 is an updated version of WORM’s DMP for the second interim period of the project. It builds on a previous DMP (D9.2) that has been submitted M6 of the project and that was followed up on in all WORM general assembly meetings, incorporating the comments of an external ethics review at the end of the first interim period and other new relevant material
