The Data Management Plan of the TURNkey project aims to aid the TURNkey consortium to meet their responsibilities regarding research data quality, sharing and security in accordance with the Horizon2020 Guidelines on Open Access. It describes the data management life cycle for the data to be collected, processed and/or generated by TURNkey. As part of making research data Findable, Accessible, Interoperable and Re-usable (FAIR), it also includes information on: • the handling of research data during and after the end of the project; • what data will be collected, processed and/or generated; • which methodology and standards will be applied; • whether data will be shared/made open access; and • how data will be curated and preserved (including after the end of the project).
