This Data Management Plan (DMP) outlines the sources and procedures for data collection/generation and processing as well as organization, storing and sharing during the LuxHyVal project life cycle (the duration of the project and any additional data storing/accessing time after the project is ended). More specifically, the DMP provides information on the choice for data to be made openly accessible or to have a restricted access (consortium only, private), access to project related publications, summary of the expected datasets, implementation of FAIR data principles, data security, handling of the personal data, and ethical principles applied.
