This Data Management Plan accompanies the ANR-funded project EURICA. It outlines in detail the organisation of the research infrastructure and the way the data, metadata, protocols, and research resources which are produced and/or enacted in this project are created, collected, reused, stored, selected, archived, shared, protected, and published. It reflects the practices of the François's, Leulliot's, Liu's, and Smirnov's labs, the existing conventions and norms of the respective disciplinary fields, and the current relevant regulations and legislation at the level of the Universities of Strasbourg and Paris Cité, CNRS, the French Republic, and the European Union. This is the initial, version 1, of the present DMP, which should be considered as preliminary and subject to an update 24 months after the start of the project (i.e. in December 2025).
