The present document is the Deliverable 6.1 Data Management Plan within WP6 Project Management of the MemCat project. The main objective of D6.1 is to provide the plan for managing the data generated, collected, and transferred during the project. Likewise, this document will include the necessary information on how the data will be preserved and handled as well as the methodologies used to accomplish the tasks. This first Data Management Plan (DMP) shows that there are mainly 12 data sources that will be produced as part of the project activities and that are relevant to be included in the DMP. Following the EU’s guidelines regarding the DMP, this is a living document and hence several issues will be updated during the project lifetime: in months 30 (31/10/2026) and 48 (30/04/28).
