This report describes the initial version of the data management plan (DMP) for the ACEnano collaborative research project. The current DMP covers the general aspects of the ACEnano data management approaches, based on the FAIR guidelines. More specific and clearly-defined measures will be added in parallel to the integration of methods, their data output specifications, their Standard Operating Procedures (SOPs) and specific data sources into the knowledge warehouse, which will follow the time plan enforced by the case study requirements on data availability.
