Managing research data during and after a project is essential. In the course, you will learn how to write a Data Management Plan (DMP), which includes the basic rules and good practices of Research Data Management (RDM) – a document that explains what you will do with your research data at each stage of your project – how the data will be described, analysed, stored, and what tools will be used to share and archive them after the project ends. With this guide, we want to contribute to professionalism in data management and increase the value of research data.
