FAIR data is not only becoming a requirement set by European and national funding agencies, but by making your data FAIR, you are making it easier for others to find, use, and cite your data. In this course you will learn how to make your data Findable to a wide audience, how to make them Accessible to people and to machines, and how to make them Interoperable so they can be Reused by others. After learning the principles, you will practice your knowledge in quizzes and practical sessions. This is a 3-day course for onsite participants, of which the first 2.5-days are also open to online participants. In the final half day, the onsite students will bring all they have learned together in an interactive Make-My-Data-FAIR session. We will also have a "Data Clinic" in which the onsite students can ask their particular questions of the various experts of the VLIZ Data Centre on data FAIRness, data management, data archiving, etc.
