Data Inventories and Policy Landscape (original) (raw)

This report presents a summary of existing experimental data holdings together with current access policies in European experiments. It also presents an assessment of their compliance with FAIR Principles and makes suggestions for how to improve the present practices/policies towards a more FAIR and more Open Data management. All European tokamak and stellarator experiments grant access to their measured and processed data on an individual basis, to collaborators who are formally identified as members of the experiment's team. Once a researcher is authorized for a given experiment, he has access to all measured data and processed data (Plasma Reconstruction Chain, PRC) of that experiment. Data has some degree of FAIRness at the level of a given experiment, but EU experiments are presently not interoperable, which prevents from exploiting results of the EU fusion experiments at their full potential. In particular, Data Mining / Machine Learning activities cannot be conducted acro...
