Data providers are offered various licensing models for defining rights of use for research data. Licenses are standard contracts that allow certain actions (e.g. reading, copying, redistributing, modifying, combining with other data) for a licensed object. RADAR recommends the use of liberal and widespread licenses, as they facilitate reuse of research data. RADAR recommends Creative Commons licenses due to their wide distribution. They are also suitable for research data. For more information on licensing of research data, please refer to our overview.
