Digitization is one of the ground-breaking trends of this century. It is fundamentally transforming our entire economy and our society. In particular, the datafication of business processes leads to an incredibly fast and ever increasing mass of data. Such data is the blood in the veins of the digital economy. Many existing business models, but much more importantly those future business models that will drive innovation and create economic growth depend on being able to use these data. The present volume assembles the contributions to 3rd Münster Colloquium on Trading Data in the Digital Economy: Legal Concepts and Tools. In accordance with the Colloquiums general aim, they provide for a closer analysis of the different legal concepts and tools (exclusivity rights, compulsory licences, and contractual concepts) in order to promote the discussion of several options at European level to tackle the challenges in the trade of data.
