Data are a central resource of the 21st century. Data serve individual, collective, and common good functions. Data and data ecosystems shape the competitiveness of commercial and non-commercial as well as public actors alike. Calibrating the use and use cases for data is a vital question (self-)regulators face — on the national, supranational, and international level. Global, comparative, and interdisciplinary perspectives are required to strike adequate balances between data co-operation and data competition. These perspectives go far beyond data protection law and include inter alia data economy law, open data law, trade secret law, and IP law. Against this background, this series tackles central questions of global and comparative data law & policy and provides in-depth studies and monographs as well as corresponding conference proceedings.
