In the Netherlands, a wave of experiments is being conducted with the use of data and digital technologies for solving problems in public space. These experiments give rise to a number of different questions, both in government circles and among citizens. Who owns the data that is being collected in public space? How can you, as resident or visitor in that space, take more control over data and technology? How can we as government get the most out of data and technology while at the same time protecting our social values?
