It revolves around the ownership of data. ‘There is a new deal on data,’ says Francesca Bria, the woman charged with turning Barcelona into a truly smart city — a city that harnesses the power of technology and puts it to use solving the problems of its citizens. ‘We believe that data is a public infrastructure — like water, like roads, like the air we breathe — and it should be treated as such. It belongs to the citizens of Barcelona.’
