The Array of Things is a Chicago-based project that aims to make a Smart City that's also open, democratic, and collaborative. It's a concept that will see sensors positioned around the city that gather data about things like air quality and foot traffic, and make it available not just to researchers and bureaucrats, but to ordinary citizens.

Charlie Catlett explains in this interview with Nora.

These sensors are meant to produce meaningful, timely data that will make cities more efficient and responsive. Many plans for smart cities involve collaboration with private companies. The question is: who owns the data that's gathered, and what can be done with it? Teresa Scassa is a law professor at the University of Ottawa. She's concerned that when cities create smart city partnerships with private tech companies, they may lose control of the data.
