Everyday our cities generate increasingly vast amounts of data. What happens when this data from across public, private and the third sector becomes open? Mark Barrett argues that focussing our use of local data so that it is “for the city, by the city†is the path towards unlocking the most value from open data.

Mark Barrett is an open data lead for Leeds, and created Leeds Data Mill – the open data platform for the city – surfacing public, private and 3rd sector information. He also co-founded and co-run Leeds Data Thing – a group set up to explore the benefits of open data across industries within the city.
