Julia discussed the nexus between Smart City thinking and Open Data during a massively over-subscribed Open Data Day hosted by the Flemish eGovernment Authority in Brussels. Julia also Chaired a special panel on Open Data trends across Europe featuring Andrew Stott, former Director of Digital Engagement and Transparency at the UK Cabinet Office and Chris Taggert from Open Corporates. Andrew convincingly argued that it often costs governments more to charge for data instead of opening it open freely. Chris gave the audience a jolt when he described the way in which firms like Walmart now track so much data on costumers that they often know if a woman is pregnant before she does!
