Talk given at Fronteers 2015 in Amsterdam. In a world where many of our digital spaces are becoming more closed than ever, open data is a concept that is rapidly on the rise. In this talk we'll explore what open data is (and what it isn't), and why we should care about it. We'll look at how you can introduce it into your projects with regards to practical publication and consumption, and discuss some useful tools and reference points. Open data isn't just dry and technical - it gives us great scope to be creative, and throughout this talk we'll go through some of the amazing things that it has been used for globally in the hope that it will inspire you to create something amazing yourself.
