The past year I've been speaking about open data at a bunch of different conferences, and I'm even organizing the Oslo Open Data Meetup, but what is this open data really all about?
A common answer is that data paid for by public money should also be openly available to the public that paid for it, but how do we define and ensure such loose terms as open and available? One way to do this is by publishing your data using open licenses, meaning licenses that adhere to the Open Knowledge Definition. This definition is available in a bunch of languages, including a Norwegian version which I helped translate. For practical use they also provide reviews of conformant licenses, including several of the well known Creative Commons and Open Data Commons licenses.
And for those that are interested in the processes behind this work, please join in at the 5th Open Knowledge Conference taking place in London this April 24th. Maybe I'll see you there :-)
