„The days of keeping our research results to ourselves are over. There is far more to gain from sharing data and letting others access and analyse that data.“EU-Commissioner Carlos Moedas, Lund 4.12.2015
Open data is data that can be used, changed and passed on by anyone and for any purpose.
The Open Knowledge Foundation explains Open Data in the Video.
If the video is no longer available, look for alternatives.
Tim Berners-Lee called for "raw data now" at TED 2009 to encourage governments, academics and institutions to make their data freely available on the web. A year later, at TED University 2010, he showed some interesting results when data are networked.
