In 2010 Tim Berners-Lee returned to TED to follow up his great speech about open and linked data from 2009. At this years conference Sir Berners-Lee presented some of the results that sprouted from open data.
As usual Tims presentation is very passionate about the subject and he shares his vision of the future of the web in an understandable manner. If you haven’t already seen the videos of the presentation I recommend doing so.
The slides of the presentation are available here.
