Last week we discussed how the current era of the Web is evolving. One of the concepts we noted was Linked Data, an idea whose time has come in 2009. Sir Tim Berners-Lee, the inventor of the Web, gave a must-view talk at the TED Conference earlier this year, evangelizing Linked Data. He said that Linked Data was a sea change akin to the invention of the WWW itself. We've gone from a Web of documents, via the WWW, to a Web of data. Berners-Lee is now on a crusade for everyone from government departments, to individuals, to open up their data and put it on the Web - so that others can link to it and use it. In this post we give a high-level overview of Linked Data. Read on to stop and smell the roses. A great place to start to understand Linked Data is Sir Tim's TED talk, embedded below. It's just over 15 minutes and highly recommended if you want to grok where the Web is headed. The slides are also available.
