W3C announced today a Workshop on Open Data on the Web, 23-24 April 2013, in London (England). The event is hosted by Google and jointly organized with the Open data Institute and the Open Knowledge Foundation. Participants will help prioritize W3C's agenda in the area of data on the Web at a time when a number of working groups have either completed or are close to completing their charters. As well the promises of government transparency and efficiency, the claim that is made most frequently of open data is that it is the "new oil" that is driving the digital economy. At this workshop, participants will discuss their experiences of realizing this aim and identify what's needed to make it easier. W3C membership is not required to participate. The event is open to all, but limited to 80 attendees. All participants are required to submit a position paper by 3 March 2013.
