As 2011 comes to an end, there are 28 international open data platforms in the open government community. By the end of 2012, code from new "Data.gov-in-a-box" may help many more countries to stand up their own platforms. A partnership between the United States and India on open government has borne fruit: progress on making the open data platform Data.gov open source.
As part of a joint effort by the United States and India to build an open government platform, the U.S. team has deposited open source code — an important benchmark in developing the Open Government Platform that will enable governments around the world to stand up their own open government data sites.
