The White House has released "Two Years of Transformative Open Data for Public Good."
Here's an excerpt:
Two years ago, President Obama signed an Executive Order (E.O.) to improve how our government shares information for the benefit of the American people. The E.O. meant that for the first time in history, Federal government data was required to be open by default with common standards and machine-readable formats. As a result, government information is now more easily discoverable with the necessary safeguards to prevent release of sensitive and personally identifiable information. . . .
Today, more than 130,000 datasets reside on data.gov, the repository for the U.S. Government's open data. Data.gov is updated daily with datasets on important issues such as Climate, Public Safety, Health, and Education. Users can find data on the consumer complaints filed against their banks, on-time performance of airlines, or health indicators in their communities such as the prevalence of heart disease or cancer. One reason this is so important is that open data allows businesses, software developers, and anyone else who's interested to create consumer-friendly applications to help us all make better-informed decisions about health care, transportation, energy use, and more. Open data also has other positive impacts, such as fueling creation of new businesses and jobs. And the best part is that we're just getting started.
