data.mil: An Experiment in Defense Open Data

The U.S. Department of Defense is opening up "vast troves of data" in the hope that sharing military data with the public will generate opportunities for improving efficiency, crowdsourcing problem solving, and improving the public's understanding of the U.S. military. The website and datasets are described as an "experiment" in testing various ways of sharing defense-related data. The public is encouraged to analyze the data and share their feedback.
