The order requires government agencies to create internal indexes of their data, make public lists of their public data and list all the data that can be made public, Miller noted.
"Open data is more than bytes, 1s and 0s and lines of code," Miller said. "It's not just a set of information that fuels data portals or app contests. Open data empowers Americans to know how government functions, gives them the means to get engaged and enables them to oversee the special interests."
As part of the executive order, the administration will launch services to improve data visualization and mapping tools at Data.gov. the central repository of U.S. government data. Administration officials are also releasing new open-source tools on Github, a collaborative development site.
