On May 9, 2013, President Obama signed a groundbreaking new executive order that will ensure that non-confidential governmental data will be made publicly available. The executive order, Making Open and Machine Readable the New Default for Government Information, and the resulting Open Data Policy will ensure that "Government information shall be managed as an asset throughout its life cycle to promote interoperability and openness, and, wherever possible and legally permissible, to ensure that data are released to the public in ways that make the data easy to find, accessible, and usable." (Open Data Policy, section 1).
