The US Senate has passed the OPEN Government Data Act.
Here's an excerpt from the announcement:
The U.S. Senate unanimously passed the Open, Public, Electronic and Necessary (OPEN) Government Data Act, legislation introduced by U.S. Senators Brian Schatz (D-Hawai'i) and Ben Sasse (R-Neb.). The bipartisan bill will require public data to be accessible at Data.gov so individuals, organizations, and other government offices can utilize it.
