Open Data: Additional Action Required for Full Public Access, Report to Congressional Committees [open pdf - 4MB]
From the Highlights: "Federal agencies create and collect large amounts of data to fulfill their missions. Public access to open data-- data that are free to use, modify, and share--holds great promise for promoting government transparency and engendering public trust. The OPEN [Open, Public, Electronic and Necessary Government Data Act of 2018] Government Data Act includes provisions for GAO [Government Accountability Office] to report on federal agencies' comprehensive data inventories and on the value of the data made available to the public, among other requirements. This report examines, among other things, (1) the extent to which OMB [Office of Management and Budget] met its statutory requirements; (2) selected agencies' progress developing comprehensive data inventories; (3) the extent to which selected agencies engage with the public; and (4) how data users value and use information made publicly available. GAO reviewed four selected agencies' websites and related documentation, and interviewed OMB staff, General Services Administration and agency officials, and data users."
