This chart is based on a crowd-sourced open Google Spreadsheet that consolidates guidelines from federal agencies as a result of the Whitehouse’s Office of Science and Technology Policy’s (OSTP) 2013 statement. The chart is an overview of each agency’s compliance with policies that are intended to “[open] goverment data resources” by working towards public access for all research outputs supported by federal funding (Process Toward Opening Data Government Resources. The White House, 16 Aug. 2013. Web.).
