+On January 14, 2019, the <a href="https://www.congress.gov/bill/115th-congress/house-bill/4174/text">Foundations for Evidence-Based for Policymaking Act</a> ("Evidence Act"), which includes the OPEN Government Data Act, was signed into law. The Evidence Act requires the Office of Management and Budget, the Office of Government Information Services, and the General Services Administration to develop and maintain an online repository of tools, best practices, and schema standards to facilitate the adoption of open data practices across the Federal Government. When the new repository is launched, it will replace and retire Project Open Data. Check back here for updates.
