The United State's Federal Government's Open Data Portal

Data.gov, the federal government’s open data site, aims to make government more open and accountable, increase citizen participation in government, create opportunities for economic development, and inform decision making in both the private and public sectors. Data.gov implements Title II of the Foundations for Evidence-Based Policymaking Act of 2018 Public Law 115-435. The OPEN Government Data Act makes Data.gov a requirement in statute, rather than a policy. It requires federal agencies to publish their information online as open data, using standardized, machine-readable data formats, with their metadata included in the Data.gov catalog. Data.gov is working with an expanded group of federal agencies to include their datasets in Data.gov as they implement the new law. In addition, the law requires that GSA work with the Office of Management and Budget and the Office of Government Information Services to establish an “online repository of tools, best practices, and schema standards to facilitate the adoption of open data practices across the Federal Government.” Data.gov was built with open source software. Anyone, especially local, state, and foreign governments are welcome to borrow the code behind Data.gov.
