In 2015, the U.S. Department of the Treasury began to test a new prototype website, known as beta.USAspending.gov, to publish federal spending data in a more accessible way. The DATA Act Information Model Schema (DAIMS) architecture forms the structure of this updated website, which includes appropriations-level data by budget function, program activity, and object class linked to the contract, grant, loan, and direct payment award data.
In March 2018, USAspending.gov was officially launched with a number of updates. These include the Federal Spending Explorer, which breaks down spending information in detail; Award Search, which includes a wide range of advanced filters to target specific datasets; and Keyword Search, which provides a broader picture of federal spending data based on any given theme. Treasury has also launched the Data Lab to test out new visualizations for data on federal spending and related issues.
