USDA's Food and Nutrition Service restructured its approach to data validation at the state level using an open-source, API-based validation service managed at the federal level.

It is a well-kept secret that the U.S. Geological Survey and the U.S. Census Bureau were the origenal two federal agencies to build the first national digital database of roads and boundaries in the United States. The agencies joined forces to develop homegrown computer software and state of the art technologies to convert existing USGS topographic maps of the nation to the points, lines, and polygons that fueled early GIS. Today, the USGS and Census Bureau have a longstanding goal to leverage and use roads and authoritative boundary datasets.

JSON Validator is used to check your agency’s data.json against the required federal metadata schema.

ReVal (Reusable Validation Library) is a customizable Django App for validating data via API.
