Data Exchange Description
The Concentrated Animal Feeding Operation (CAFO) exchange makes state environmental data associated with CAFOs available on the Exchange Network. Under the Southeast CAFO Environmental Information Exchange pilot project, the U.S. Environmental Protection Agency (EPA) committed to develop a set of schemas and a node client that allows users to query multiple state nodes at once returning an aggregated result set. Mississippi, North Carolina, and South Carolina mapped the CAFO schema to their databases that house CAFO information and developed web services that EPA Region 4 and Partner states can access via the EPA-developed client tool.
Since the first version of the CAFO flow was primarily a pilot to demonstrate the ability of the Exchange Network to implement distributed queries, the complexity of the flow has been intentionally limited – with a small number of data services and no linkages with EPA transactional systems. This minimizes the resources required on the part of Partners to stand up the CAFO services and leaves the door open for future enhancements to the flow.
Currently the CAFO data flow defines only three Data Services – all Query requests. In the future, Partners may consider supporting a Solicit version of these requests, or other services.
The CAFO schema and supporting documentation have been approved for use on the Exchange Network. Implementation resources for the most current version follow.
