The XML Testbed tools were produced by the National Institute of Standards and Technology (NIST), an agency of the U.S. government and by statute are not subject to copyright in the United States . Recipients of these tools assume all responsibility associated with their operation, modification, maintenance, and subsequent redistribution.
The NIST XML Schema development and testing process is documented as the Model Development Life Cycle, which is an activity model for the creation, use, and maintenance of shared semantic models, and has been used to frame our research and development tools. We have worked with a number of industries on refining and automating the specification process and provide a wealth of information on how to use XML to address your integration needs.
