How do you design an XML information exchange between US government entities?

The National Information Exchange Model (NIEM) is rapidly becoming the most important XML exchange standard for the U.S. government and its information partners. This article by Priscilla Walmsley, a four-part series, provides an overview of the process for defining a NIEM information exchange. It then takes one through the first step—modeling an exchange using UML, through the last step - assembling the schemas, documentation, and all the other artifacts of an exchange into a complete NIEM-conformant IEPD. The last article in these series, also describes the process of validating and publishing an IEPD.
