Balisage Paper: NIEM: Implementation experience
The U.S. National Information Exchange Model (NIEM) is a 6000-element XML vocabulary used by U.S. government entities and their information-sharing partners at the federal, state and local levels. While adoption of NIEM is growing, there is a lot of variation in how it is being managed. Using NIEM, like using any large complex XML model, presents challenges including approaches to customization, interoperability among differing subsets, and versioning. A variety of approaches to implementing NIEM and integrating it into existing organizational infrastructure are discussed and compared.
