NIEM 3.0 Release

NIEM 3.0 is a major release, published October 2013.



  • NIEM adopted a new annual release strategy with a 3-year cycle: a major release one year would be followed by minor releases the next two years.

  • Added the Biometrics (biom) domain - replaced the ANSI NIST namespace from NIEM 2.0

  • The Family Services (fs) domain was renamed as Children, Youth, and Family Services (cyfs)

  • Military Operations (mo) debuted as a domain update after the NIEM 3.0 release

  • Augmentations were revised to use element substitution instead of type extension.
    • This addressed challenges users had faced with the limits of type extension, which only allowed for the use of an augmentation for a type from a single domain.
    • Element substitution allows for IEPD developers to use multiple domain augmentations to be used in combination together.
  • Extensive review and harmonization of Core components

  • Simplified XML schema syntax of elements and types

  • Added the conformanceTargets attribute to NIEM schemas to allow users to explicitly designate which NIEM specifications and rule sets are applicable

  • Added support for local terminology, allowing namespaces to define subject area-specific terms that do not appear in standard dictionaries

See the NIEM 3.0 change log spreadsheet for changes.
