NIEM Version 4.1 is Now Available

​NIEM version 4.1 and its associated products are now available for download and use. Products include NIEM XML schemas (XSD), a spreadsheet (MS Excel) of all data components in the model, and alternate database formats (MS Excel, MS Access, and CSV). This release is the latest version of the NIEM common vocabulary that enables efficient information exchange across diverse public and private organizations.

NIEM 4.1 is a minor release that incorporates content identified since NIEM 4.0 was released in July 2017. The NIEM Program Management Office, NIEM Business Architecture Committee, and the NIEM Technical Architecture Committee collaborated and worked closely with community subject matter experts to develop, review, and enhance reusable content in the model for this release.

Highlights of NIEM 4.1 include:

• Domain content updates from Biometrics, Emergency Management, Human Services, Justice, and Military Operations.
• Core Supplement 4.0.1 that addressed the following technical issues tracked via NIEM Releases GitHub issue tracker:
  • Create a polygon node element of type nc:LocationType (issue #9)
  • nc:LocationHeightMeasureType should extend nc:LengthMeasureType instead of nc:MeasureType (issue #13)

The NIEM release cycle allows us to make NIEM model updates on a predictable and sustainable schedule that best meets users’ evolving needs. As those needs evolve, NIEM allows for flexibility and growth. The changes involved in NIEM 4.1 will continue to advance information exchange across all levels of government and various organizations.

Updated versions of the NIEM Schema Subset Generation Tool , Movement, and the Wantlist Migration tools are now available for use. Visit NIEM’s Tools Catalog to learn more about tools available to support various NIEM-specific capabilities.
