As specified in its Charter, the mission of the NBAC is to set the business architecture​ and requirements of NIEM, manage NIEM Core, and facilitate the processes for the regulation and support of NIEM domains. The NBAC focuses on the following areas:

  • Business Architecture: The NBAC oversees and validates the construction, maintenance, and use of the business architecture framework for NIEM.
  • NIEM Core: The NBAC provides management and oversight of the NIEM Core—the central part of the NIEM data model that’s commonly understood across all domains.
  • Community: The NBAC serves as the forum for the admission of new domains and interactions between domains, and coordinates action to maintain the NIEM community.

Roles and responsibilities

The committee’s responsibilities are to:

  • Maintain the integrity, usability, and maturity of NIEM core, and engage in any requisite harmonization and issue resolution activities.

NIEM’s domains—communities that are formally established to manage and govern a portion of the NIEM data model—serve as the foundations of the committee. The NBAC is led by co-chairs and includes voting members, a NIEM PMO liaison, and observers and invited participants.
