Project Governing Board


The PGB must at all times have a chair or two co-chairs. The PGB chair or co-chairs are confirmed annually by the PGB itself via a call for nominations, and if required, a full majority vote of the PGB.


For most decisions, the PGB operates by lazy consensus. In addition to the votes required by OASIS Open Project Rules, decisions on the following items require a full majority vote of the PGB:

  • Any action or decision that may bind the NIEMOpen project to commitments or obligations with any external party or entity, including but not limited to legal, financial, or intellectual property related commitments or obligations
  • Promoting work to an OASIS standards track
  • Starting or consuming a new project into the OCA
  • Endorsements, partnerships, or liaisons with other groups
  • Substantive changes to the Governance policies or documents
  • The TSC recall procedure

Technical Steering Committees

  • Governance of the NIEM Business Architecture Committee TSC can be found at GOVERNANCE-NBAC.
  • Governance of the NIEM Technical Architecture Committee TSC can be found at GOVERNANCE-NTAC.

Recall Procedure

Any community member may submit a request for recall of a TSC chair to the PGB at any time by submitting the request and sufficient justification to the PGB chair or co-chairs. Such requests shall be held in confidence by the PGB chair or co-chairs. In the event of receipt of such a request, the chair or co-chairs shall schedule the recall as an item for discussion at the next PGB meeting, which shall be held no later than 30 days after the receipt of the request. After subsequent discussion, the recall shall be decided upon by a full majority vote of the PGB. In the event of a recall vote passing, the TSC chair shall at that time be considered immediately recalled and be relieved of all responsibilities conferred via the position.

Incubation Process

At this time, new projects may be accepted into NIEMOpen at the sole discretion of the PGB.

Updating Governance

All substantive changes in Governance require a full majority vote of the PGB.

CLA & Non-assert signatures required

All technical contributions must be covered by a Contributor's License Agreement. This requirement allows our work to advance through OASIS standards development stages and potentially be submitted to de jure organizations such as ISO. You will get a prompt to sign this document when you submit your first pull request to a project repository, or you can sign here. If you are contributing on behalf of your employer, you must also sign the ECLA here.
