The MIMs Specification v9.0 is now in its open review phase.

OASC members and partners are invited to review the updated specification, contribute feedback and propose amendments. The draft is available at mims.oascities.org.

The open review phase will run until 31 May 2026.

Formal amendment proposals must be submitted through the relevant MIM Working Groups, where all contributions will be coordinated and processed. For general questions regarding the review process, please contact Thimo Thoeye (thimo[at]oascities.org).

This review phase is an important step in ensuring the continued relevance, quality and collaborative development of the MIMs framework. We encourage all eligible stakeholders to participate.
