Minimal Interoperability Mechanisms – MIMs

The mission of Open & Agile Smart Cities (OASC) is to unite cities and communities around the world to build a global market for solutions, services, and data based on the needs of cities and communities.

To achieve this mission, OASC champions the Minimal Interoperability Mechanisms (MIMs), a set of practical capabilities based on open technical specifications that allow cities and communities to replicate and scale solutions globally. The MIMs are developed by the OASC Technology Council and governed by the Council of Cities and the Board of Directors.

MIMs provide the technical foundation for procurement and deployment of urban data platforms and end-to-end solutions in cities & communities worldwide.

Based on the experience of working on the MIMs over the last few years, OASC is in the process of reviewing the MIMs to provide them with a consistent structure and greater clarity.

As part of this, work has been started on re-drafting MIMs 1, 2, 4 & 7 in the new format.

Because the content of the MIMs in the new format is still being further consulted on and developed, the MIMs in the 2022 format are still valid, with the MIMs in the new format provided as alternative versions.
