The technical group of works together to develop a common list of standards and technical specifications to achieve interoperability of data, systems, and platforms among cities and communities and suppliers around the world to enable solutions such open urban platforms and digital twins.

These standards are called 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. A version adapted to the European context and legislation - the MIMs Plus - is being developed in parallel by the Living-in.EU technical commitment and sub-group.

Based on the experience of working on the MIMs over the last few years, the Living-in.EU technical sub-group is in the process of reviewing the MIMs Plus 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 (version 5) are still valid, with the MIMs in the new format (version 6) provided as alternative versions.

For information on the MIMs Plus version 5, see below.

The latest version of the MIMs Plus (version 6) can be downloaded here or on the link to the right.

Technical subgroup - Work plan Priorities 2023:

  • Continue the development of MIMs Plus 

  • Develop operational guidance related to technical aspects of procurement, to deployment/integration and to the development of methodologies for conformance and compliance testing 

  • Explore the interconnection among platforms, to establish a European Smart communities data space and linking with other data spaces
