In progress

JSON 2026

In 2020-2021 the Technical Committee developed a JSON based version of SUTI. The Bulk Location JSON-message has been widely deployed, but the remaining parts are still not in use and have been considered a draft in progress.

In early 2026 the Technical Committee therefore reviewed the 2021 version and have revised it slightly to follow JSON best practices. A JSON Schema has also been drafted. A proposal for the 2026 version will be distributed for review by SUTI members during april, after which it will be released as part of the official standard. 

Please do not hesitate to contact the Technical Committee if you have any feedback on the JSON proposal.

Link Mapping

During 2025 the Link Mapping messages (7100 & 7101), and an accompanying Excel file for documenting a SUTI link, were released as part of the official standard.

New document structure

No other changes were made to the standard itself during 2025, but numerous improvements were made to the documentation structure, clarity of terminology and a proof reading of the ”How to use SUTI” document.

SUTI on GitHub

The SUTI standard documentation can now be found on GitHub, where current and some of the earlier versions can be downloaded.

SUTI-experten & AI based development

There is now an experimental AI based SUTI expert. Try it out at ChatGPT – SUTI-experten 2026.1 — feedback is welcomed by the Technical Committee. We are expecting to develop more powerful AI based tools to simplify the development and deployment of the SUTI standard. Stay tuned!
