What’s in the name
Ommisa is an acronym: OIML Machine Intelligence System Assistant — an assistant over the OIML corpus, powered by machine intelligence. Read in French, the same letters read the other way round: « Assistant Système d’Intelligence Machine de l’OIML » — the assistant of the OIML’s machine-intelligence system. One name, both working languages of the programme.
The service exists because legal-metrology knowledge deserves better than an assistant that answers from memory. Every substantive answer here cites the exact publication, edition and clause it rests on; normative values are quoted verbatim from the producer’s own payload; and when the corpus does not contain an answer, the system says so instead of guessing.
What it does
- Grounded answers over the OIML corpus — Recommendations, Basic publications, Guides, Documents and Expert reports — with clause-level citations and measured confidence.
- The certificate register, queried live: counts, latest issues, per-holder and per-country breakdowns, with document links.
- Typed tables, formulas and figures rendered from the producer’s own payloads — never re-typed by a language model.
- Conformance by execution: machine-checkable requirements are evaluated against the values you state, with the arithmetic shown.
- An agent loop: for data questions the assistant composes and runs its own queries over the published tables, correcting itself from the results.
