This is an official ODERSA website. Here’s how you know

The official domain

The address of this site ends in odersa.org. Every service the association runs sits on a subdomain of odersa.org and nowhere else. If the address in your browser’s address bar does not end in odersa.org, this site is not ours.

Free, and no account

Everything is open straight away. No sign-up, no account, no password, no subscription, no advertising. Nothing is held back for those who pay, because there is nothing to pay for.

No data collected

This site does not follow you: no tracker, no tracking cookie, no measurement tool built into these pages, and nothing measured on your device. Our host counts requests in aggregate, as any server that answers does: a total, never a profile. You do not have to take our word for it: open your browser’s developer tools, go to the Network tab, and reload the page. You will see the full list of what the site asks for. Everything comes from odersa.org, nothing goes anywhere else.

Free to reuse

The content is published under the CC BY 4.0 licence. You may copy it, translate it, print it and pass it on, for your classes as much as for the people around you, on one condition only: credit ODERSA.

News

The division’s dated record

Site releases, measurement campaigns, publications: each entry stays short, dated, and points to the page that is authoritative. This page grows only with the facts.

2026

· Notes

The first research note is published

Note 2026-01, “A verifier that knows how to fail”, reads the measurement campaign of 28 August 2026: why a check that finds nothing proves nothing by itself, and what the instrument’s calibration – in both directions – makes readable. It introduces no new figure.

The authoritative page: Note 2026-01.

· Data

The site’s open data is documented

The active project’s indicator file, served at data/impact.json, is now documented field by field: what each value measures, its reading date, and the contract that governs the dictionary.

The authoritative page: Data.

· Measurements

The extended measurement campaign is published

Thirty subjects, chosen in lexicographic order, re-read across the 1,000 languages: 1,646 values compared across languages, no conflict. The verifier’s calibration is measured in both directions – 105 artificial corruptions detected out of 105, no false alarm on 113 untouched texts. All 197 subjects of the country domain are served in the four witness languages, and 25 writing systems are detected in the outputs.

The authoritative page: Results and Measurements, figures and threats to validity included.

· The site

The division’s website is live

ODERSA Research publishes its website: the mission, the four-axis research program, the measured results, the validation approach and unretouched multilingual demonstrations.

The affiliation can be checked against the official information about the association.

The rule of the record

An entry is a fact, never a promise

Every entry carries its date and points to a page that proves it. Nothing is announced here before it exists, and nothing is celebrated here: anniversaries, round milestones and teasers have no authoritative page.

Follow without an account

The Atom feed of this news is served at feed.xml: any aggregator reads it, with no sign-up, no account, and without the site knowing who follows it. It is the only form of subscription this site offers, and that is a choice: following should not cost an address.
