OIMAP is committed to making its site accessible to persons with disabilities. The targeted level is level AA of the Web Content Accessibility Guidelines (WCAG 2.1) and of the RGAA framework, on an indicative basis.

This page describes the measures taken, the known limitations and how to report an obstacle. It complements the site map and the legal notices.

Indicative breakdown of efforts across the four principles.

The commitments

The Organisation builds accessibility into page design: consistent heading structure, sufficient contrast, adjustable text sizes, labelled forms. Every new piece of content is checked before it goes online.

Regular audits, carried out by specialists and by the users concerned, complement automated checks, which detect only some of the difficulties.

Keyboard navigation and screen readers

All functions of the site can be used with a keyboard. A skip link, placed at the start of the page, allows you to go directly to the content. The tab order follows the logical reading order and the focus is always visible.

Pages are structured with landmarks and hierarchical headings to make reading easier with a screen reader. Tables have headers and a description.

Colours, text and images

Colour is never the only means of conveying information. The contrast of body text reaches at least 4.5 to 1, and dark mode respects the same thresholds. Text can be enlarged up to 200% without loss of content.

Informative images have a text alternative; decorative images are ignored by assistive technologies. Charts are accompanied by an equivalent data table.

Known limitations

Some older documents, scanned before 2015, may not be fully tagged. They are being gradually replaced. Some mapping modules have list alternatives, but their use remains less comfortable.

Content supplied by third parties, such as partners' videos, is not always subtitled. Where this is the case, a transcript is provided on request.
