Provide clear text, descriptions, languages and lighter alternatives as first-class resources.
Who this is for: Public services, schools, publishers and accessibility teams. Illustrative concept, not a deployed OSYNIA capability.
A rich-media information page can be difficult to use with slow connections, assistive technology or older devices.
A rich-media information page can be difficult to use with slow connections, assistive technology or older devices.
Relevant contracts: OSYNIA-E experience and accessibility contract plus OSYNIA-R resource representations.
“Show the key steps from this training page as clear text that works with my screen reader and limited data.”
Switch between General and Technical in the header to explore the same journey at two levels.
Creators provide text instructions, image descriptions and captions when publishing their material.
Link accessible representations and language variants to canonical resource identities with editorial provenance.
Text guide, captions and diagram description available
The browser or service learns which versions are available.
Resolve representation metadata for language, modality, size and accessibility semantics.
Available: plain text, captioned video, diagram description
The visitor selects simple text and the language they understand best.
Negotiate language and representation without requiring inference or a paid AI service.
Low-data text representation selected
The page displays meaningful headings, steps and descriptions compatible with assistive technology.
Serve semantic headings, structured text, correct reading order and accessibility-tested controls.
Readable steps without mandatory video download
People using different devices and assistive technology test whether the information is actually usable.
Validate WCAG-related behaviour, keyboard navigation, screen-reader tasks and constrained-network performance.
Accessibility test results, including failures, recorded
“Here is the text guide, with headings and step-by-step instructions. The full video is optional.”
Example completion: essential training steps are accessible on a lower-bandwidth connection; usability remains subject to testing.
A proposed success message must be backed by actual execution and verification in a real implementation.
This example depends on information that explains what it is, trusted links to other information, and clearly described operations when an action is needed.
What must be in place:
{
"resourceId": "training:42",
"representations": [
{
"type": "text/html",
"language": "en",
"lowBandwidth": true
},
{

"language": "en"
},

"type": "video/mp4",
"optional": true
}
],
"requiresAi": false
