Semantic primitives
Meaning must survive when the visual form disappears.
These examples are source contracts for public learning content. They do not claim that every historical page has completed manual assistive-technology review.
The record
What this policy is, and what it covers.
Owner: ATRIYA SYSTEMS PVT LTD. Effective version 1.0 of record web5-pr20-inclusive-serving-v1. This record carries a version and not a date; an effective date has not been set for it.
Clauses
What published content must do.
Each clause is held by the record above, not by this page.
- Every equation is published as MathML, not as a picture of an equation.
- Every equation also carries a spoken text equivalent.
- Every diagram carries a caption.
- Every diagram carries a long description that conveys what the picture shows.
- Every data table carries a caption.
- Every data table's headers are scoped, so a screen reader can announce the row and column of a cell.
Not covered
What this policy does not claim.
These are refusals, not omissions. Each is listed in the record so it cannot quietly reappear as a claim somewhere on the site.
- That the site conforms to WCAG. No audit has been done, so no conformance is claimed.
- That it works on every device.
- That anything works completely offline.
- That a check here can diagnose your access needs.
- That installing the app is guaranteed to succeed.
- That any network speed is guaranteed.
- That every screen reader is supported. Support is claimed only where it has been proven.
- That every keyboard path is supported, on the same terms.
- That every width renders perfectly without a measured board for it.
- That your device may be fingerprinted. It is not.
- That anything is shared in the background. Sharing needs your action.
- That a private route may be published as a QR code.
Math
Readable equation structure.
The visible form uses MathML while the wrapper carries a concise spoken label.
Kinetic energy is Formula: one half m v squared..
Diagram
A visual with an equivalent explanation.
Colour and position support the concept; the caption and long description carry the meaning.
Data table
Headers remain navigable.
The scroll container is keyboard-focusable on narrow screens and does not convert table data into visual-only cards.
