A new standard for real-world accessibility data.

A11yJSON is a GeoJSON-compatible data format to specify real-world accessibility. With more than 150 criteria, it covers tangible products, physical places, elevators and escalators, services, or events.

You should use it to make your data accessible – and allow its exchange with accessibility-related apps.

Together with Framefield, I co-created the open spec for Sozialhelden – it’s the data format for accessibility.cloud and Wheelmap.org.
