Authoring Tool Accessibility Guidelines (ATAG) 2.0
Authoring tools are software and services used by web developers, designers, and writers to create web content such as static pages and dynamic applications. The Authoring Tool Accessibility Guidelines (ATAG) explain how to make these authoring tools themselves accessible so people with disability can create web content, and how to help authors create more accessible content that conforms to Web Content Accessibility Guidelines (WCAG). ATAG is part of a series of accessibility guidelines alongside WCAG and User Agent Accessibility Guidelines (UAAG), with their relationships explained in Essential Components of Web Accessibility. Published in 2015 and referencing WCAG 2.0, ATAG remains relevant today as it is technology agnostic, though users are encouraged to use the latest version of WCAG 2.
