Authoring Tool Accessibility Guidelines (ATAG)
The Authoring Tool Accessibility Guidelines (ATAG) documents explain how to make authoring tools accessible to people with disabilities. Authoring tools are software that people use to produce Web pages and Web content. A primary focus of ATAG is defining how tools help Web developers produce Web content that conforms to Web Content Accessibility Guidelines.
ATAG is part of a series of accessibility guidelines, including the Web Content Accessibility Guidelines (WCAG WG) and the User Agent Accessibility Guidelines (UAAG). Interdependent Components of Web Accessibility explains the relationship between the different guidelines.
Who ATAG is for
ATAG is primarily for developers of authoring tools, including:
- Editing tools specifically designed to produce Web content, e.g., what-you-see-is-what-you-get (WYSIWYG) HTML and XML editors
- Tools that offer the option of saving content in a Web format, e.g., word processors or desktop publishing packages
- Tools that transform documents into Web formats, e.g., filters to transform desktop publishing formats to HTML
- Tools that produce multimedia, especially where it is intended for use on the Web, e.g., video production and editing suites, SMIL authoring packages
- Tools for site management or site publication, including content managements systems (CMS),tools that automatically generate Web sites dynamically from a database, on-the-fly conversion tools, and Web site publishing tools
- Tools for management of layout, e.g., CSS formatting tools
ATAG and supporting documents are also intended to meet the needs of many different audiences, including policy makers, managers, and others. For example:
-
People who want to purchase authoring tools that are accessible and that produce accessible content can use ATAG to evaluate authoring tools
- People who want to encourage their existing authoring tool to improve accessibility in future versions, can refer the authoring tool vendor to ATAG
Supporting documents are listed under ATAG 1.0 resources on this page, and other resources are listed on the WAI Guidelines and Resources page.
What is in ATAG 1.0
ATAG 1.0 contains 28 checkpoints that cover:
- Authoring practices that result in more accessible content
- Output that meets standards
- User prompts for accessibility-related metadata
- Simple, well-integrated tools for finding and repairing accessibility problems
- Documentation on accessibility features
- A user interface that is itself accessible to people with disabilities
Technical document format
ATAG 1.0, the techniques documents, and the checklist follow the W3C format for technical specifications which includes at the beginning: version links, editors, copyright, abstract, and status with the link to errata and the email address for comments. Most WAI specifications have a link at the top to the Table of Contents.
ATAG Versions: 1.0 and 2.0
Authoring Tool Accessibility Guidelines 1.0 was approved in February 2000 and is the stable and referenceable version.
ATAG 2.0 is being developed to be compatible with WCAG 2.0, which is under development, and WCAG 1.0, which is already a W3C Recommendation. WAI anticipates ATAG 2.0 may be completed in the first half of 2005. Because of the nature of the W3C specification development process, WAI cannot be certain when the final version of ATAG 2.0 will be available. Therefore, ATAG 1.0 will remain the latest approved version at least into the beginning of 2005.
Who develops ATAG
ATAG technical documents are developed by the Authoring Tool Accessibility Guidelines Working Group (AUWG), which is part of the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI). For more information about the working group, see the AUWG page.
The W3C specification development process includes formal periods for public review. Opportunities for review and comment of WAI documents are announced on the WAI home page and WAI Interest Group mailing list. An email address for sending comments is included in the "Status of this Document" section.
Opportunities for contributing to ATAG and other WAI work are introduced in Participating in WAI.
