Accessibility Guidelines and Regulations

When you review available accessibility guidelines/regulations, you will encounter numerous acronyms and standards including WAI, WCAG, ARIA and Section 508. Let's take a quick look at the relationships between accessibility-related guidelines/regulations.

Web Accessibility Initiative (WAI), a part of The World Wide Web Consortium (W3C), publishes Web Content Accessibility Guidelines (WCAG 2.0) which include guidelines for Accessible Rich Internet Applications (WAI-ARIA). All these guidelines have a lot in common with the regulations imposed on software by national governments. In United States, the goverment-imposed standard is most commonly referred to as Section 508. The full name is "Section 508 of the Rehabilitation Act of 1973, as amended in 1998 (29 U.S.C. § 794 (d))". This set of regulations is a must-follow for all software companies that develop software to be used by government agencies.
