리치 인터넷 어플리케이션 접근성 (ARIAAccessible Rich Internet Applications)는 (특히 AJAX와 JavaScript를 사용하여 개발하는)웹 콘텐츠와 웹 어플리케이션을 제작할 때 장애인을 위한 접근성 향상 방법을 정의하고 있습니다. 예를 들어, ARIA는 접근가능한 네비게이션에 표시를 한다거나, JavaScript 위젯 사용이나, form 힌트 및 에러 메시지 그리고 실시간 콘텐츠 업데이트 등을 사용할 수 있도록 합니다.

ARIA는 어떤 마크업 요소에도 추가 가능한 접근성 속성의 집합이지만, 특히 HTML에 최적화되어 있습니다. role속성은 객체(article, alert, slider와 같은 것들)의 제너럴 타입을 정의할 수 있습니다. 추가로 ARIA 속성들은 form을 위한 설명이나 progressbar의 현재 값을 나타내어 주는 것과 같은 다른 유용한 프로퍼티들을 제공합니다.

ARIA는 대부분의 유명 브라우저들과 스크린리더에서 지원합니다. 그러나, 구현방식이 가지각색이며 오래된 기술들이 그를 잘 지원하지 않거나 전체를 지원하지 않습니다. "안전한" ARIA를 우아하게 낮추거나, 유저들에게 새로운 기술로 업그레이드 할 것을 요구하는 것 중 하나를 사용하십시요.

다음 사람들을 위해 ARIA를 좋게 만들고 기고해주시길 바랍니다! 시간이 없으신가요? 여기 토론 페이지에 의견을 추가해주셔도 됩니다.

위젯을 위한 ARIA

Keyboard Navigation and Focus for JavaScript Widgets
The first step in developing an accessible JavaScript widget is to make it keyboard navigable. This article steps through the process. The Yahoo! focus management article is a great resource as well.
Style Guide for Keyboard Navigation
A challenge with ARIA is getting developers to implement consistent behavior -- clearly best for users. This style guide describes the keyboard interface for common widgets.

표준화를 위한 노력

WAI-ARIA Activities Overview at W3C
Authoritative Overview of WAI-ARIA Standardization efforts by the Web Accessibility Initiative (WAI)
WAI-ARIA Specification
The W3C specification itself, useful as a reference. Note that, at this stage, it is important to test compatibility, as implementations are still inconsistent.
WAI-ARIA Authoring Practices
Like the W3C WAI-ARIA specification, the official best practices represents a future ideal -- a day when authors can rely on consistent ARIA support across browsers and screen readers. The W3C documents provide an in-depth view of ARIA.

For now, web developers implementing ARIA should maximize compatibility. Use best practices docs and examples based on current implementations.
Open AJAX Accessibility Task Force
The Open AJAX effort centers around developing tools, sample files, and automated tests for ARIA.
Under Construction: WCAG 2.0 ARIA Techniques
The community needs a complete set of WCAG techniques for WAI-ARIA + HTML, so that organizations can be comfortable claiming their ARIA-enabled content is WCAG compliant. This is mostly important when regulations or policies are based on WCAG.
