Roles for Accessible Rich Internet Applications (WAI-ARIA Roles) Version 1.0 — An RDF Role Taxonomy with QName Support for Accessible Adaptable XML Applications

Lisa Seeman, Michael Cooper


Accessibility is often dependent on Assistive Technology (AT), tools that provide alternate modes of access for people with disabilities by transforming complex user interfaces into an alternate presentation. This transformation requires information about the role, state, and other semantics of specific portions of a document to be able to transform them appropriately. Rich Web applications typically rely on hybrid technologies such as DHTML and AJAX that combine multiple technologies: SVG, HTML and JavaScript for example. The various technologies provide much but not all of the information needed to support AT adequately. This specification provides a Web-standard way to identify roles in dynamic Web content. The result is an interoperable way to associate behaviors and structure with existing markup. This document and the States and Properties Module for Accessible Rich Internet Applications (WAI-ARIA States and Properties) fill information gaps identified by the Roadmap for Accessible Rich Internet Applications (WAI-ARIA Roadmap). The role attribute defined in the XHTML Role Attribute Module is the preferred way to expose these roles in XHTML applications.
