Accessible Rich Internet Applications (ARIA)

In order to allow assistive technologies to convey appropriate information to persons with disabilities, web content requires semantic information about controls, structures, and behaviors. The Accessible Rich Internet Applications (WAI-ARIA) specification helps to define accessible user interface elements by providing an set of roles, states, and properties that can be used to improve the accessibility and interoperability of web content and applications. These semantics are designed to allow an author to properly convey user interface behaviors and structural information to assistive technologies in document-level markup.
