The Protocols and Formats Working Group today published a First Public Working Draft of Core Accessibility API Mappings 1.1 (Core-AAM), which supports the updated Working Draft of Accessible Rich Internet Applications (WAI-ARIA) 1.1. WAI-ARIA provides an ontology of roles, states, and properties that define accessible user interface elements. WAI-ARIA is designed to improve the accessibility and interoperability of web content, particularly web applications. Core-AAM describes how user agents should expose semantics of content languages to accessibility APIs across multiple content technologies (including much of WAI-ARIA). Core-AAM serves as the basis for other specifications to extend the mappings to specific technologies. Learn more from the call for review e-mail and read about the Web Accessibility Initiative (WAI).
