  • • describes the context of a role, for example a listitem should be inside a list;
     
    • defines a hierarchy of roles with related properties, for example a directory is a type of list;
     
    • makes use of OWL to provide a type hierarchy allowing for semantic inheritance similar to a class hierarchy;
     
    • makes references to related concepts in other specifications;
     
    • provides descriptions for each role;
     
    • describes what states are supported for each role, for example, a checkbox supports being checked.
  • Use native markup when possible
  • For example, with XHTML it is better to use the native checkbox than to use a div element with role checkbox as these should already be accessible through your browser

  accessibility

  • Complex web applications become inaccessible when assistive technologies cannot determine the semantics behind portions of a document or when the user is unable to effectively navigate to all parts of it in a usable way (see the Roadmap for Accessible Rich Internet Applications [ARIA-ROADMAP]). ARIA divides the semantics into roles (the type defining a user interface element) and states and properties supported by the roles.

     

    Authors must associate elements in the document to an ARIA role and the appropriate attributes (states and properties) during its lifecycle.

     

     

    2.1. WAI-ARIA Roles

     

    An ARIA role is set on an element using the a role attribute similar to the one defined in the XHTML Role Attribute  Module [XHTML-ROLES].
  • Use native markup when possible
  • Apply the appropriate roles from ARIA
  • Preserve semantic structure
  • Build relationships
  • Set and properties in response to events
  • Support full, usable keyboard navigation
  • Synchronize the visual UI with accessibility states properties for supporting user agents
