This is draft documentation mapping <abbr title="HyperText Markup Language">HTML</abbr> elements and attributes to accessibility <abbr title="Application Programming Interface">API</abbr> Roles, States and Properties on a variety of platforms. It provides recommendations on deriving the accessible names and descriptions for HTML elements. It also provides accessible feature implementation examples.

<p class="warning"><strong>This document is subject to change without notice.</strong></p>
<p>This document was developed by and with the approval of the <a href="http://www.w3.org/WAI/PF/html-accessibility-tf.html">HTML Accessibility Taskforce</a>, a joint task force of the <a href="http://www.w3.org/WAI/PF/">Protocols and Formats Working Group</a> and the <a href="http://www.w3.org/html/wg/">HTML Working Group</a>.</p>

<h2>Introduction: Accessibility <abbr title="Application Programming Interfaces">APIs</abbr></h2>
<p>To provide access to desktop GUI applications, assistive technologies originally used heuristic techniques to determine the meaning of the user interface and built an alternative off screen model. For example, a row of labels displayed horizontally near the top of an application window might be a menu. Labels with a border drawn around them might be buttons. Heuristic techniques are not always accurate, however, and require assistive technologies to be updated whenever the software application is updated.</p>
<p>A much better technique is for the software application to provide the necessary information for interoperability with assistive technology. To meet this need, platform owners have developed specialized interfaces, called accessibility APIs, which can be used to communicate accessibility information about user interfaces to assistive technologies. </p>
<p>In the case of static Web pages, the Document Object Model (DOM) is used to represent the structure and state of the elements in the document being rendered by a user agent. The elements of the document are organized into a hierarchy of nodes known as the <abbr title="Document Object Model">DOM</abbr> tree. For traditional static Web pages, assistive technologies, such as screen readers, interact with user agents using the DOM. For UI elements that are known to be interactive, such as HTML form elements and desktop applications, assistive technologies may use platform accessibility APIs.</p>
<p>Accessibility APIs covered by this document are:</p>
<ul>
<li><a href="http://msdn.microsoft.com/en-us/library/dd373592%28VS.85%29.aspx">Microsoft Active Accessibility (<abbr title="Microsoft Active Accessibility">MSAA</abbr>)</a> with <abbr title="User Interface Automation">UIA</abbr> Express (known as <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd561898%28v=vs.85%29.aspx">IaccessibleEx</a>)</li>
<li><a href="http://msdn.microsoft.com/en-us/library/dd373592%28VS.85%29.aspx">MSAA</a> with <a href="http://www.linuxfoundation.org/collaborate/workgroups/accessibility/iaccessible2">IAccessible2</a></li>
<li><a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ee684009.aspx">User Interface Automation (<abbr title="User Interface Automation">UIA</abbr>)</a></li>
<li><a href="https://developer.gnome.org/atk/stable/">Linux Accessibility Toolkit (<abbr title="Accessibility Toolkit">ATK</abbr>)</a> and <a href="https://developer.gnome.org/libatspi/stable/">Assistive Technology - Service Provider Interface (<abbr title="Assistive Technology - Service Provider Interface">AT-SPI</abbr>)</a></li>
<li><a href="https://developer.apple.com/library/mac/documentation/Accessibility/Conceptual/AccessibilityMacOSX/OSXAXModel/OSXAXmodel.html">Mac OS X Accessibility Protocol (<abbr title="Mac OS X Accessibility Protocol">AX</abbr>)</a></li>
</ul>
<p>If User Agent developers need to expose to other accessibility APIs, it is recommended that they work closely with the developer of the platform where the API runs, and assistive technology developers on that platform.</p>
</section>
<section class='informative'>
<h2>Exposing HTML features that do not directly map to accessibility API properties</h2>
<p>HTML may have features that are not supported by accessibility APIs at the time of publication. There is not a one to one relationship between all features and platform accessibility APIs. When HTML roles, states and properties do not directly map to an accessibility API, and there is a method in the API to expose a text string, expose the undefined role, states and properties via that method.</p>
<p>IAccessible2 and ATK use object attributes to expose semantics that are not directly supported in the APIs. Object attributes are name-value pairs that are loosely specified, and very flexible for exposing things where there is no specific interface in an accessibility API. For example, at this time, the HTML5 <code><a href="http://www.w3.org/html/wg/drafts/html/master/sections.html#the-header-element">header</a></code> element can be exposed via an object attribute because accessibility APIs have no such role available. <!--Specific rules for exposing object attribute name-value pairs are described throughout this document, and rules for the general cases not covered are in State and Property Mapping. --></p>
<p>For accessibility APIs that do not have "object attributes" per se, it is useful to find a similar mechanism or develop a new interface to expose name/value pairs. Under the Mac OS X Accessibility Protocol, all getters are already simply name-value pairs and it is possible to expose new semantics whenever necessary. Keep in mind, this also requires working with the assistive technology developers to gain support for the new semantics.</p>

<h2>HTML Element to Accessibility API Role Mapping Matrix</h2>
<p><strong>Notes:</strong> </p>
<ul>
<li>A ? in a cell indicates the data has yet to be provided.</li>
<li>"Not mapped" (Not Applicable) means the element does not need to be exposed via an accessibility API. This is usually because the element is not displayed as part of the user interface.</li>
<li>User agents should return a user-presentable, localized string value for the Mac Accessibility AXRoleDescription.</li>
<li>All elements having an accessible object in IAccessible2 mapping are supposed to implement IAccessible, IAccessible2 and IAccessible2_2 interfaces</li>
</ul>
