The Roles defined in this specification provides user interface designers with the ability to add extra semantic role
information.
The goal is to make static and interactive content of Web pages more usable and accessible to their users and their
assistive technologies. This goal is achieved by providing a cross-platform role model for dynamic Web content that allows
for content adaptations based on role information. The result is to provide an interoperable way for associating behaviors
with document-level markup.
The PF working group has developed a roadmap on making dynamic web content more accessible to people with disabilities. To assure these technologies will interoperate in a manner that improves accessibility for the widest range of web technologies, the PF wokring group asks for comments and suggestions on how this specification can be improved for use in the technologies that you or your working group are developing. In general we prefer public comments so that all people (includig the general public) reviewing the document can be aware of your comments, but you may also send member confidential comments that will be available only to the working group and other W3C members.

This document is an internal Working Draft by the Protocols & Formats Working Group of the Web Accessibility Initiative.
This specification adds semantics to content to improve the accessibility and interoperability of Web Content and Applications. This document and the States and Adaptable Properties Module are the result of the gap analysis of the DHTML accessibility roadmap to enable accessible dynamic Web content and applications. The Working Group expects to advance this document to a Working Draft and Recommendation.

This section is informative.
Roles are a simple way for an author to make custom widgets (new interactive elements) accessible and interoperable by encapsulating the functional substructures in a page. The user agent or operating system then knows how to handle the element by mapping the role to an adaptive interface or to the accessibility API (Accessible Programmable Interfaces) of the operating system.
Web applications typically rely on standard web markup (HTML) with code called JavaScript (also known as dynamic HTML or DHTML) running on top of them. Each platform (Windows, Linux, Sun) has an operating accessibility API (application programmable interface) with the notion of a role for interface (GUI) objects. However, JavaScript needs an accessibility architecture to write to that map to the accessibility frameworks on the native platform by the user agent. Further, authors of JavaScript generated content do not want to tie themselves to the standard tag elements that define the actual user interface element (such as tables and ordered lists) that can easily be understood and manipulated accessibly. Adaptive technologies, that need to provide alternative access to complex user interfaces authored via HTML, are often left guessing at the semantics behind portions of HTML documents.
Using this specification you can assign a role name to an object that maps the object to the accessibility framework on the native platfom and provides semanitcs needed by adaptive technologies. For assigning meaningful properties that change with time and events see the WAI States and Adaptable Properties Module.
This draft currently handles two aspects of roles - GUI functionality and structural relationships of the element. For
more information see the Dynamic Accessible Web Content Roadmap Roadmap and
implementation examples for the use of roles making
dynamically generated content accessible.
This taxonomy is designed in-part to support the common roles found in platform accessibility API (Accessible
Programmable Interfaces) frameworks. Reference to roles found in this taxonomy by dynamic Web content may be used to
support dynamic accessible content authoring, interoperability with assistive technologies.
The schema to support this standard has been designed to be extended so that custom roles can be created while providing a
common schema for describing how to interact accessibly with a custom role. See extending accessible roles.
At some point the working group intends to add roles for A, Adding concepts in the type of content for adaptation to the user scenario and B, Knowledge representation of Web content.In future versions of this specification the working group intend to add roles in support of individualized content adaptation and knowledge representation of Web content.
This section is informative.
This example shows a role being used to make a simple widget known to the user agent, so that the user agent knows how
to handle it.
Roles can be embedded in any host language, e.g. [XHTML] 1.1. In this example, a table has been
assigned the role of a spread sheet.
<table id="table1" x2:role="wairole:spreadsheet" >
Encapsulated in the role information is information for the operating system that enables it to be properly treated. (In
this case that multiselectable is supported.)
A full spreadsheet example is available online at http://www.mozilla.org/access/dhtml/spreadsheet
In many case Roles will work well with other supporting technologies, such as XHTML 1.1 For Accessible Adaptable Applications and xml-events.
This section is informative.
While some terms are defined in place, the following definitions are used throughout this document. Familiarity with W3C XHTML 1.1 Recommendation [XHTML] and the W3C XML 1.0 Recommendation [XML] is highly recommended.
This section is normative.
The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
Roles for RDF and XML is not a stand-alone document type. It is intended to be integrated into other host languages such as XHTML. A conforming document requires only the facilities described as mandatory in this specification and the facilities described as mandatory in its host language. Such a document must meet all the following criteria:
The document must conform to the constraints expressed in Appendix a - RDF Schema combined with the constraints expressed in its host language implementation.
The document must contain an xmlns
declaration for the Role namespace. The namespace for Roles is
defined to be
http://www.w3.org/2005/01/wai-rdf/GUIRoleTaxonomy#
An example start tag of a root element might look like:
<html xmlns="http://www.w3.org/2002/06/xhtml2" xml:lang="en"
xmlns:wairole="http://www.w3.org/2005/01/wai-rdf/GUIRoleTaxonomy#" >
Note: In XML languages without the Role attribute name included, the Role attribute name can be added from the XHTML2
namespace.
For example:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:x2="http://www.w3.org/2002/06/xhtml2" xmlns:wairole="http://www.w3.org/2005/01/wai-rdf/GUIRoleTaxonomy#">
When Roles are included in a host language, all of the facilities required in this specification must be included in the
host language.
A conforming user agent must reference the role information reference in the DOM.
However it is advised that a conforming user agent also allows for roles to be extended via a RDF . When a role from a
different specification extends or inherits from a role in this specification, then that role should also be supported at
least to the extent that the original role is supported.
This section is normative.
This specification defines a Taxonomy called Role. The Roles Taxonomy uses the XML namespace [XMLNAMES] identifier
http://www.w3.org/2005/01/wai-rdf/GUIRoleTaxonomy#
All examples are informative. Examples in this document that use the namespace prefix "wairoles" all assume a valid xmlns declaration
xmlns:wairoles="
http://www.w3.org/2005/01/wai-rdf/GUIRoleTaxonomy#"
in the document involved.
The remainder of this section describes the classes instances and properties in this taxonomy, the semantics, and provides an RDF Schema as required in [RDF ].
In this example a div has been used in place of a standard form element checkbox. A role is used to make the behavior of the simple widget known to the user agent.
<span class="checkbox" id="chbox1" x2:role="wairole:checkbox" tabindex="0"
onkeydown="return checkBoxEvent(event);" onclick="return checkBoxEvent(event);" >
A checkbox label
</span>
The schema may look something like the following:
<rdf:Description rdf:ID="Checkbox">
<rdf:type rdf:resource="#Select"/>
<baseConcept>http://www.w3.org/MarkUp/HTML#checkbox</baseConcept>
<supportedState>waistates:multiselect</supportedState>
</rdf:Description>
In this example a Checkbox is defined as a type of select, but represents the same concept Checkbox as in the [HTML] specification. Although it inherits all the supported states of a select, we also expect it to support multiselect. Note that much of this could be formalized in XML schema of XSD. However being able to define similarities between roles, such as baseConcepts and more descriptive definitions would not be available in XSD.
Roles are defined and described by their properties. Properties define the structural function of a role, such as: What
a roles is, concepts behind it , what it can contain, what it must contain.
In the case of widgets this also includes how it interacts with the user agent based on mapping to [HTML] forms and XFORMS, allowed states and required states.
The are three properties that describe the relationship between concepts. They are:
Type and subclasses- (from RDFS) this implies inheritance, which means, among other things, the inheritance of limitations and properties. Other than well known stable specifications, inheritance may be restricted to items defined inside this specification so that items that can not be changed and affect inherited classes.
For example: Buttonundo is a subclass or type of a button. If we change the properties and expected behavior of a button then the properties and behavior of buttonundo will also change.
relatedConcept - A relatedConcept is a similar or related idea from other specifications Concepts that that are related are not necessarily identical. relatedConcepts do not inherit properties from each other. Hence if the definition of a type changes, the properties, behavior and definition of a relatedConcept is not affected.
For example: A grid is like a table. Therefore, a grid has a relatedConcept of a table as defined at http://www.w3.org/TR/html4/struct/tables.html#edef-TABLE. However if the definition of table is modified our definition of a grid will not be affected.
baseConcept - A baseConcept is like a relatedConcept except that a baseConsepts are almost identical. BaseConcept is similar to type, but without inheritance of limitations and properties. baseConcepts are designed as a substitute for inheritance for external concepts.
For example: the checkbox defined in this document has the same functionality and anticipated behavior as a checkbox defined in http://www.w3.org/MarkUp/HTML#checkbox.
Therefore, a checkbox has a baseConcept of a checkbox as defined at http://www.w3.org/MarkUp/HTML#checkbox. However if http://www.w3.org/MarkUp/HTML#checkbox is modified, the definition of a checkbox in this document will not be not affected.
The Roles Taxonomy supports the following additional properties:

Estimated importance of a role to completion of the main tasks of a delivery unit. For example a main menu is
typically required for a user to beale to completer the main tasks of a site. A secondary side menu is typically
less important. Hence a main menu has an importance level of one and secondary side menu may have an importance
level of 0.6. |

nameRef |
How a role type name is extracted and referenced inside a document. For example the DOM might reference a role by it's title. |
Any valid RDF object reference, such as a URI or RDF ID. Recomended values: Child, title, content. |
To support the current user scenario this specification defines roles that A, help define Widgets (For example, a tristate Checkbox) and B, help define page structure (for example, a section header).

The following roles are used as base types for applied roles. They are not used by Web Authors and would not be exposed as role definitions for incorporation into a Web page. Base classes are referenced within the taxonomy and are used to build a picture of the role taxonomy class hierarchy within the taxonomy.

button |
Allows for user-triggered actions. Buttons are mostly used for discrete, atomic actions. Its value is cognitive; the idea that this is a user action opportunity is made very clear by making it look like a front-panel button on a device. The animation of the button in response to indirect (by mouse) manipulation fosters the illusion of direct manipulation and keeps user cognition in sync with the UI perception of user action events. Standardizing the appearance of buttons enhances recognition as buttons and arraying them compactly in toolbars, for example. |

Roles for document structure are also required to support the accessibility of dynamic Web content to assist adaptive
technology in determining active content vs. static document content. Structural Roles, by themselves do not all map to
accessibility API's, but are used to create widget roles or assist content adaptation.
This schema is likely to evolve as new use cases are added to the scope of this specification.

presentation |
An element who's role is Presentational does not need to be mapped to the accessibility API. Intended use is when an element is used to change the look of the page but does not have all the functional, interactive, or structural relevance implied by the element type. Example use cases:
The user agent may remove all structural aspects of the element being repurposed. For example a table marked as presentation would remove the table, td, th, tr, etc. elements while preserving the individual text elements within it. Because the AT knows to ignore the structural aspects implied in a table, no harm is done by using a table for layout. |

Use case: In an email application it has a document and an application in it. The author would want to use typical application navigation mode to cycle through the list of emails. Much of this navigation would be defined by the application author. However, when reading an email message the ATV will want to switch to a document mode where it controls browsing navigation. |

A visual presentation of a section. Tabpanels are commonly used in applications that have a large number of options that can be categorized in logical groups. The Tabpanels serve three functional components, including a menu bar of groupings, a selected grouping and set of resources associated with that group. Each tab in a tablist serves as both a menu item and as a title for the tab content associated with the tab. In graphical renderings the selected Tab and TabContent usually share the same background color and the non-selected tabs have a different background color to make the selected Tab and TabContent stand out visually and provide a visual association with the Tab and TabContent. Only one tabpanel's contents is visible at a time. |

A tab is a tabpanel header. Tab is used as a grouping label, providing a link for selecting the resources associated with the group to be rendered to the user. One of the tabs in tablist must be the current tab and the tabpanel, associated with the tab, must be rendered to the user. Other tabpanels are typically hidden from the user, until the user selects the tab associated with that tabpanel. The currently selected tab should be marked with selected=true.tablist is the container for a set of elements with the role attribute set to tab. Only one tab may be selected at a time. At any time, one tab must selected. |
