Linux Foundation
June 5, 2008

The Open A11y Workgroup in the Linux Foundation works to develop free and o=
standards supporting comprehensive access to information and user interfaces
for persons with disabilities. Our standards process is open to interested
members of industry, developer, and consumer communities. Obtaining public
comment on our proposed standards before they are finalized is one of the m=
important steps in our process. Public review helps ensure our standards are
relevant and complete.


We are now requesting comment on the following specification produced by our
IAccessible2 team. This specification is expected to become a Linux Foundat=
standard this year.



IAccessible2 is a set of Windows accessibility interface definitions which =

complements Microsoft's earlier work on MSAA. The IAccessible2 interfaces f=
critical accessibility gaps in the MSAA offering.  IAccessible2 is an engin=
accessibility interface allowing application developers to leverage their=20
investment in MSAA while also providing an Assistive Technology (AT) access=
to content in rich document applications and web browsers. The additional=20
function includes support for rich text, tables, spreadsheets, Web 2.0=20
applications, and other rich content often found in large, complex applicat=

IAccessible2 is implemented by application developers to allow Assistive=20
Technology, such as a screen reader used by someone who is blind, access to
an application's components, e.g. a table in a word processor.  IAccessible=
has been implemented in applications such as IBM Lotus Symphony and Mozilla=
Firefox 3.  It has also been implemented in the leading Windows screen read=
e.g. JAWS from Freedom Scientific and Window-Eyes from GW Micro. =20

Developers of complex applications benefit because they can provide=20
accessibility to complex components well beyond what is possible with MSAA.=
Application developers also benefit because screen readers already support
applications that implement IAccessible2.  IAccessible2 was a joint effort =
the leading AT vendors. These vendors saw the need for an enhancement to=20
MSAA and worked closely with IBM accessibility architects and engineers
during the definition and implementation of the API.

Users benefit because they have full access to complex applications such=20
spread sheets in IBM Lotus Symphony and ARIA (Accessible Rich Internet=20
Applications) in Firefox 3.

It is also important to note that IAccessible2 has been harmonized with the=
UNIX accessibility APIs to allow for efficient multi-platform development. =

This was done through close collaboration with accessibility architects who=
have intimate knowledge of the UNIX accessibility APIs.
