IBM added a delicious twist on its new commitment to help OpenOffice.org battle Microsoft Office by donating code that was originally derived in part from a Microsoft-developed technology.

IBM’s iAccessible2, code-named Project Missouri, is a specification for technology used to help the visually impaired interact with Open Document Format (ODF)-compliant applications and was developed in part using Microsoft Active Accessibility (MAA) as a starting point.

IBM developed code from the specification and uses it within its own products such as Lotus Notes. In addition, IBM has implemented in code its IAccessible2 specification, which makes accessibility features available to the visually impaired, and plans to donate that to the OpenOffice.org effort (see related story).

Project Missouri was an independent interface built on top of MAA that extends the technology, according to IBM. The company has since donated the iAccessible2 specification to the Linux Foundation, but the code IBM developed using the specification is headed for OpenOffice.org, an open-source collection of applications.

MAA is based on the Component Object Model (COM) and “improves the way accessibility aids (specialized programs that help people with disabilities use computers more effectively) work with applications running on Microsoft Windows,” according to the Microsoft Web site.

IBM introduced iAccessible2, which can run on Windows or Linux, late last year as a set of APIs that makes it easy for visuals in applications based on ODF and other Web technologies to be interpreted by screen readers that reproduce that information verbally for the blind.

ODF is the foundation for OpenOffice.org applications, which include a text editor, spreadsheet, presentation graphics program and a database. It has been positioned as an alternative to Microsoft Office.

Accessibility is a big issue among adopters of productivity applications, especially governments who must have tools that are available to a broad segment of end-users.

Massachusetts, a pioneer in the adoption of open document formats, has delayed its migration away from Microsoft Office and its rollout of ODF-based applications for the sole reason that those applications lack the needed accessibility features.
