An accessibility checker for LibreOffice and OpenOffice.org writer

Abstract

OpenOffice.org Writer and LibreOffice Writer both implement the OpenDocument Format (ODF) and support output formats such as PDF and XHTML. Through the extensions odt2daisy and odt2braille (developed in the context of the AEGIS project) Writer can also export to DAISY (audio books) and Braille. In order to output usable DAISY or Braille, authors first need to create an accessible source document. The objective of AccessODF, the accessibility checker developed in the context of the European AEGIS project, is to support authors in creating accessible ODF documents and to prepare these documents for conversion to DAISY and/or Braille. The paper discusses the user interface options that were explored, describes how authors can repair errors and warnings, gives examples of automatic and semi-automatic repairs supported by the checker, and describes which errors and warnings are implemented. © 2012 Springer-Verlag.
