platform office suite=> LibreOffice / OpenOffice.org as Braille authoring environment
● Reduce or eliminate the need for editing Braille codes after export
● Emboss directly or just export
AEGIS Final Workshop, Brussels, Belgium, 28 November 2011
odt2braille Objectives
● ODF as source format for both DAISY & Braille● Useful for Braille & DAISY production
centres● High flexibility
AEGIS Final Workshop, Brussels, Belgium, 28 November 2011
How?
● Build LibreOffice / OpenOffice.org extension
● Reuse existing tools:● liblouisxml: open-source library for
Braille transcription of XML docs● liblouis: Braille translation engine● BrailleUtils: library for embossing and
converting PEF files (Portable Embosser Format)

embosser-independent; uses XML and Unicode● User preferences stored as metadata● In 17 languages, including English, Dutch, French,
Spanish, Portuguese, German, Swedish, Greek, ...
