Daisy, NIMAS, Braille Conversion

The DAISY (Digital Accessible Information System) is a technical standard for the electronic publication which brings together text, audio and images into a single accessible, navigable digital talking book. It is a new file format based on an ANSI NISO standard and the text portions of it are referred to as DTBook, an XML standard coordinated by DAISY Consortium and the Library of Congress’ National Library Service for the Blind and Physically Handicapped (NLS). The Daisy format includes the benefits of a range of audio features, full text - allowing navigation, as well as search and find features and the ability to add bookmarks and footnotes. A DAISY talking book can be read on a PC with a CD drive and a specific reading program or in a special talking book player.

Our XML conversion team has got wide expertise in DAISY standards and conventions like ANSI/NISO Z39.86, specifications laid by DAISY Consortium. We have been offering DAISY conversion service to publishers, libraries, Universities, Government organizations from various parts of the world and can easily convert documents from most of the digital formats as well as hard copies to Daisy format.

NIMAS (National Instructional Materials Accessibility Standard) is a technical standard used by publishers to produce source files (in XML) that may be used to develop multiple specialized formats (such as Braille, DAISY talking books, Large prints or HTML) for students with print disabilities. The NIMAS specification is a subset of the ANSI/NISO Z39.86-2005 standard that is also used as the standard for DAISY 3.0 digital talking books.

DiTech has expertise in managing large NIMAS conversion projects as per the NIMAC compliance. We have helped many publishers in converting their print media and almost all digital formats like word, PDF, Indesign, Quark etc. to XML-based NIMAS files. These files have been validated against the standard and evaluated for their usability with DAISY readers.

Braille is a system widely used by blind and visually impaired people to read and write. It is made up of embossed dots in a material that represent letters, punctuation marks, numbers, musical notation, computer code, and scientific symbols. Braille has now been adapted to almost every known language and has revolutionized life for blind and visually impaired people. DiTech has expertise and is a master in the art of converting text into Braille. With our in-house tested tools and processes we can convert Braille documents in Grade 1 (words are formed from letters in the usual alphabetic way) or Grade 2 (written with abbreviations and contractions). A review of the Braille document is done by an expert with knowledge of Braille to ensure the quality.
