Contentra Technologies is officially recognized by the CAST NIMAS Development and Technical Assistance Center as a NIMAS content conversion service provider. In addition to the many formats to which we convert files, Contentra actively offers NIMAS conversion services and workflows to major publishers throughout the world, including many in the US.

In 2002, the Department of Education authorized the Center for Applied Special Technology (CAST) to establish technical specifications for a voluntary National Instructional Materials Accessibility Standard (NIMAS). NIMAS helps to increase the availability and quick delivery of print educational materials in accessible formats to blind or other persons with reading disabilities in the K–12 setting.

State and local educational agencies complying with NIMAS will require publishers to submit NIMAS file sets to the National Instructional Materials Access Center (NIMAC) when contracting for the purchase of the instructional materials. The NIMAC serves as a national repository for NIMAS files. It is also a conduit through which NIMAS files are made available to authorized users so that these files may be converted into fully accessible textbooks and instructional materials for students with qualifying disabilities.

The NIMAS outlines a set of consistent and valid XML-based source files to be created by K–12 curriculum publishers or other content producers. We help publishers convert their materials to the NIMAS standard. Files can then be delivered via various types of media—CD-ROMs, DVDs, PDFs, application files, Web sites, etc.

The following are examples of such workflows:

  • Convert Word/PDF book file to a NIMAS XML/NIMAS XHTML file
  • Generate NIMAS-compliant XML files in book publishing workflow
  • Create NIMAS-compliant Web sites
  • Create NIMAS-compliant mobile XHTML files

Contentra assists publishers in converting their print/electronic media to NIMAS 1.1/DAISY/DTBook-compliant format using our proprietary workflows. Our services also include delivering the NIMAS file set to the NIMAC engine.

All NIMAS conversion projects are delivered in accordance with the highest quality standards and with adherence to strict delivery schedules. We convert more than 1 million pages annually.



Daisy & Braille


As a leading content conversion service provider, Contentra Technologies actively supports the DAISY vision to promote international standards and technologies. We enable equal access to information and knowledge by all people with reading disabilities, which also benefit the wider community. Contentra currently offers DAISY conversion services and workflows to major libraries, organizations, and publishers worldwide.

Complying with DAISY requires converting file sets to one or the other of the DAISY standards. DTBs produced are in and of themselves independent of the distribution medium, that is, the digital master file can be archived and may also be distributed on currently available media such as CDs or DVDs. As technology advances and digital media distribution methods evolve, these same books can be distributed via the newly developed media or system.

The DAISY Standard allows the producing agency full flexibility regarding the mix of text and audio, ranging from audio-only to full text and audio to text-only. A DAISY book can be defined as a set of digital files that includes:

1. Audio with NCX: DTB with structure. The NCX is the navigation control center, a file containing all points in the book to which the user may navigate. The XML textual content file, if present, contains the structure of the book and may contain links to features such as narrated footnotes, etc. Some DTBs of this type may also contain additional textual components, for example, index or glossary, supporting keyword searching.

2. Audio and full text: DTB with structure and complete text and audio. This form of a DTB is the most complete and provides the richest multimedia reading experience and the greatest level of access. The XML textual content file contains the structure and the full text of the book. The audio and the text are synchronized.

3. Text and no audio: DTB without audio. The XML textual content file contains the structure and full text of the book. There are no audio files. This type of DAISY DTB may, for example, be rendered with synthetic speech or with a refreshable Braille display.

Contentra assists publishers in converting their print/electronic media to DAISY/DTBook-compliant format using our proprietary workflows.

The following are examples of such workflows:

  • Convert Word/PDF book file to a DAISY XML/DAISY XHTML file
  • Generate DAISY-compliant XML files in book publishing workflow

All DAISY conversion projects are delivered in accordance with the highest quality standards and with adherence to strict delivery schedules. We convert more than 2,500 titles/500,000 pages annually.

The DAISY reader player application launched at the 2011 CSUN Conference held in San Diego.

Contentra Technologies, in collaboration with xml-tekst, developed "ida-reader" for the dyslexic and visually impaired community. This product was launched at the 26th Annual CSUN Conference 2011 in San Diego.

The ida-reader is a user-friendly software product that has the ability to read aloud text content from a variety of file formats such as DAISY 2.0/2.02, DAISY 3.0, HTML, RTF, XML, or the original book pages. The ida-reader reads full text with TTS and also recorded audio.
