Following the decision to outsource embossing at the Swedish Library of Talking Books and Braille, an idea for a braille embossing format is proposed by Stig Becker to the Swedish Braille Authority.
The Swedish Braille Authority orders a pilot study on the subject from Fredrik Larsson.
The first draft of the PEF specification is written by Joel Håkansson with the guidance of braille experts Björn Westling and Björn Nyqvist.
The draft is presented to the Daisy Consortium working group “Braille in Daisy” where, among other things, the format gets its name.
Joel Håkansson, Björn Westling and Björn Nyqvist continue work on the specification and meet with Braillo and Index Braille to discuss support for PEF in their embossers.
Support for PEF is implemented in Daisy Pipeline.
The specification is presented at the Daisy board meeting in Kyoto, supported by several braille organizations around the world.
Sensus, Denmark incorporates PEF support in their braille service.
The Swedish Library of Talking Books and Braille, The Norwegian Library of Talking Books and Braille and The National Agency for Special Needs Education and Schools begins using PEF in their daily production.
Bert Frees joins the development of Braille Utils and rapidly increases the number of embossers.
Joel Håkansson and Björn Westing are awarded by FFS (www.ffss.se) for their work on PEF.
The PEF Format receives the Braille 21 Award.
