It is an ISO standard (or at least in the way to be): http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=53255
Also, there's some useful information on Wikipedia. I didn't went to it thoroughly, though: http://en.wikipedia.org/wiki/EPUB Maybe Urmas confused EPUB with the Digital Rights Management system (DRM) which is basically proprietary anticopy software, and is supported by EPUB (as a way to avoid piracy and, I guess, to control the market of books). But EPUB is open source, standardized and is the format used by most e-readers (by all, I will say, with the exception of Kindle, which of course has a proprietary file format). And there's no need to use DMR on it. ________________________________ De: Tom Davies <tomdavie...@yahoo.co.uk> Para: Ginterak <m...@interak.com>; "users@global.libreoffice.org" <users@global.libreoffice.org> Enviado: Miércoles 14 de agosto de 2013 17:47 Asunto: Re: [libreoffice-users] Re: Book-writing with Writer Hi :) Does that mean it is an ISO standard? It's a bit unclear who international Digital Publishing Forum are. Are they widely known and accepted or are they just a branch of Adobe or Apple or someone?
