NATIONAL FOREWORD

This Draft Indian Standard (Part 4) which is identical with ISO/IEC TS 30135-4 : 2014 ‘Information technology - Digital publishing - EPUB 3 - Part 4: Open container format’ issued by International Organization for Standardization (ISO) and International Electro technical Commission (IEC) jointly was adopted by the Bureau of Indian Standards on recommendations of the Data Management System Sectional Committee, and approval of the Electronics and Information Technology Division Council.

Part 1 EPUB3 overview

Part 2 Publications

The text of ISO/IEC Standard may be approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
