The EPUB\u00ae specification is a distribution and interchange format standard for digital publications and documents. EPUB defines a means of representing, packaging and encoding structured and semantically enhanced Web content \u2014 including HTML5, CSS, SVG, images, and other resources \u2014 for distribution in a single-file format.<\/p>\n
EPUB 3, the third major release of the standard, consists of a set of four specifications, each defining an important component of an overall EPUB Publication:<\/p>\n
-EPUB Publications 3.0 [Publications30], which defines publication-level semantics and overarching conformance requirements for EPUB Publications.<\/p>\n
-EPUB Content Documents 3.0 [ContentDocs30], which defines profiles of XHTML, SVG and CSS for use in the context of EPUB Publications.<\/p>\n
-EPUB Open Container Format (OCF) 3.0 [OCF3], which defines a file format and processing model for encapsulating a set of related resources into a single-file (ZIP) EPUB Container.<\/p>\n
-EPUB Media Overlays 3.0 [MediaOverlays30], which defines a format and a processing model for synchronization of text and audio.<\/p>\n
EPUB has been widely adopted as the format for digital books (eBooks), and these new specifications significantly increase the format's capabilities in order to better support a wider range of publication requirements, including complex layouts, rich media and interactivity, and global typography features. The expectation is that EPUB 3 will be utilized for a broad range of content, including books, magazines
and educational, professional and scientific publications.<\/p>\n
This document provides a starting point for content authors and software developers wishing to
understand these specifications. It consists of non-normative overview material, including a roadmap to
the four building-block specification documents that compose EPUB 3.<\/p>\n
Another non-normative document, EPUB 3 Changes from EPUB 2.0.1 [EPUB3Changes], describes
changes in EPUB 3 from the previous version, but is intended primarily for Authors and EPUB Reading
System vendors migrating from EPUB 2.0.1 to EPUB 3 and for those who anticipate supporting both versions.<\/p>\n","protected":false},"excerpt":{"rendered":"
