One ?le

Bene?ts

a single ?le)
? Facilitates quality control

? Followed by ereader manufacturers and
ebook production people alike
? For differently-able ereaders, use
progressive enhancement and graceful
degradation
Standards

EPUB3 in old ereaders
? Designed to be backwards compatible
? What did use to work in an old ereader
mostly still does.
? What didn't use to work still won't.

Minimal changes to
convert to EPUB3
? Changes to content.opf ?le (including
metadata)
? Navigation ?le (toc.ncx and new TOC)

Structure of EPUB3

Required changes to
content.opf
? Version number in package element:

Required changes to
content.opf
? dcterms:modi?ed and dc:identifer

Required changes to
content.opf
? properties="nav" in NAV item manifest

Recommended changes
to content.opf
? properties="cover-image" in cover image
item manifest

Things you still need
? dc:title, dc: language

More on dc:title
? dc:title has new possibilities
Once you've added an id, you can add
information about the title.And create a
subtitle, and information about it.

But...
? dc:title's new possibilities are not yet
supported, and ereaders don't know what
to do with multiple dc:title elements

More metadata
? Other metadata is still recommended:
dc:date, dc:publisher, etc.
? EPUB3 offers meta elements with re?nes
attribute for adding additional metadata

You don't need...
? The <guide>
The only ereaders who used it now use
EPUB3 navigation landmarks, which I'll get
to shortly.

The new Navigation
? For both kinds of TOC
? Unlike toc.ncx, it's a regular XHTML ?le
? Regular content with some special
formatting

TOC in the Nav ?le
? Regular XHTML ?le, except for special
formatting: nav is just the start

The new TOC
? Used both for navigational system and as
content right in ebook
?

Kindle Fire and old Kindle
both use new TOC

Old ereaders still use
ncx for navigation
? The XHTML ?le still works as content, but
older ereaders will use toc.ncx for
navigational menu

More 'nav': landmarks
? New way to specify cover, toc, index, and
starting page.
? Key bit is epub:type="landmarks" in nav
elemnt

Landmarks

Page markers in text
? Add an id and the all-important important
epub:type="pagebreak"

More 'nav': page-list
? Specify page list with nav and
epub:type="page-list"

Source for page
numbers
? The dc:source element can be used to
show which edition of the book the page
numbers correspond to

Readium uses the page-list to create a menu
for navigating quickly through the book

Page-list in Azardi

Content ?les
? HTML5 but with XHTML syntax
