15. Things you still need
• dc:title, dc: language
Thursday, May 30, 2013

16. 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.
Thursday, May 30, 2013

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

19. More metadata
• Other metadata is still recommended:
dc:date, dc:publisher, etc.
• EPUB3 offers meta elements with refines
attribute for adding additional metadata

The only ereaders who used it now use
EPUB3 navigation landmarks, which I'll get
to shortly.

21. The new Navigation
• For both kinds of TOC
• Unlike toc.ncx, it's a regular XHTML file

formatting

22. TOC in the Nav file
• Regular XHTML file, except for special
formatting: nav is just the start
