iBook Author is another great digital authoring tool, and it can add extra feature with HTML5 Widget.
There are a lot of HTML5 Animator application today, including Adobe Edge.
But I found if you use SVG as graphic asset for Adobe Edge project, then import it into iBook Author as HTML5 Widget, the SVG asset will not show, even you can test it on iBook Author.
From my experiment at the moment, PNG asset is good and appear in iBook Application.
Cheer!
