9 Things You Need to Know About ePub3
1. ePub 3 is enhanced, interactive e-books
ePub 3 is based on HTML5. That brings many benefits (more of which below), but foremost among them is HTML5's capabilities for rich media (audio and video) and interactivity (via JavaScript). Open standard HTML5 is already supported by all modern browsers and is rapidly displacing proprietary alternatives such as Flash Player, Microsoft Silverlight/XAML and forms/scripting within PDFs (which were never widely supported beyond Adobe's own Reader software). And by adopting ePub 3 (and thereby HTML5), you will automatically get the benefits of further improvements in the pipeline of browser technology's rapid-pace evolution. That beats being stuck with expensive native-app codebases, or worse, sole-source proprietary technology neglected—or abandoned—by its vendor.
