EPUB solves all the flaws related to PDF and developer friendliness. An EPUB is a simple ZIP format file (using the .epub extension) that contains files arranged in a predefined way. Otherwise, EPUB is very simple:
Function introduction
1. Everything in epub is basically XML. EPUB files can be created using standard XML tools and do not require any specialized or proprietary software.
2. EPUB content (the specific content of eBooks) is basically XHTML 1.1 (another format is DTBook, a standard for encoding books for people with limited vision. For more information about DTBook, see Resources, which is not covered in this tutorial).
3. Most EPUB XML schemas come from off-the-shelf, freely available, published specifications.
The most critical thing is that EPUB metadata is XML and EPUB content is XHTML. If your document building system produces results for the web and/or is XML-based, it can also be used to generate EPUB. At present, many companies, represented by Google and Apple, use EPUB as the format of digital books.
