A

At least one navigation file, like navigation.xml, is required for an EPUB 2.0.1 book in the book ZIP container. It provides navigation information like a table of contents of the book.

Here is the requirement on a navigation file:

1. A navigation file should be named with .xml file extension.

2. A navigation file must be an XML file and meet the "Navigation Center eXtended (NCX)" specifications.

3. A navigation file must specify a "dtd:uid" meta element in the "head" element.

4. A navigation file must provide a title with the "docTitle" element.

5. A navigation file must provide the "navMap" element with a list of "navPoint" sub-elements.

You can create a navigation file with any text editor. Here is an example called navigation.xml:

<?xml version="1.0" encoding="utf-8"?>
<!-- navigation.xml

<ncx xmlns="http://www.daisy.org/z3986/2005/ncx/" version="2005-1">
    <head>
        <meta content="id" name="dtb:uid"/>
    </head>    
    <docTitle>
        <text>Hello</text>
    </docTitle>
    <navMap>
        <navPoint id="link1">
            <navLabel>
                <text>Hello</text>
            </navLabel>
            <content src="content.xhtml"/>
        </navPoint>
    </navMap>
</ncx>
