View Full Version : Book ID in an EPUB file

12-13-2010, 12:04 AM
Hi there,

does anyone know about the book ID generated in the ePUB file? I'm just wondering how and when to use it? Indesign CS5 will auto generate the Book ID but do we need to delete it or just leave it blank?

ID auto generates the BookID....leave it. It's needed.

<package xmlns="" unique-identifier="bookid" version="2.0">

<dc:identifier id="bookid">urn:uuid:ba151a94-2581-dbd1-144a-3ae968f738c7</dc:identifier>
