eBF leads to a database not only the entire InDesign document contents, but also the absolute totality of the format. Even things like kerning or adjustment to baseline grid. Therefore we can say that eBF contains a mirror image of the paper version, perfectly synchronized. In addition, the format chosen to save the information, XML, ensures instant portability to almost any other format. The result: cross-media publication in one step.
Having the content with all his wealth in a database, in XML format, is the best way nowadays to get any output format. eBF can apply XSL, XSL-FO and CSS to content. But in addition to apply transformations and styles, eBF can perform additional actions, prior to or after processing, to complete the preparation of files, like collecting other components and packaging them toghether, such as with formats epub and Mobipocket.
eBF brings the efficiency of editorial systems to the book arena. The resources are distributed appropriately and immediately. Labeling tasks can be performed by unqualified personnel, XML programming requires no permanent staff in the company... eBF can produce many formats in a fraction of the time you need to produce one. See for yourself.
If eBF was a converter or editor of ebooks, its functional horizon would be limited by the formats battle. But eBF is a complete cross-media system, where you can devise a business plan not limited to a single fashion. For example, you can design an strategy for B2B content while organizing a site and the sale of epubs.
