This is why eBook Factory, the cross-media module of Q4, comes to connect XML and InDesign via a bridge named XML labeling. Through this mechanism, the user creates XML from InDesign documents, and thereafter the content in XML and InDesign are permanently linked.
Once done the labeling, we only need to press a button to get the ebook formats we need. And -welcome to "dynamic content"- we can repeat this as many times as we make changes in InDesign documents. If desired, you can also modify the contents without having to launch this application, using the XML editor of the system.
The appearance of the ebooks will depend on the XSL transformation sheets and CSS style sheets. Both elements can be programmed by anyone with XML knowledge, and applied to the books or libraries in the easier way.
eBook Factory is also capable of exporting graphic files, whether they consist of imported images in Adobe InDesign as if it comes with tables or even groups of lines and boxes made directly on this application.
eBook Factory, unlike the craft approaches, ensures the optimum balance between the resources used for labeling and those required for technical tasks (schemas, XSL, CSS...), providing a considerable saving of time and money over other options. It is, today, the cheapest way to get ebooks from your editorial founds.
