I have authored several engineering textbooks. Up to now the author delivers a ready to print pdf to the publisher. Behind the pdf are a graphics program like Adobe Illustrator and writing software like MS Word, Adobe InDesign, or LaTeX. These components are under the full control of the author. He can manage the highly iterative process of creating a good textbook by drafting, checking and correcting, always seeing what later the reader will see.
My questions refer to the case that the publisher introduces XML into his production process of textbooks. 1. What does the author have to supply then? 2. Which software does the author have to use/learn instead of LaTeX (or Word or InDesign) – the output of which may be input for XML? 3. Is there any advantage or relief to be expected from xml from the author's point of view compared to the xml-free way? 4. Does the mentioned quality assuring course of iterative drafting and correcting fit into an XML using publishing process? I would be glad if anyone would respond to my five (see p.s.) questions. If there are weblinks dealing with my concerns please advise. Best wishes
