Learn how to update a structured book in Adobe FrameMaker.
Before you update a structured book the first time, each file in the book is represented by an element called <BOOK-COMPONENT>. When you update, the element for each structured file changes to the element of the highest-level element in that file—typically an element such as <topic> or <chapter> that describes the file as a whole. If a file has more than one flow, the element comes from the highest-level element in flow A.
The elements for any unstructured files in the book are still called <BOOK-COMPONENT>. To change <BOOK-COMPONENT> to an element, add structure to the files and then generate and update again.
