Book Part


One organizational unit of a book, typically called a chapter, but possibly also called a part, module, section, unit, topic, volume, etc.


The book-part-type attribute can be used to name the published name of the component for text generation or other purposes, for example:

        <book-part part-type=“chapter”>

As a hierarchical matter, book parts with the title “Part” typically contain other <book-part>s. Book parts with the title “Chapter” typically contain “sections” subunits that are just heads and text, i.e., they have no back matter such as appendices and references. Consequently, if a division of the hierarchical text (in other words, not something “out of line” such as a sidebar) has formal back matter, then it is a <book-part>. The deciding factor is how much metadata you need (sections have only titles, while book parts have a lot of metadata) and whether or not there is formal back matter.
