Yes, this is a very useful guideline one sometimes tends to forget. Anyway
in this case the generalized abstract object is useful for handling the
relations between different things - i.e. a text element can be assigned to
a page, or to an author (biography), or to a book (abstract). A page can be
assigned to a rubric, or to an author (extended biography, works list...),
or to a book (review, excerpt...). Therefore I decided to use one
centralized ID and relations handling.
