"Book is updated signal"
Is there a 'book is updated' signal?
I was thinking of a plugin that will check the tags of books and than change them so there will be a minimum of tags.
(e.g. it will change "science fiction" in "genre.science.fiction")
Allthough I can write a plugin that will do this on a click, I was wondering if there is an option to detect changes of metadata.
In that case I can process the new tags at once.
