Maybe this is to model the cases that have several classifications. For
D is Document "Les travailleurs de la Mer" (of Victor Hugo)
F_hugo is Folder "Victor Hugo's books"
F_h is Folder "Authors whose name begins with a H"
F_guern is Folder "Authors that lived in Guernesey"
F_sea is Folder "Books about the sea"
D filed_under F_hugo
D filed_under F_sea
F_hugo filed_under F_h
F_hugo filed_under F_guern
Therefore, the document D is filed_under 2 different folders, and the
folder F_hugo is also filed_under 2 different folders.
But I believe one of the CubicWeb mentors will have a better answer.
