[TYPO3-mvc] m:n:1 relations?

Hey,

To give a indicator on how the models could be arranged, I'd create 4 
models: Book, Person, Role, Relationship (you might find a better name 
for the later).

Now, a Book would have a "relatedPersons" property connected to 
Relationship models. A Relationship would have n:1 properties for Book, 
Person, Role. That way, the same person could have several roles 
(author, publisher, ...) while still beeing a unique entity.
