Relationship between listings (one to many / many to many)

Now we have only a listing without relationship between them . for exemple a software is independent and doesnt related to a company or brand. what could be awesome is to connect all of this and allow realtions. ffor exemple if we do a listing of books and authors (1 author - many books), or a listing of movies (1 movie - multpiple actors / 1 actor - many movies). this would give the last touch of flexibilty of a listing after filters and aloows a huge ranking in SEO beacuse of internal linkings :)here some exemples for listings very usefull that would make great sens and value for a listingBooks and AuthorsOne-to-Many: An author can write multiple books, but a book typically has one primary author.Example: J.K.
