I am developing an application that could have a potential companion reference in the form of an ePub/PDF/iBook. There's a scheme for opening iBooks from your application, but is there a known way to open a specific book (not import the book, rather open an existing book in the app)? Bonus points: open a specific location in the given ePub/PDF/iBook?
I have scoured Google looking for this answer but only turn up the scheme: only one piece of the puzzle.
