Hi everyone,within a python application I can easily model object association with simple references, e.g.: ################################################################# class FavoritMovies(object): def __init__(self, movies): self.movies = movies class Movie(object): def __init__(self, name, actor): self.name = name self.actor = actor gladiator = Movie("Gladiator", "Russel Crowe") my_favorit_movies = FavoritMovies([gladiator]) kung_fu_panda = Movie("Kung Fu Panda", "Jack Black") your_favorit_movies = FavoritMovies([gladiator, kung_fu_panda]) ################################################################## So far, so good. But what is best practise to prepare this data for general persistence? It should be usable for serialisation to xml or storing to an RDBMS or ObjectDatabase ... I guess I have to incorporate some kind of id for every object and use this as reference with some kind of look-up dictionary, but I wouldn't like it and hope that there're some other sweet pythonic solutions?

Hi Jan, I guess you're looking for something like the shelve or pickle modules. http://docs.python.org/library/shelve.html http://docs.python.org/library/pickle.html HTH.
