I guess I would lean toward something halfway between a bunch of reader/writer classes and a database. It seems to me like the scene graph really is the database, but we might need to add a little bit of information to make things more explicit. Named nodes would be the main thing I can think of, so that a scene object could be reused without a great deal of work. If we try to get into the idea of merging nodes I think we can end up breaking things inadvertently. In some scenes an object might seem like a static object most of the time and just need to be dynamic for one thing. Only the creator will know for sure. Optimizations like that can be left up to the program that creates the scene (or the person).

I lean toward doing a protocol for a reader/writer and then implementing the file formats separately without an intermediate format.
