title: How to open an existing .mom file, or is there any way to see the structure of an existing .mom file
body: <p>I've downloaded a copy of iOS source code and there is a .mom file in the bundle. I just know it is a "product" of NSManagedObjectModel. I wonder is there any way that I can explore the entities in the file, or is there any code snippet to parse its structure. Thank you!</p>
