Abstract

A system and method are disclosed for an interactive multimedia file (iMF), running on an interactive multimedia runtime (iMR), to store an object onto a computer, the method comprising creating a local instance of the object, storing the local instance into a memory location on the computer, monitoring changes to one or more data slots of the local instance, assigning a version identifier to the local instance, synchronizing the local instance with a main instance of the object, and interfacing the one or more data slots of the local instance with said iMF during execution.
