In some embodiments, a scene definition is modified to generate a modified scene definition based at least in part on a current state of a local database at a device. The modified scene definition is constrained to include references to objects locally available in the local database, and at least one object referenced in the scene definition is substituted with a different object in the modified scene definition that is locally available in the local database. The scene is rendered at the device according to the modified scene definition. ## Claims ### Claim 1 A method for rendering a scene, comprising: receiving a scene definition representing requested source content, wherein the scene definition comprises object references but not object definitions;
