1. A processing device comprising:
memory; and
a processor configured to perform operations stored in the memory to:
generate a base hierarchy tree representing a first object comprising data;
store the data representing the first object in the memory;
generate a second hierarchy tree representing a second object comprising shared data of the base hierarchy tree and the second hierarchy tree and difference data;
store the difference data in the memory without storing the shared data; and
generate an overlay hierarchy tree comprising the shared data, the difference data, and indication information indicating nodes of the overlay hierarchy tree that comprise the difference data.
