  • Apparatus and method for document synchronization
    Patent number: 8099663
    Abstract: A computer readable storage medium includes executable instructions to convert a destination document into a destination document tree hierarchy. The destination document tree hierarchy is flattened into a destination document hash table comprising a set of destination document keys and a set of destination document values. A source document is converted into a source document tree hierarchy. The source document tree hierarchy is flattened into a source document hash table comprising a set of source document key-value pairs. A source document key-value pair comprising a key and a value is identified, where the key is not in the set of destination document keys. The source document key-value is added to a changelist. A destination document key is identified, where the destination document key is not a key in a key-value pair in the set of source document key-value pairs. The destination document key is added to the changelist.
