Systems, methods and computer readable media for media for continuous content sharing between systems through intelligent resolution of federated hierarchical graphs are described. A Multi-Topology Middleman (MTM) is used between the source and target systems to handle the content sharing. The MTM builds on traditional import/export infrastructure; it tracks the import/export of individual objects between systems. When a conflict is found between systems, the MTM learns the conflict resolution and stores the conflict resolution as a rule for the conflicting object, and applies the rule for subsequent import/export process on that object. The MTM also tracks the mapping of objects between the source and target systems and updates the target object in accordance with a change in the source object. The MTM is also capable of undoing the import process.
