Abstract

Systems and techniques to generate a virtual hierarchy for navigating in and between object hierarchies. In general, in one implementation, the technique includes: flagging nodes in one or more object hierarchies as entry points and generating a virtual hierarchy including a virtual root and the nodes flagged as entry points depend directly from the virtual root.
