Abstract

Techniques for displaying information related to collection hierarchies. In one embodiment, an integrated direct-manipulation image-based interface is provided for displaying information related to collections. The interface also enables operations to be performed on collections and their elements. Multiple levels of the collection hierarchy are made visible and editable at the same time by the user interface.
