摘要：A system and method of the present invention allow users to access, manage,and edit information about content data, often referred to as metadata. Metadata iscollected from various sources, added, and maintained in a metadata database (232). Inaddition, metadata is dynamically read from the metadata database (232) and dynamicallydisplayed in a graphical user interface (220) in an organized manner, such as a hierarchicaltree. In the graphical user interface (220), a user may add (218), delete (216), and/ormodify the metadata (216). As the user changes the metadata, the metadata database(232) is updated and the user's changes are propagated throughout the graphical userinterface (220) such that the hierarchical tree displays the changed metadata.
