This chapter explains how to edit the various metadata sets used by the Librarian Interface, and is pertinent to anyone who wishes to remove a value from the previous values tree. While it is simple to remove a certain metadata value from a record or records, the value itself still appears in the the value tree. This is a feature, not a bug. Instead the way to remove previously assigned values, or indeed any part of the metadata set including its elements, is via the metadata set editor, available under the Metadata menu.

Also this is a tool used to alter the import profiles, the instructions used to map metadata from files imported into the collection onto existing metadata sets.
