Classification Group Library
The Classification Group Library serves as a knowledge base for formats that share the same properties. Classification groups can contain a large number of formats, such as all the text formats, or a small number, such as a set of TIFF image formats.
Formats can be assigned to a classification group when they are created. If they are not assigned to a specific group, they are assigned by default to a general classification group. For information on adding new formats, see General Details.

The local Classification Group Library is view-only and cannot be edited by individual institutions. Like the other libraries, it is based on a master global library that a small number of Rosetta users maintain.
