# Manage Catalog

The Manage Catalog tab allows you to change the properties of your repository's catalog and various other repository web pages. Here, the primary class and the primary attribute can be changed, and the Object approval, Joins, and The "What's New" features can be toggled on and off. Here also is where you can view the various repostitory web pages and edit your repository's templates.

Note that modifications made from the Manage Catalog area do not change the underlying data model or metadata objects maintained by your repository. They just determine how your repository looks to those who visit your repository's web site or interoperate with your repository. See help documentation on Repository Properties / Data Model Editor for information on editing the data model.
