Defines a named dataset as being a Librarian dataset.
By default, the associated extension for the dataset is the last qualifier in the dataset name. You can globally override all datasets with a specific last qualifier to a specific workstation extension by using the configure global extension overrides item bar. With Librarian, multiple extensions are possible as Librarian keeps information about the member type in its database. You can specify that these various types be associated with various workstation extensions. All of these entries are automatically added to the directory search function, then you may have additional datasets that do not match the search criteria appearing in the list.
Any extensions specified here are automatically added to the configure controlled extensions list.
