What Is the SAS Type Dictionary?

The SAS type dictionary is a set of object type definitions that describe the common and shared objects that are used by SAS applications. A type definition is metadata that is represented in the SAS Metadata Repository by an object of the TypeDefinition metadata type. To determine the object types that are in the SAS type dictionary, view the dictionary in the SAS Folders tree. The type definitions are in the /System/Types folder.
The type definition contains information that is necessary to display and operate on instances of that object type in a SAS application. For example, instead of describing the content of an object (like a table’s columns, indexes, and keys), the type definition defines the icon that is used to represent the object type in a SAS application, the metadata template that is used to retrieve the object’s logical metadata definition, the type of object that should contain the object in the Folders tree (folder or other object), and the classes used to provide copy, paste, move, delete, import, and export functionality for the object.
Note: Not all object types support import and export. And, not all object types appear in the Folders tree.
