Schema Definition

The directory schema is a set of rules that defines how the data can be stored in the
directory. The data is stored in the form of directory entries. Each entry is a set of
attributes and their values. Each entry must have an object class. The object class
specifies the kind of object the entry describes and defines the set of attributes it
contains.The schema defines the type of entries allowed, their attribute structure
and the syntax of the attributes.The schema can be modified and extended if it does
not meet your required needs.
To find detailed information about object classes, attributes, and how the Netscape
Directory Server (Directory Server) uses the schema, please refer to the
Directory Server Deployment Guide.
