“A content management system must manage the relationships of the information objects it contains. There are two ways to relate information objects: linking and naming. Linking creates a specific connection between two (or more) specific information objects. Naming clarifies the names of things referred to in one information object in such a way that it is possible at a later time to create a link to many different objects.”
