By name linking
You identify objects using a combination of a namespace and a name, referred to as a fully qualified name. The use of fully qualified names, called by name linking, makes it easy to identify and locate objects, and to correct broken references.
For example, if you rename an object, all references to that object are broken. If you substitute another object with the same name, all the broken references are corrected.
This concept is important when you are working in a team environment. With by name linking, you can share files in a repository and concurrently modify, add, and delete objects in your message flow application. When you integrate the various parts of the message flow application, you can detect and resolve broken references to objects that have been moved, renamed, or deleted.
