All REST requests must contain both the URI (Uniform Resource Identifir) and the Resource parameters. The URI parameter contains the server name and port number to identify a particular resource. The Resource parameter provides the resource to be identified.

An example of the URI parameter:

    http://{servername}:{port}/rest/

Some examples of Resource parameters include:

• {dataClass}/
  
• {dataClass}{key}/
  
• $catalog
  
• $directory
  
• $info

Failing to provide both parameters in the request may result in a 404 Not Found error.
