The Service Deployment object is a special type of control object that describes how a specific repository will deliver the Service Operations described in a SDef for a class of Data objects described in a CModel. The SDep is note executable code but instead it contains information that tells the Fedora repository how and where to execute the function that the SDep represents. In the CMA, the SDep acts as a deployment object only for the specific repository in which it is ingested; each repository is free to provide functionality in a different way. For example, one Fedora repository may choose to use a Servlet and another may use a SOAP Web service to perform the same function. As another example, individual repository implementations may need to provide the functionality at different end points. Or perhaps, a specific installation may use a dynamic end point resolution mechanism to permit failover to different service providers.
