Capabilities Of DFS

Runtime Support
        –APIs enable calling of the services from client and execution of services on the server.
Call platform EMC Documentum Services
        –Call ObjectServices.create() to create folder in the repository
Create  new services
       –Create custom functionality not provided by the platform services
       –Adhering to pre defined SOA standards (XML,WSDL,SOAP,WS-Security)
Chain services (Composability)
         –Combine calls to multiple services to create a larger service (composition)
         –Use DFS services in business processes
DFS Location
DFS consumers usually are located separately from the services and call the services via HTTP/SOAP
Java-based DFS consumers can be located inside the same JVM as the services and call the services locally
Local calls avoid the need for DFS to convert Java calls to XML/SOAP
