Documentum 6 new features

Hi,
I have been working on documentum for quite a long time. I have worked on documentum 5.3. Which used web services. Now Documentum 6.0 has support for SOA.
The following are features.
retrieving, updating, and deleting repository objects. Copy and move operations are also available.
Version Control Service: provides operations such as checkin and checkout that concern object versions.
Query Service: provides operations for obtaining data from repositories using ad-hoc queries.
Schema Service: provides operations for examining repository metadata (data dictionary).
Search Service: provides operations concerning full-text and property-based repository searches.
Workflow Service: provides operations that obtain data about workflow process templates and an operation for starting a workflow process instance.
