2.1 Documentum Cornerstone
The Content Server forms the heart of Documentum, providing essential services to create, version, manage, and archive content and objects in the Documentum system.
Content Server (earlier known as 'eContent Server') houses a repository, which Documentum terms a 'Docbase', to store the various content and its associated properties (metadata).
Note
Documentum 5.3 Update
Note that Documentum release 5.3 adds some new and improved features in the Content Server, such as support for dynamic groups, i.e. groups whose list of members is to be treated as a list of potential members, and \enhanced object-level permission assignments via ACLs (Access Control Lists).
