A system and method for authorizing access to a controlled entity by a user. A set of user privileges is provided for user; and a content manager intersects an access control list (ACL) and the set of user privileges to authorize access. Binding level control indicia selectively binds an access control list (ACL) to the controlled entity at item type, item, mixed, or library binding level. An item type comprises one or more component items with each component item having one or more item views which together form an item type view. A content manager is responsive to the binding level to perform ACL checking for authorizing access to the controlled entity by the user.

System and method for configurable binding of access control lists in a content management system

A content management system provides versioning capability that can either be controlled by the client application or be transparent thereto. Control of document versions depends on the root and child component attributes that are defined by the hierarchical structure of the document. When a document is updated, the present system performs any or all of the following scenarios as desired by the user: replace the existing attribute values stored in the root component instance for a specified document; replace the existing attribute values stored in a specified child component instance for the specified document; add a new child component instance into the hierarchical structure for the specified document; or delete an existing child component instance from the hierarchical structure for the specified document.

System and method for item versioning in a content mangement system

A content management system is provided including a plurality of tables forming a tree-based storage hierarchy. The system includes a library server having a stored procedure which creates a hierarchical tree-based storage structure having any number of child components horizontally and any number of component types vertically thus specifying a tree topology. Advantageously, a single invocation of the stored procedure will create the specified tree-based data storage structure which is stored in the library server.

Content management system and methodology for implementing a complex object using nested/recursive structures

A content management system is provided including a plurality of tables forming a tree-based storage hierarchy. The system includes a stored procedure which enables information to be retrieved from different arbitrary locations throughout the storage hierarchy. Advantageously, the system retrieves information from both simple and complex tree-based storage hierarchies.

Content management system and methodology employing a tree-based table hierarchy featuring arbitrary information retrieval from different locations in the hierarchy

A content management system is provided including a plurality of tables forming a tree-based hierarchy for storing information such as item information. An information retrieval interface is provided to facilitate retrieval of information from the tree-based table hierarchy. The number of cursors employed for retrieving information is dynamically variable with the number of tables in the hierarchy. Advantageously, the content management system permits tables to be added or appended to the initial tree-based table hierarchy after the database is created. The number of cursors is dynamically varied to accommodate the additional cursors needed to query the additional table or tables.
