摘要： 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.

摘要： The present invention is directed to a method and system for storing and managing objects, such as binary large objects (blobs) in a digital library system which includes a plurality of clients, an object server for storing an object, a cache server for storing a copy of the object, and a centralized server for storing information identifying the object as being stored in the object server and associating one or more of the clients with the cache server, in which one of the clients, as a requesting client, requests retrieval of an object, a copy of the requested object is sent from the cache server to the requesting client if the object is stored in said cache server, and a copy of said object is sent from the object server to said requesting client if the object is not stored in the cache server; and a copy of the requested object is sent from the object server to the cache server after the object server sends the object to the client, in which the object sent to the client is made available to the client regardless of whether sending of the copy of the object to the cache server is completed.

摘要： A method to generate an SQL sub-expression that implement access control rules stored in a library server. The SQL sub-expression is then merged with the SQL passed from an application program interface (API). The access control checking mechanism is implemented on the server side of the content management system. In this client/server environment, the query SQL statement is built in two layers: the API (client) layer and the server layer. The API sends the query string to the underlying stored procedure. The stored procedure then generates the access control logic based on the configuration parameters of the library server. This access control logic is dynamically added to the query string sent by the API. The stored procedure prepares, builds and executes this new query string as a dynamic SQL statement.

摘要： A content management system is provided including a server computer and a client computer. The server includes a data repository and a stored procedure. The disclosed methodology provides a way of handling parameter passing of structured data for stored procedures in the system. The system is capable of both encoding data into a structured data format and decoding data from the structured data format. The structured data format employs a binary large object (BLOB) and character large object (CLOB) to achieve handling of fixed length binary data and variable length character data. Advantageously, the stored procedure interface need not be rewritten and customized for each stored procedure in the server.

摘要： 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.

摘要： A method of controlling access in a content management system includes defining a domain among a plurality of domains for the content management system and designating a domain administrator for the domain. This enables the domain administrator to perform administrative tasks within the domain without revealing or affecting information in other domains of the content management system. For example, a domain administrator can view user information only for users associated with that domain. The domain administrator also can associate a user with only the defined domain, thereby limiting the user's access to information in the system to information associated with the domain.

摘要： A system, and program product for managing the creation, retrieval, editing or distribution of content by creating a folder and filing the folder in a library on a selected server. This is accomplished by first creating an autofoldering configuration entry in an Auto Link table. Accomplishment of this step results in returning target item types and an auto folder structure. This auto folder structure contains target and source item type IDs. The next step is fetching a next set of target item type attribute IDs, and looping through item types from the auto folder structure, searching for a target folder for each target item type from the auto folder structure. A link is invoked to a folder for each target item found; and a target folder is created if no target folders are found.

摘要： Methods, systems, and program products for managing multimedia content. These are built upon a combination of a high level content model for specific multimedia content types and a low level physical for mapping to a data engine. The method, system, and program product include representing multimedia content management objects and managing the objects in a relational database. The relational database is adapted for representing data in a plurality of relational database tables, where each of the relational database tables has at least one row with a plurality of columns. Content is managed by associating the object as an item to a row in a first relational database table; and associating additional components, if any, of the object to additional relational database tables.
