Abstract: Provided is a method, system, and program for executing a workflow. A workflow class implement methods and objects to provide information on and control of workflows. A work list class implements methods and objects to provide information on and manipulate work items assigned to the workflows. A work item class implements methods and objects to provide information on and manipulate work items when executing one workflow.

Abstract: Provided is a method, system, and program for generating a workflow. A plurality of graphical user interfaces (GUT) panels are displayed through which a user may define nodes of a workflow and associate at least one action and user with each node. During workflow execution of each node, the associated user performs the associated action. Further, multiple nodes define actions that process at least one object that is routed through multiple nodes of the workflow. A workflow model is generated from information entered into the GUI panels including the nodes and workflow defined by the user through the GUI panels that process the at least one object. The workflow model is transformed into a workflow definition language (WDL) file. The WDL file is then transferred to a workflow server, wherein the workflow server interacts with a database to implement the workflow model defined in the WDL file in the database.

Abstract: Provided is a method, system, and program for performing an Input/Output (I/O) operation on an object during execution of a workflow comprised of nodes. A plurality of objects are stored in one of multiple data stores, wherein each object is identified within the data store with a first object identifier. A workflow packet references at least one object with a second object identifier, wherein the second object identifier indicates one of the data stores and the first object identifier of the referenced object in the data store. An I/O request for one target object referenced by one second object identifier in the workflow packet is received from one node. A determination is made from the second object identifier for the target object the data store and the first object identifier of the target object. The I/O request is performed on the target object at the determined first object identifier in the determined data store.

Abstract: An architecture to enable search gateways as part of a federated search supports searching for data in one or more heterogeneous data sources. The one or more heterogeneous data sources are within a computer system. Initially, a request for data is received at a federated data source. From the federated data source, data is retrieved from one or more of one or more terminal data repositories or one or more search gateway data sources.

Abstract: A method, apparatus, and article of manufacture for an object-oriented framework for managing access control in a multimedia database connected to a computer is provided. A datastore access control object is generated for the datastore, wherein the datastore access control object enables controlling access to the datastore. An access control list object is manipulated with the datastore access control object to set access privileges.

Abstract: A method, apparatus, and article of manufacture for a computer-implemented access control system. The access control system controls access by users to functions of an application program executed by a computer and connected to a multimedia datastore. Application privileges are defined to control access to functions of the application program which operate upon data items of the multimedia datastore. For the application program, one or more users are associated with one or more application privileges. Access by users to functions of the application program is restricted depending upon whether the user has been associated with the application privilege for the function. If the user has been associated with the application privilege, access to the function is granted, if not, access to the function is denied.

Abstract: In one example given, a query for identifying interrelationships between image objects of a set of image objects is received from an input device. Each of a plurality of similarity values between all image objects of the set is compared with threshold criteria from the query. Clusters of image object identifiers are generated based on comparing and are visually displayed on a visual output device.

Abstract: A method, apparatus, and article of manufacture for a computer-implemented workflow agent. Items stored in a data store connected to a computer are tracked in the computer. Initially, a workflow agent is invoked Under control of the workflow agent, an item in the multi-media data store is monitored to determine whether the item meets one or more specified conditions. When the monitoring indicates that the item meets the one or more specified conditions, under control of the workflow agent, whether an action is to be performed is determined. When it is determined that an action is to be performed, the action is performed.
