Abstract: A method and system enter a correction for a previously sent message, determine whether to send a complete corrected message or a message correction specification, and send the selected message to a messaging server. The messaging server receives the message correction specification and a message identifier (ID), and sends the message correction specification and the message ID to a recipient client system if a message with a corresponding message ID has previously been sent to the recipient client system. Then, the recipient client system receives the message correction specification and message ID, retrieves the message with a corresponding message ID from its conversation log, corrects the message, updates the conversation log, and activates an alert to notify a user of an update. If the message has not previously been sent, the messaging server corrects the message and sends the corrected message and the message ID to the recipient client system.

Abstract: The invention provides a method and system for controlling access to semantic web statements. The method comprises the steps of providing a set of semantic web statements in a defined format, and storing the statements in one or more first tables; and constructing a set of access control lists in the defined format, and storing the lists in one or more second tables. Each of the access control lists of the second tables is connected to one or more of the statements of the first tables, and the access control lists are used to enforce access rules to the semantic statements. Preferably, this access is enforced by filtering out web statements that users do not have permission to read, and by returning errors when users attempt to make changes to the semantic statements that the users do not have permission to change.

Abstract: A method, system and computer readable medium for providing an editing mode for a graphical user interface (GUI) is described. A toggle widget is provided to a user of a GUI during execution of the application presenting the GUI. When the user presses the toggle widget, the GUI is placed in an editing mode, whereby the normal functions of all of the widgets of the GUI, except for the toggle widget, are suspended. While in editing mode, the user is allowed to modify the locations of all of the widgets of the GUI, except for the toggle widget. The user subsequently modifies the locations of widgets of the GUI. Then, the user presses the toggle widget again and the GUI is exited from editing mode. Once exited from editing mode, the normal functions of all of the widgets of the GUI are restored and the new locations of the widgets are fixed.

Abstract: A method is provided for responding to a resource request from a requesting user node in a network of user nodes. According to the method, a response to the resource request is received at a first user node of the network, and it is determined (e.g., randomly) whether or not to send the response back to the requesting user node. When it is determined not to send the response to the requesting user node, the response is forwarded to a second user node of the network through a direct connection. When it is determined to send the response to the requesting user node, the response is sent back to the requesting user node. Also provided is a user node for use in a computer network having user nodes that are each connected to other user nodes through direct connections.

Abstract: A method is provided for discovering resources in a network of user nodes.

A client computer then accesses the remote computer to access secure data. The authorization codes of the example embodiment are stored on the authorizing computer and the remote computer and simple look up and comparison is used to validate the authorization code on the remote computer.

Abstract: A method, apparatus, and program product for modifying Resource Description Framework (RDF) statements in a client-server system. The client-server system includes a server on which is stored RDF statements. A service request is assembled at a client connected to the server requesting modifications to an RDF statement stored in the server. The service request is sent from the client to the server, modifying the RDF statement at the server responsive to the service request. A service response is sent from the server to the client indicating if the modification of the RDF statement was successful. The service request may be an Add RDF request, an Update RDF request or a Remove RDF request. The service request and the service response are stored in memory in the client for tracking purposes.

Abstract: A system and method for routing instant messages uses a user presence service to aid a user in determining to send an instant message to an intended recipient based on user availability information. The method also uses a configurable delivery manager that defines, at runtime, a delivery policy to be used to route the instant message to an intended recipient of the message. The delivery policy is based upon a configuration of the delivery manager, a user configuration of the intended recipient, and one or more available delivery mechanisms. The delivery manager is configured by means of an ordered list of one or more available delivery mechanisms. The delivery manager routes the instant message by dispatching the message by selecting sequential delivery mechanisms, in the order of appearance on the ordered list, until the user presence service indicates the intended recipient is available using the selected delivery mechanism.

Abstract: A system, method and computer-readable medium are disclosed for providing support for a non-persistent service. According to a preferred method, a request for a transaction associated with a non-persistent service is received. It is determined whether the transaction can be executed, and a message associated with the request is placed in a queue. If the transaction can be executed, the message is sent to the non-persistent service and removed the message from the queue. Preferably, if the transaction cannot be executed, the message is removed from the queue without being sent to the non-persistent service. Also provided is a web application server that includes a queue for storing a message associated with a request for a transaction associated with a non-persistent service, and an interface for sending the message to the non-persistent service if the web application server can execute the transaction.
