Abstract: A communication system provides an exchange service between multiple companies. Messages between companies are routed through the exchange. These messages may represent any data or functionality desired by the companies. These messages may be requests, quotes, replies, and similar messages. Certain types of messages are designated as events to the exchange system. A portion of the exchange handles these events with rules, producing actions and additional events in response to occurrences consistent with the rules.

Abstract: A system for service transaction brokering among distributed marketplaces includes a first marketplace (102) that provides at least a first service and a second marketplace (102) that provides at least a second service. The system also includes a service transaction broker (104) that is coupled to the first and second marketplaces (102) and that provides at least the second service of the second marketplace (102) to a user (200) that is coupled to the first marketplace (102) in response to the user (200) communicating a service request.

Abstract: A computer implemented system enables a global user interface. The system includes a plurality of application engines (110, 114) and a user interface process (124). The system also includes a visual information broker (118) that has dynamically loadable adapters (120, 122) where each adapter (120, 122) is appropriate for accessing one of a plurality of types of engines. The visual information broker (118) can thereby interface between an engine interface (112, 116) of an application engine (110, 114) and the user interface process (124) by dynamically loading an adapter (120, 122) appropriate for that type of engine. The computer system also can enable a global messaging bus. The system includes native messaging supported by a network messaging layer (180). A plurality of message bus manager processes (176) each include a dynamically loadable message bus adapter (178) and a message bus application program interface (174).
