Systems and/or methods for providing feature-rich proprietary and standards-based triggers via a trigger subsystem

An integration server provided as a component in an application integration system, the integration server comprising a processing system including at least one processor and configured to provide a messaging layer for use across the integration server or an integration server instance, the messaging layer comprising:

• a trigger subsystem including:
• at least one proprietary trigger subsystem embedded therein,
• at least one standards-based trigger subsystem embedded therein, wherein all or substantially all existing capabilities of the at least one standards-based trigger subsystem are embedded in the trigger subsystem, and
• common trigger facilities for the at least one proprietary trigger subsystem and the at least one standards-based trigger subsystem;
• wherein the at least one proprietary trigger subsystem and the at least one standards-based trigger subsystem are provided as parallel subsystems in the trigger subsystem;
• a plurality of parallel trigger layers respectively provided for each said proprietary trigger subsystem and each said standards-based trigger subsystem;
• and,
• a plurality of messaging Application Programming Interface (API) layers respectively provided for each said proprietary trigger subsystem and each said standards-based trigger subsystem,
• wherein each said trigger layer is configured to provide triggers in a format associated with the respective trigger layer,
• wherein the triggers include instructions for causing a process to be executed in or by the application integration system or a component thereof, and
• wherein the trigger subsystem is arranged to enable configuration of the at least one standards-based trigger subsystem free from implementation changes at an application services level.

A method of configuring an application integration system, the method comprising:

• providing a messaging layer for use across an integration server or an integration server instance provided as a component in the application integration system;
• including in the messaging layer a trigger subsystem;
• embedding at least one proprietary trigger subsystem in the trigger subsystem;
• embedding at least one standards-based trigger subsystem in the trigger subsystem;
• configuring the trigger subsystem to provide common trigger facilities for the at least one proprietary trigger subsystem and the at least one standards-based trigger subsystem, wherein all or substantially all existing capabilities of the at least one standards-based trigger subsystem are embedded in the trigger subsystem;
• providing a plurality of trigger layers respectively for each said proprietary trigger subsystem and each said standards-based trigger subsystem;
• and,
• providing a plurality of messaging Application Programming Interface (API) layers respectively for each said proprietary trigger subsystem and each said standards-based trigger subsystem,
• wherein the at least one proprietary trigger subsystem and the at least one standards-based trigger subsystem are provided as parallel subsystems in the trigger subsystem,
• wherein each said trigger layer is configured to provide triggers in a format associated with the respective trigger layer,
• wherein the triggers include instructions for causing a process to be executed in or by the application integration system or a component thereof, and
• wherein the trigger subsystem is arranged to enable configuration of the at least one standards-based trigger subsystem free from implementation changes at an application services level.

A method of operating an application integration system based on a publish-and-subscribe model or a variant of the publish-and-subscribe model, the method comprising:

• providing a messaging layer for use across an integration server or an integration server instance provided as a component in the application integration system, the messaging layer including:
• a trigger subsystem included therein, the trigger subsystem comprising at least one proprietary trigger subsystem embedded therein and at least one standards-based trigger subsystem substantially fully embedded therein, the trigger subsystem being configured to provide common trigger facilities for the at least one proprietary trigger subsystem and the at least one standards-based trigger subsystem, wherein all or substantially all existing capabilities of the at least one standards-based trigger subsystem are embedded in the trigger subsystem and
• a plurality of trigger layers respectively provided for each said proprietary trigger subsystem and each said standards-based trigger subsystem, each said trigger layer being configured to provide triggers in a format associated with the respective trigger layer;
• including in the triggers instructions for establishing subscriptions to publishable document types and for specifying one or more services to process documents received by the subscriptions;
• publishing one or more documents to one or more subscribers in dependence on the instructions included in the corresponding trigger(s);
• and,
• processing each said document in dependence on the instructions included in the corresponding trigger(s),
• wherein the at least one proprietary trigger subsystem and the at least one standards-based trigger subsystem are provided as parallel subsystems in the trigger subsystem, and
• wherein the trigger subsystem is arranged to enable configuration of the at least one standards-based trigger subsystem free from implementation changes at an application services level.
