Advancing a pattern-based approach to allow Web services to disseminate information to one another

Table of Contents


On October 11th 2006 OASIS announced that its members had approved the WS-BaseNotification, WS-BrokeredNotification and WS-Topics specifications as OASIS standards. For more information see the announcement.


The purpose of the Web Services Notification (WSN) TC is to define a set of specifications that standardise the way Web services interact using "Notifications" or "Events". They form the foundation for Event Driven Architectures built using Web services.

These specifications provide a standardized way for a Web service, or other entity, to disseminate information to a set of other Web services, without having to have prior knowledge of these other Web Services. They can be thought of as defining "Publish/Subscribe for Web services".

These specifications have many applications, for example in the arenas of system or device management, or in commercial applications such as electronic trading.

For more information see the TC Charter and FAQ.
