Events and service-oriented architecture: The OASIS web services notification specifications

The OASIS Web Services Notification (WSN) family of specifications defines a standard interoperable protocol through which Web services can disseminate events. We present here a summary of three WSN specification documents that are currently available: WS-Base Notification, WS-Topics, and WS-Brokered Notification. We conclude with a brief discussion on the use of the notification pattern in the Enterprise Services Bus, a service-oriented infrastructure for mediating requests among cooperating Web services. © Copyright 2005 by International Business Machines Corporation.
