| 3 | 3 | QCG-Notification is an open source implementation of the family of WS-Notification standards (Base Notification, Brokered Notification and Topics). It supports the topic-based publish/subscribe pattern for the asynchronous message exchange among Web Services and other involved entities. The main architecture of our system is based on a highly efficient, extended version of the Notification Broker, managing all items participating in notification events. Today, QCG-Notification offers sophisticated notification capabilities, e.g. notification message filtering, push and pull messages delivery, and it was successfully integrated with different communication protocols as well as various Web Services security mechanisms. The modular architecture of QCG-Notification also provides a great opportunity for developers to build new extensions and plugins to meet other specific requirements. |
