Overview Components Publications Demonstrations Resources People		Event Manager and Event Driven Architecture Responding to real-time changes and events in a timely manner is an important requirement for adaptive observation and study. An event-driven architecture defines a methodology for designing and implementing applications and systems in which events are transmitted between loosely coupled software components and services. Building applications and systems around an event-driven architecture allows these applications and systems to be constructed in a manner that facilitates more responsiveness, because event-driven systems are, by design, more normalized to unpredictable and asynchronous environments.

The ECID Event Manager uses a publish-subscribe service powered by JMS (Java Messaging Service) with semantics-enhanced messages that use RDF (Resource Description Framework) triples to allow the exchange of contextual information about the event between the event generators and the event consumers Non-scheduled, event-driven collaboration effectively reduces the barrier to collaboration for scientists and engineers and promotes much faster turnaround time for critical environmental events. Real-time updating and modeling is supported by CyberIntegrator to allow event-triggered execution of specific meta-workflows.
