Questions tagged [fiware-cep]

Fiware-cep refers to the PROTON-CEP enabler, a Java implementation of a complex event processor service including rules editor and a proactive event processor as a web service having REST API binding developed as part of the FIWARE platform.

Complex event processing (CEP) consists of high-speed processing of many events across all the layers of an organization, identifying the most meaningful events within the event cloud, analyzing their impact, and taking subsequent action in real time. The PROTON-CEP general enabler of the FIWARE project is the IBM Proactive Technology Online implementation of CEP for that platform, which works as a web service in containers such as Tomcat. Proton is an open source project managed on github and is well documented.
