Overall description

Fiware-Cepheus provides NGSI-compatible gateway level components. This project contains two Spring Boot applications:

  • cepheus-cep: A CEP (Complex Event Processor) engine.
  • cepheus-broker: A light broker (NGSI forwarding-only).

NGSI v1 implementation is provided by the Orange-OpenSource/fiware-ngsi-api library.


The previous name of the project was "EspR4FastData". It was renamed to a more generic name (using the convention of other FIWARE Generic Enablers).
