The Orion Context Broker is the core component of the FIWARE platform, enabling real-time management of context information across smart applications. It implements the NGSI-v2 (and optionally NGSI-LD) standard APIs to support updates, queries, and subscriptions to changes in context data. Orion is typically deployed alongside IoT Agents, databases, and analytic engines to build interoperable, scalable smart systems — including precision agriculture, irrigation control, and livestock monitoring. Developed in C++, Orion is designed for high-performance environments and integrates easily with other FIWARE Generic Enablers.
