With FIWARE, cities can achieve the smart city concept with minimum effort but great impact, by adopting common standard APIs and information model
* The Orion Context Broker is its core component. Selected in 2018 by the European Commission as a Connecting Europe Facility (CEF) Building Block, it gathers, manages and provides access to context information coming from different sources describing what is going on in a city.
Orion Context Broker allows you to manage the entire lifecycle of context information including updates, queries, registrations and subscriptions. It is an NGSIv2 server implementation to manage context information and its availability. Using the Orion Context Broker, you are able to create context elements and manage them through updates and queries. In addition, you can subscribe to context information so when some condition occurs (e.g. the context elements have changed) you receive a notification. These usage scenarios and the Orion Context Broker features are described in this documentation.
