FIWARE is a curated framework of open source platform components which can be assembled together and with other third-party platform components to accelerate the development of Smart Solutions. The main and only mandatory component of any “Powered by FIWARE” platform or solution is a FIWARE Context Broker Generic Enabler, bringing a cornerstone function in any smart solution: the need to manage context information, enabling to perform updates and bring access to context.

FIWARE NGSI is the API exported by a FIWARE Context Broker, used for the integration of platform components within a “Powered by FIWARE” platform and by applications to update or consume context information. FIWARE NGSI API specifications have evolved over time, currently matching NGSIv2 specifications but evolving to align with the ETSI NGSI-LD standard. The FIWARE Community plays an active role in the evolution of ETSI NGSI-LD specifications which were based on NGSIv2 and commits to deliver compatible open source implementations of the specs.

Building around the FIWARE Context Broker, a rich suite of complementary FIWARE Generic Enablers are available, dealing with the following:


  • Interfacing with the Internet of Things (IoT), Robots and third-party systems, for capturing updates on context information and translating required actuations.
  • Context Data/API management, publication, and monetization, bringing support to usage control and the opportunity to publish and monetize part of managed context data.
  • Processing, analysis, and visualization of context information implementing the expected smart behavior of applications and/or assisting end users in making smart decisions.

FIWARE is not about take it all or nothing. You are not forced to use these complementary FIWARE Generic Enablers but other third platform components to design the hybrid platform of your choice. As long as it uses the FIWARE Context Broker technology to manage context information, your platform can be labeled as “Powered by FIWARE” and solutions build on top as well.

The following sections describe the current list of Generic Enablers of the FIWARE platform structured into five architectural chapters. Before you start setting up your own “Powered by FIWARE” platform, we suggest that you first try developing your first application using FIWARE and also review the FIWARE Tour Guide.

To check out the source code of all of these open source projects and to view the latest test results of the Generic Enablers, go to the catalogue’s GitHub repository.
