coraine

A lightweight NGSI-LD Context Broker written in C, fully implementing ETSI GS CIM 009 v1.9.1 and passing the official ETSI NGSI-LD conformance test suite.^*

coraine is small — a 967 KiB stripped binary that starts in 10 milliseconds — and plugin-driven: the storage backend, the temporal history, the extra API surfaces and (next) the wire protocol itself are shared libraries chosen at startup. The core broker speaks NGSI-LD; the plugins decide where data lives, what extra endpoints exist, and how the broker talks to the world.

^* The conformance runs use a corrected fork of the ETSI suite. The changes are test-side fixes — the suite has bugs of its own and parts of it do not run as published — never relaxations of what the broker must do. They are filed upstream.
