The FIWARE Catalogue currently contains four context brokers:

  • Orion - NGSI-v2 only
  • Orion-LD - mixed NGSI-LD and NGSI-v2 support
  • Scorpio - NGSI-LD only
  • Stellio - NGSI-LD only

Orion-LD is a fork from the original Orion repository and aims to be merged back at some point. It is the only context broker which can service both NGSI-v2 and NGSI-LD.

Scorpio and Stellio are pure NGSI-LD brokers which don't require the compromises of having to serve both syntaxes. Scorpio positions itself as the heavyweight broker, with a strong interest in federations. Stellio is somewhere in the middle between Scorpio and Orion.

All NGSI-LD brokers are trying to align to the ETSI standard, however new features are still being added (the latest ESTI update, the 1.3.1 specification was a couple of months ago). My understanding is that Orion complies with 95% of the 1.2.1 specification (excluding the temporal API). Scorpio is probably higher but some minor differences can be found within payloads

Running an ACID test NGSI-LD Test-Suite returns the following for Scorpio:

Test Suites: 1 failed, 36 passed, 37 total
Tests:       1 failed, 168 passed, 169 total
Snapshots:   0 total
Time:        38.595s

And the following for Orion-LD (where the majority of failed suites are for the optional temporal API which Orion-LD does not support directly)

Test Suites: 8 failed, 29 passed, 37 total
Tests:       22 failed, 147 passed, 169 total
Snapshots:   0 total

The roadmap for Orion-LD can be found here within the GitHub repository.
