Please, ANSWER this question AT https://ask.fiware.org/question/1192/is-sth-comet-service-compatible-with-the-ngsi-ld-data-format/
Question:
Is STH-Comet service compatible with the NGSI-LD data format?
Description:
I'm using Orion-LD and of course MongoDB in my work. Can I use STH-Comet to retrieve NGSI-LD data from MongoDB? And how can I do that?
Is it able to POST a subscription to Orion-LD so that STH-Comet will be notified of new values of a specific attribute?
What's more, I just discovered that there is a new service called Cygnus-LD, compatible with NGSI-LD data, but I see (in the documentation example) that it is used in order to persist the NGSI-LD notifications in the PostgreSQL. Is it possible to persist them in MongoDB instead?

As of December 2020, STH-Comet does not service the NGSI-LD interface and is NGSI-v2 only. However Orion-LD has recently been updated with a new backwards compatibility feature that allows it to send subscriptions in NGSI-v2 format.
