Is there any documentation for protocol keyword for configuration?

Hi,       My setup is made of a couple of arduinos which are communicating with a raspberry via nRF24L01 radio modules. The code on the arduinos is generated with thingml. I want the raspberry to be a gateway to my web server that will display data captured from the arduinos' sensors. From the examples found on this repository, I couldn't figure it out how the annotations and protocol keyword work.       Here, I don't understand how is the connection made between the led_service port and the MQTT broker

Thank you

The annotation registry documents (most of) the annotations.
