Hi Malisa, thanks for the answer. I am happy to read that there is a shared concern about reuse. My concern is the communication between joining node and central node. Did I understand correctly that you propose to use oscoap for the communication between joning node and central node? what content-formats do you propose to transport between joining node and central node? Will those be different in phase 1 and 2? What contents do you propose to transport? certificates, YANG/CBOR documents, keys? How should I see the co-existence between phase 1 and phase 2? Will phase 2 be an extension of the transported contents of phase 1? Apologies for the naivety of my questions, but the number of discussed possibilities at this moment are quite overwhelming. I just like to get clear how the bootstrap can be composed of different standardized parts and where the future evolution is. Identifying and describing those parts will be a nice step forward.
