• Investigation point:  VISSv2 with MQTT as "transport" - is there a possible compatibility?
• General (MQTT and other):  Binary data representation to optimize compared to VISS-JSON transport.
  • ...use also as variant encoding in VISS?
  • ...use as independent protocol (not part of VISS spec)
• AUTOSAR Adaptive compatibility
  • SOME/IP is important so we cannot ignore it.
  • DDS also.
  • (However, ARA:COM abstracts the technolgies.  For AUTOSAR systems, generating ARA:COM XML format is enough, the rest follows.  For non-AUTOSAR systems that are going to communicate with AUTOSAR systems, however, something that implements the concrete chosen protocol is needed. 
    • Previous work:  Franca IDL → Common API for SOME/IP and vSomeIP, and Franca IDL ↔ AUTOSAR XML converter)
  • Opinion:  SOME/IP is used in a very static way – an alternative might be desirable.
  • (AUTOSAR) RESTful services (not HTTP, rather stateless principle, get, set etc.) → Only discussions currently, no drive?
    • How is this concrete protocol defined?
    • Bosch might be willing to work on this.
• Protobuf conversion → Main page
  (because it is used and preferred by SENSORiS, but is also generally popular, and there was a recent vspec2proto converter proposal in vss-tools)

A lot of communication related technologies were investigated in the Generic Protocol Evaluation project during 2019.
A set of reference links are here : List of relevant technologies
