Wednesday,  March 4 - Communication Framework

Agenda:

• PoC implementation
• how to instantiate the big picture on different vehicle EE / Cloud architectures
• AOB

Participants

• Gerald (partial), Ulf, Kevin Valdek, Eex (Saferide), Gunnar, Philippe

Minutes

PoC implementation

• Ulf: would like to advertize the prototype Gen2 server implementation we do for the W3C group

• Kevin: supports the proposal

• Ulf: it is not production level but there is a considerable number of functionalities available

• Ulf: error handling is not so resilient yet

• Gunnar: agreed, we need to put this into the blue boxes of the big picture diagram, blue boxes named data server could be implemented using the Gen2 prototype

• Gunnar: graphql is another option that could be demonstrated in a parallel thread

• Philippe: VHAL team is looking at graphql implementation

• Gunnar: this is an argumen tor CCS to look into Gen2

• Gunnar: what about the clients ?

• Ulf: we have small clients available for testing the data servers, Sanjeev (former Samsung) is working on clients

• /TODO/ Philippe contact Sanjeev

• Ulf: would be good to collaborate with the W3C project implementing the data lake

• Phil: would be good to augment the big picture diagram (look at diagram V2 in Vehicle data exchange protocols) with the list of work items and technos used and create a table listing the wok items and the assignees like we did
  to contributors

• /TODO/ Kevin to add link to possible technologies on the diagram

• Ulf: we can use for instance https://github.com/MEAE-GOT/W3C_VehicleSignalInterfaceImpl

• /TODO/ Gunnar do the same

  • Jira

    created
  • Kevin: we need to determine what we use on the OEM cloud part

• discussion on the use of Gen2

• Gunnar: let determine who will provide the graphql implementation , maybe BMW maybe myself (I have to put some work into it)

• discussion on how to align the CCS PoC project and the W3C Gen2 implementation

• Gunnar: we all agree to align projects, what we need are resources

• Rex: I have a common terminology question, which translation / transformation are you talking about ?

• Ulf: BMW has a large number of cars connected today, they do not use VSS format, they use different proprietary data formats

• Ulf: BMW took the decision that once these data are in the cloud, BMW will create the data lake using VSS1 or VSS2 and use graphql to do queries

• Rex: wonders whether BMW is using the ASAM standard for describing signals

• Rex: how is the topic of data compression approach ?

• Gunnar: it could typically be done at the transport protocol level

• Gunnar: what do you, Rex, mean by analyzing compressed data ? we have not touched this yet

• Gunnar: do we need to start looking into OpenID ?

• /TODO/ Kevin initiate the WBS table for the CCS PoC from the example provided here by the VHAL project
