VSS feeder update: connecting the graphql schema

  • Stefan: was able to put the graphql at work , I have a problem with the docker setup and the simulator that runs outside the VM
    • demo can be shown as first milestone, i.e. at the virtual tech summit workshop
    • Stefan will contact gunnar after
  • Stefan: shows the set up of this demo and explains the problem he has with the nxtworking between the VM and the simulator that runs on windows
  • Philippe: why don't you the GVS (GENIVI Vehicle Simulator) that runs on linux ?
  • Stefan: we should use at a later stage a "better" database like SQL for instance
  • Gunnar: can you all take into account the packaging, like we did in other projects where we use a docker setup ?
  • Alex: I  am fine with the docker packaging

virtual technical meeting - workshop preparation

  • Alex: I had a call with Stefan yesterday, I do not know how deep we need to address the topics, let us do a brief overwiew of the topics
  • topic #1 - VHAL implementation based on the graphQL implementation
    • Google requires OEMs to implement properties in the Google way
    • we want to deliver these properties outside the graphql server
    • I hope to have JLR working on the proof-of-concept implementation with us, then we need to identify which workpackages need to be implemented
    • Philippe: JLR people are shutdown for the month of May and will not show up again until next month, it is a good idea to prepare an updated work breakdown structure
  • topic #2 - permission group
    • Alex: this is about the concept introduced by Gunnar about the VSS layer concept; I would like to have a discussion on which concept we will follow in the future
    • Alex: in our architecture we have different players, player 1 is the app, player 2 is the authentication service that generates the token, player 3 is the dataserver
    • Alex: I intend to present my understanding of what I have learned about permission management
  • topic #3 - graphql schema
    • Alex: I generated the graphql scheima for the GENIVI VSS standard tree (on github)
    • there is a private area for each and every OEM has his own branch
    • do we need an additional layer to be  integrated into the graphql schema ? or do we create empty leaves in our schema ?
    • Gunnar:  we need both actually
    • Alex:  do we talk about the generation process at the workshop ?
    • Gunnar: I would like to invite you, Alex to partiicpate to W3C call on VSS call this evening

introduction to External Data Server proof-of-concept

overview of architectural design options for the Vehicle Data Interface

  • (introduction added offline) Philippe:  the outcome of the February 4-5 F2F meeting is described in this slide deck
    • the team identified 4 options for the Vehicle Data Interface design (and 4 proof-of-concepts that could be implemented for experimenting and validating the design options)
    • the team has set up priorities for the proof-of-concepts implementation, the PoC priorities do not refer to which architecture should be deployed in production, they reflect rather the team preference for which PoC to start implementing first
  • Gunnar shows the following slide deck Vehicle HAL Architectural Design Concepts and explains the design options

VSS feeder proof-of-concept demo

  • Philippe: browses quickly through the slidedeck presented by Stefan two weeks ago
  • Stefan: will resume this week the work suspended because of the Easter break

graphql and nodeJS installation, graphql schema example

  • Alex: will finalize the upload of the graphql schema example and instructions for installing graphql and nodeJS this week after last week's Easter break

virtual tech summit : AASIG VHAL workshop preparation

  • Philippe: we need to start gathering the items for the agenda of the AASIG VHAL workshop and the AASIG VHAL project report at the upcoming virtual technical summit
  • Philippe: the abstract of the workshop is the following (published on the virtual tech summit registration page)

    • "The AASIG VHAL / Vehicle Data APIs project has detailed a delivery roadmap for its initial deliverables.  During a successful face-to-face meeting hosted at the beginning of February by BMW in Munich, the project team identified four proofs-of-concept (coding projects) corresponding to the various software architectural options that have been debated since last November’s GENIVI Technical Summit, held in Troy, Michigan.  The first proof-of-concept implementation is the External Data Server (EDS) proof-of-concept that investigates how to extend Android access to vehicle data. The rationale for this work is that the number of vehicle properties currently defined in standard Android is very limited as compared to the thousands of vehicle-related signals OEMs are considering for their connected vehicles. Although the project could propose to expand the standard vehicle property list in Android, the integration of Android into a complex electrical and connected vehicle architecture suggests a bigger picture to consider.  Standard data access methods should be applied in the entire vehicle and in cloud-connected services.  This EDS proof-of-concept intends to validate the concept of a data server accessing the vehicle dataset as described by VSS (Vehicle Signal Specification standard), which is used also in W3C Automotive Group, and enabling authenticated Android apps to access the vehicle data through a web socket protocol. The actual values of the vehicle signals will be queried/updated thanks to a VSS feeder that will connect to the rest of the vehicle using, for example, Some/IP.

       The AASIG VHAL / Vehicle Data APIs project team will present a status report of the EDS proof-of-concept implementation and explain the design choices made. The following next steps will be then comprehensively debated:

      • External Data Server proof-of-concept versioning w.r.t. roadmap milestones
      • Early assessment of implementation TRL (Technical Readiness Level)
      • Ensure project participants have opened, or are planning, a discussion to achieve synchronization of activities with Google's Android team
      • Other proof-of-concepts implementation"
  • Philippe: will contact Alex offline for the preparation of the sessions

VSS feeder proof-of-concept demo

  • Stefan: shows this slidedeck presenting the analysis and experimentation he made on the VSS feeder of the EDS part of the proof-concept
  • first topic is about using opends as the vehicle simulator to feed the vss feeder
    • code written in nodejs
    • use a naive database written in json
  • Gunnar: the transformation of signals into VSS is done manually in your example, we could make a generic mapping on how to translate from one signal to the VSS tree
  • Stefan: agreed
  • second topic is about using the genivi-vehicle-simulator (GVS) - as the vehicle simulator to feed the vss feeder
    • Stefan: provides a short overview of the simulator
    • Gunnar: did you have trouble compiling the vehicle simulator code
    • Stefan: none
    • Philippe: asks question to Magnus about the simulation of EV vehicle signals in GVS
    • Magnus: will look at how to implement a small model for simulating EV signals in GVS
    • Philippe: explains as a side comment the reason why the GENIVI CCS project is introducing EV signals in the VSS tree: first this is to a state-of-the-art demo showing connected EV data rather connected ICE vehicle data and second this is also an attempt to trigger OEMs on providing inputs on EV data
  • Johan: we are using a different version of opends in W3C, we made some small changes

graphql schema example

  • Alex: shows the graphql schema he is using
  • Alex: reports the issues he had with some VSS descriptions
  • Magnus: we are currently looking at Daniel Wilms' work on include statement in yaml
  • /TODO/ Alex to submit the issues he encountered in the github VSS tracker
  • Magnus: we need to work on some sort of VSS validator to check the syntax
  • Alex and Gunnar will take offline the publishing of the example on the GENIVI github

graphql and nodeJS installation

  • Alex: I have a 1.3 Gbyte image for graphql and nodeJS installation ready
  • Gunnar: can you also provide the docker instructions for building the image ?
  • Alex: yes, Alex and Gunnar will take offline the publishing of these items on the GENIVI github

AOB - virtual tech summit - VHAL workshop moderation

  • Philippe: the AASIG VHAL workshop is scheduled on Wednesday 13 May at 3 to 6pm CET (best US Pacific friendly time we can propose)
  • Philippe: asks Alex and Sachin whether they can be moderators, the workshop agenda preparation will be shared with the team in the upcoming weeks until the tech summit
  • Alex: yes, possible for me
  • Sachin: I will check whether I can participate, will provide feedback in a few days

Friday 27 March March - 200pm CET

Participants

  • Alex, Stefan, Philippe

Agenda

  • authentication service implementation (work sharing between BMW & TietoEVRY)
  • AOB

Minutes

1. BMW has implemented the Service for Authentication:

  • Service written in Kotlin - conclusion: Android buildsystem does not support Kotlin yet - needs to be rewritten if integrated in platform
  • IPC between Service - App done manually - conclusion: can be rewritten to hide boilerplate via AIDL generators
  • JWT kept internally as string with payload: uid + permissions as a List<String>
  • Secretkey to sign JWT shared manually (i.e. no single point of encrypted storage) - Action to be put in the backlog: "Decide and configure storage of secret between Server and Clients")
  • Example permissions exposed in AndroidManifest

2. BWM has implemented the Client application to use Authentication Service:

  • JWT retrieved as bundle - can be reworked for AIDL object
  • Connection to GraphQL not analyzed, but not that relevant for the scope of Authentication Service

3. The code is not shared yet because of process of licensing and OSS check by BMW

4. We had a little session about finding similarities/improvements/possible reusage of https://github.com/GENIVI/aasig_dev_platform/tree/develop/vendor/genivi/modules/vssandroidservice

5. Based on conclusions from point 4, TietoEVRY proposed - since kotlin implementation needs to be rewritten eventually - to provide Java implementation containing:

  • Proper buildsystem support: Android.bp for future platform integration + gradle for development
  • AIDL definition that is more developer friendly and can be easily kept as "compiled" .jar library for 3rd party development of Applications
  • Functionality of Service will be the same as BWM kotlin implementation
  • MPL 2.0 license

Tuesday 24 March - 500pm CET

Participants

Minutes

authentication implementation

  • Alex: I was preempted by internal projects again, although I did some work on graphql

  • Stefan: we need to schedule a meeting

  • Alex: we can have a meeting on Thursday at 10-11:30am CET

  • Stefan: will send an invitation DONE

graphql and nodeJS installation

  • Alex: I need to package what I have done in a container in order to make my work easy to reuse
  • Stefan: can you give us a snapshot of what you have done ?
  • Alex: yes, Alex shows the schema representing the vehicle data he is using for the testing of graphql together with some queries
  • Philippe: it would be good that team participants have a look at the Apollo GraphQL documentation to get more familiar with the approach: https://www.apollographql.com/
  • /TODO/ all participants to look at the Apollo GraphQL documentation: https://www.apollographql.com/

Next week's All Hands call preparation

  • Philippe: I may have to escalate the situation and report that AASIG VHAL team have difficulties to staff the poc
  • (added offline): as in all collaborative projects, it would be good that each participant consider spending a little bit more time than attending the calls and reading the minutes, otherwise everyone gets the impression the work is stuck
  • Stefan: point 13 of the WBS (Define GraphQL schema - what does it look like?) was actually done by Alex as he showed the schema today
  • Alex: agreed, I have the schema but something is still missing
  • Stefan: we need to have something to get started on the other work items
  • Stefan: we need also to agree on the data format
  • discussion follows on how to bootstrap the work
  • Stefan: will work out some prototype code and show it at the next VHAL call
  • Philippe: next week's call will be the AASIG All-Hands call on 31 March at 17:00 CET (watch out: there is a time change scheduled on 28-29 March in Europe)
  • Philippe: next VHAL call will be scheduled on 7 April at 17:00 CET

Tuesday 17 March - 500pm CET

Participants

  • Alex, Sachin, Stefan, Piotr, Johan, Stephen, Gunnar, Philippe

  • AOB

Minutes

authentication implementation

  • Stefan and Alex will clarify their mutual contribution to this topic this week

graphql and nodeJS installation

  • Alex: this is on my todo list for this week

staffing the EDS PoC (again !)

  • Sachin: the people I contacted at Daimler acknowledged my demand for implementtersn, no positive feedback yet,, will continue to ping them
  • then the participants resume the review of the work breakdown and discuss the candidate technologies to implement the components

  • work item #7 - agree on PoC use cases for the implementation

    • Stefan: during the F2F meeting, we said we will use the battery voltage for an EV and also the tyre pressure and air conditioning information

    • All: an EV application is the right app to develop for a demo

      • we will show the battery status and battery consumption during a drive

    • Stefan: Tieto evluated the GENIVI vehicle simulator available in github, this simulator can provide some of the data we needed like the property of speed during a drive
    • Johan: opends used in W3C is also a candidate, link:  https://opends.dfki.de/, configuration files are written in xml,
    • Gunnar: one of these simulators would be the data provider box  in the PoC block-diagram for the use case showing the vehicle speed or other vehicle signals like the tyre pressure and a simple simulation covering the EV signals (alternate data signal feeder) would be used for the demo use case showing the battery status and battery consumption
    • Tieto is analysing the simulation aspects for the PoC
  • work item #9 - Select and implement feeder input API → how feeder writes data into the "shared database"

    • Alex: do we take a database or in-memory hash values ?

    • Gunnar: the feeder is writing the values into the database, this work item is just the interface to the database, whatherver is coming from outside needs to be stored internally

  • work item #10 - VSS data server component - supporting technos

    • Alex: I will add a description on how to install graphql on ubuntu but what about using a virtual box where everything is installed ?

    • Gunnar: it would be ideal to package it that way

    • Stefan: we said we would run it on docker, this is another possible solution

    • Philippe: reminds the demo execution architecture, we will one laptop running the EDS on Linux and for the IVI unit either one laptop running the Android simulator or a target board like R-Car or NXP

    • discussion on the selection of docker vs virtual box

    • *decision* docher is the environment we will use

    • graphql and nodejs will run on docker

  • work item #11 - Implement the connection between the access protocol (GraphQL) and the fetching/writing of data into the database

    • discusison on VSS representation and graphql schema

    • Alex: I have something already and can possibly provide it although it needs some refactoring, I need to check with my management

    • Alex:I  can show what I have done in the next call

  • work item #14

    • this is the graphql query, it corresponds to the implementation of the resolver function in graphql

  • work item #15

    • this work is included in workitem 14 but wiriting, a writing function in graphql is called a mutation function

  • other work items
    • discussion not captured, look at the WBS wiki page
  • discussion on whether we add a column in the WBS table to capture the technologies used before capturing the volunteers' names

Authentication

  • Alex: we are using Apollo graphql server which needs an addition for web token management, and other stuff we are working on, I have discussed which contribution we could do with Markus
  • BMW has the blue box on the right box (authentication) (look at the EDS architecture diagram)
  • BMW has only the EDS implementation, not the Internal Data Server one
  • Alex: the permissions are not yet what we need
  • discussion on the work to do for the authentication and the access control groups
  • Gunnar: we need to do a more formal description of things to be done for the authentication
  • Alex: might be able to do some work in the next days, will try out my ideas on an actual implementation, as soon as I have something (next week possibly), I will generate some docs like ppt
  • Alex: tooling is not clear for me yet, as soon as we agree on the way to specify things, we will talk about tooling and manifest generation
  • discussion on the naming of artefacts
  • Alex: we want to have a nodeJS graphql implementation running
  • Alex: I can describe the nodeJS and graphql installation and the deployment of json files
  • Gunnar: the wiki page for documenting tihs is AASIG: Implementation notes
  • /TODO/ Alex to describe the nodeJS and graphql installation in the above wiki page
  • Stefan: at Alex, since you have the authentication implementation under way, could you spent some time to describe what you have done so that we can identify the leftovers ?
  • Alex: I can explain that, for instance we need a json web token implementation
  • /TODO/ Alex & Stefan to clarify what could be the contribution of BMW & Tieto to the authentication mechanism implementation

Recap on PoC architectural design

  • Alex: presents the so-called External Data Server Proof-of-Concept architecture
    • on the right side, this is the Android Automotive based infotainment unit

    • what we did: we tried to open our mind w.r.t. the abstraction to our bordnet interfaces

    • explains the rationale for the work done

      • point #1 is abstraction

      • point #2 is to bring this into the vehicle, this is where we use VISS (the implementation of VSS)

  • Steven: this seems to me a way to solve the deployment of OEMs / Tiers 1 applications

  • Steven: how do you solve the deployment of third party applications ? will this still use the vehicle HAL and the vehicle properties ?

  • Alex: explains we would like to go to Google with this proposal

  • Steven: will you put the VSS server in the appstore ?

  • Alex: we have not considered it yet
  • Steven: how do you intend to go to Google ?
  • Gunnar: we had contact with Google Automotive team in the past, but people have changed, we intend to reach out to Google through OEMs
  • Andrii: only the access to the data is external to the data server , there is some kind of confusion between internal & external data server architecture in my opinion
  • Stephen: we need to think about the safety domain in the vehicle EE architecture, we might have the data server running on the safety domain
  • Andrii: how do you manager the question of permissions for accessing data when the car stops vs the car moves
  • Alex: there are properties in the VSS and we will define groups with permissions that will be enhanced with the manifest files at application level, the management of these 2 set of datas will be probably handled at application level, but this is to confirm
  • Philippe: shows the PoCs we identified and their priorities
  • Philippe: we need an updated version of Vehicle HAL Architectural Design Concepts presenting the various architectural design options

Call for participation to PoC activities

  • Proposal for organizing a second F2F meeting before EoY, meeting could possibly hosted by Tieto in Poland
  • /TODO/ Gunnar create a duddle to gather the possible meeting dates and then send the date and other requirements for the meeting to Viet-Ahn
  • /TODO/ Gunnar create a wiki page to gather the inputs and outcome of discussion on the architectural design
  • Alex: we need to identify the building blocks in the architecture diagrams
  • Alex: for instance we need to add the authorization / permission scheme stuff, one approach is to reuse Google permission scheme
  • discussion on ServiceIds in Android
  • Stefan: posts the following link: http://androidxref.com/9.0.0_r3/xref/packages/services/Car/service/src/com/android/car/hal/PropertyHalServiceIds.java

  • Sachin: I would recommend that we look for what we are violated from Google ? what contradicts the certification requirements of the CTS ? IMHO we need to have to look at the level of the standardized requirements that the CTS checks

  • Stefan: IMHO we are not violating anything but a way to check it is to look at the Android Compatibility Definition Document:  https://source.android.com/compatibility/cdd

  • Assignment of work items (for the next meeting)

    1. how permission schemes are managed for custom properties, how access control is managed, vendor extension of the permission (assigned to: Stefan)
    2. reviewing the someip identity and access management,  GPRO has already reviewed this, they need to provide their review results to the Vehicle HAL project (assigned to: GPRO participants)
    3. review of the Android Compatibility Definition Document (assigned to: Sachin)
