24th April 2024

Agenda:

  • AMM feedback
  • Team backlog


Minutes:

  • AMM
    • Feedback
      • Paul: Digital.auto came up a few times. Uncertain about what relationship to playground
        • Steve: Personally I see the core digital.auto functionality as being the visual ideation. For that part it could be both a data feeder of VSS data to the playground and a client which uses the playground as a source.
      • Swen: was useful as first time attendee. From CVI discussion yesterday will be sharing mental model of what I perceive as the bigger picture. We need to understand each other to design the right architecture.
      • Haonan: good conference. Good to meet people finally.
      • Steve: Had some interesting conversations in the Showcase with the Playground demo. Some people really got the concept and even talked about using it in their upcoming hackathon. Also had interest from an academic.
    • Thursday workshop
      • Whiteboard:

Image Added

  • Backlog

          • Connections to COVESA eco-system, e.g. CVI southbound, AOSP northbound
          • Embedded App DB (Realm)
          • DIKW Knowledge layer connector
          • Auto h/w deployment (mid term)
          • Complete project setup: release process etc
  • Discussion in meeting:
    • Need data sets (at rest):
      • VSS data sets (real or simulated)
      • Other data models and rule sets.
    • Next week or two Steve will do some documentation polishing and publish the RemotiveLabs bridge sample code as an example (source is available in his github so ask if you want to know sooner)
    • Discussion of knowledge layer
      • Christian/Haonan are continuing to work on the connector
      • Discussion of rules example Haonan posted to the slack.
      • She explained she's currently bypassing some steps in the processing chain, but is just directly looking at the applicability of processing the timeseries data in RDFox to confirm approaches.

28th February 2024

Agenda:

  • Spring AMM sessions
  • Central Data Service Playground
    • Status reports
      • Upstreaming Apache IoTDB support into WAII VISS Data Server
      • Apache IoTDB runtime configuration support
      • Online documentation
    • Continue discussion of Knowledge Layer Connector. One related aspect is the topic of schemas on the data layer side.
    • Roadmap/backlog/work package definition. What does AMM release look like?
    • Feeders
  • AoB

Minutes:

  • Central Data Service Playground
    • Status reports
      • Online documentation: Steve has merged Ulf's online documentation PR to add the Hugo setup. Next step is enabling the workflow to automatically build and publish any content.
      • Apache IoTDB state storage: Steve has added runtime configuration (where to find DB, what database path to use etc) support for the WAII IoTDB connector. It's available in his PR https://github.com/COVESA/cdsp/pull/20. He will send a PR upstream to WAII once its moved to its new home.
      • Realm state storage:
        • Arnaldo had questions about how best to handle the paradigm difference between the typically complex documentation schema used in Realm and the key/value pair schema of VISS/WAII. A second challenge is Realm has C++, but no Go client/binding so how best to interface to WAII get/set methods in Go?
        • Discussion about possible approaches:
          • Complex schema
            • Steve: Same problem exists I think for the JSON-schema to RDF connector for the knowledge layer. We've started with simple with key/value pairs in the store for maximum flexibility, but approaches will need to be found for more complex schema as we go along.
            • Swen: I saw this problem when working with Realm cases. We added accessor methods to our solutions to allow interfacing to other systems.
            • Discussion wondering how BMW VISS implementation had addressed the same issue. Arnaldo/Haonan could look for internal suggestions.
          • WAII connector
            • Steve showed the three WAII methods to be supported (init, get, set) which have straight forward parameters.
            • Two ideas suggested:
              • Use Go binding to other languages. Ulf had succesfully used a package that provided type conversions and binding for C.
              • If Realm has IPC support then it could be used form the Go methods. Ulf explains the Redis connector uses a unix socket.
      • Out of time to discuss Knowledge Layer Connector this week.

21st February 2024

Agenda:

  1. Spring AMM sessions
  2. Central Data Service Playground
    1. Status reports
    2. Upstreaming Apache IoTDB support into WAII VISS Data Server
    3. Continue discussion of Knowledge Layer Connector. One related aspect is the topic of schemas on the data layer side.

  3. AoB


Minutes:

  • Spring AMM sessions: Paul would like any updates. Currently abstracts are missing.
  • Central Data Service Playground
    • Status reports
      • Apache IoTDB support
        • Steve created PR #110 in WAII upstream to add the Apache IoTDB support into WAII VISS Data Server. This was merged by the maintainers. Need to add documentation.
        • Steve also created Playground PR #20 to make it available in a WAII fork. Now changes are upstreamed this can be changed to update submodule to the upstream instead.
      • Realm support: No update this week
      • Online documentation
        • Hugo changes were merged but an issue was found in the signoff. Now updated, this will be merged again this week.
    • Knowledge Layer Connector
      • Some background noise on Haonan's end hampered discussion somewhat.
      • Haonan talked about generators to and from SHACL.
      • Work needed to understand how to connect existing tool, which uses web socket as transport and JSON-schema for message, to the VSS State Storage.
      • Some discussion of schemas in state storage. Danger is becoming bog downed in system design discussions of for example VSS tree vs graph. For know the KISS of VSS key/value pairs is beneficial in its flexibility.
    • In coming weeks we need to consider roadmap/backlog/work package definition, in part so we know what we want to say at the AMM.
    • Steve outlined eco-system discussions related to EU Horizon and with Volvo/RemotiveLabs related to feeders.
  • AoB
    • Paul mentions the work on Covesa website related to project descriptions. Data Arch will need to check their entries.

    1. (Ulf): WAII update


Minutes:

  • Spring AMM sessions
    • Steve has added an outline for the three Playground sessions to the planning page.
    • Agreement in meeting to propose those as placeholders in Paul's planning
    • Ulf will add some sessions on his WAII work
  • Playground
    • Decision taken to merge Steve's PR to give the project master branch some structure. This will make it easier for others to parallel work.
    • Status
      • Adding Realm: Arnaldo says he has the C++ process written to act as a Realm instance orchestrator
      • Adding IoTDB: Steve is working on connecting WAII to IoTDB using the IoTDB Golang client.
    • Christian presents his initial thoughts overlaying the work BMW have presented in recent AMMs onto the Playground
      • Christian Proposal.pptx
      • General agreement that additional viewpoints are needed to logical and implementation in presenting the Playground and that shared diagrams are useful.

      • Christian will be taking some time off in coming weeks but is hoping Haonan can substitute as she is very familiar with the RDF converter.
    • Open decision: need to agree how to handle WAII changes. Upstream, fork for git submodule or git subtree for example?
  • AoB
    • Ran out of time. Ulf prefers to defer WAII update to next time.


17th January 2024

10th January 2024

Agenda:

  • Central Data Service Playground
  • Database abstraction and feeders
  • AoB
    • Ulf has WAII update

Minutes:

  • WAII update from Ulf
    • VISS specification contains consent meta-data mechanism in addition to security control. This consent mechanism is now implemented in WAII.
    • PoC demo of WAII consent together with AIDEN consent framework at Spring AMM. Ulf intends also to present.
    • Work continuing on new feeder architecture he presented in Detroit. He also intends to present update at AMM.
  • Central Data Service Playground
    • Steve outlined status:
      • Been working with WAII maintainers to work through some some issues in upsteam documentation and docker configuration. Thanks to them for support.
      • Steve PR has a basic (incomplete) Playground docker deployment that now works.
      • Apache IoTDB is running as VSS Data Store. Can execute IoTDB CLI client in IoTDB container and communicate with the server.
      • WAII is running as VISS Data Server. Can execute WAII javascript HTML client in WAII container and communicate with the server.
      • Steve did live demo of above.
    • Realm
      • Arnaldo still planning to create a runtime app that can act as admin process for a Realm DB based backend.
      • He asks if C++ is best fit for client API?
      • Initial discussion suggests it would be. Other SDK options in Realm are orientated towards mobile development.
      • Christian makes good point that Flutter support would be useful for reusing the existing BMW code and supporting the mobile/cloud deployment.
        • Christian needed to drop 30 mins in. Follow up on discussion of adopting existing BMW code to Playground required.
    • Arnaldo suggests side meeting with Steve to accelerate his work.
      • Steve happy to meet.
      • Christian would also like to attend such a meeting so he can get up to speed. Early next week (post CES) best for him.
      • Steve will send invite. Arnaldo would like meeting Friday.
    • DB abstraction / feeders
      • Steve reports he has looked at kuksa CAN provider and thinks it could be interfaced.
      • Discussion of possible DB abstraction
        • Steve: is there something we can do to encourage more joint work on feeders by making it easier to interface them northbound.
        • Gunnar suggests doing some native code to see if there is similarity

3rd January 2024

  • Small scale meeting kicking off new year.

13th December 2023

Agenda:

  • Central Data Service Playground: progress, roadmap
  • End of year holidays: When to end and restart?

Minutes:

  • Apologies: Ulf, Christian
  • Central Data Service Playground
    • Progress: Steve reports some problems were found with WAII Docker support, but now addressed. Now working on IoTDB. Currently blocked by runtime issue. Asked for input upstream. We will not achieve the hope of having the base Docker up by 2023 work stop. Will need to push on with that at start of 2024.
    • Roadmap
      • Covesa Board and officers are looking to build roadmaps early in 2024 for strategic development. Playground will be part of that. Suggest we get the Phase 1 PoC working asap in 2024, then use the review of that both to define Phase 2 as planned, but also seed the ideas for this Roadmap request.
  • End of year holidays:
    • Richard informs GM will be finishing next week as well.
    • No meeting Weds 20th and 27th of December.
    • In 2024 do we restart on Weds 3rd or 10th of Jan? As 10th will be CES and many people will be there decision to restart on 3rd for those who can make it.

6th December 2023

Agenda:

  • Central Data Service Playground
  • Autosar Vehicle API
  • BMW Knowledge Layer paper
  • AoB
    • End of year holidays

Minutes:

  • Apologies: Humza, Arnaldo
  • Steve summarised the status update given by Autosar Cloud WG earlier this work on their work on Autosar Vehicle API.
    • Good work done on Autosar to VSS conversion.
    • Current concept is focused more on translation, with greater freedom on northbound protocol compared to the API Gateway concept they expressed before project setup. They are looking at VISS northbound for instance.
    • Look at the Cloud WG artifacts (Autosar membership required) for details.
  • Christian gave an explanation of the Knowledge Layer paper that he mentioned previously that BMW were working on and is now published.
    • Paper: https://www.scitepress.org/Documents/2023/122550/
    • Discussion of split between "query" front end language and data layer connector in backend providing data. In current implementation there is not a GraphQL Resolver style fetcher that could be connected to a DB. Instead the data schema is directly synched to the app logic.
  • Central Data Service Playground
    • Steve gave quick intro to Christian on source structure.
    • Further changes pushed since last week including fuller docker compose for the Playground with Apache IoTDB backend. To make changes more visible Steve has created a WIP PR in the Covesa git rep https://github.com/COVESA/cdsp/pull/16
    • Christian has some ideas about using the Playground for Knowledge layer experiments. Will talk to Daniel about these and come back later.
    • Humza reported offline that MongoDB will look at Realm backend next week.
  • End of year holidays
    • Christian: will finish around middle of wk 51 (week before xmas) and back wk 2 in '24.

    • Paul reminds about the sync call with the Autosar Cloud WG Thursday. Brief discussion about their use of VISS. Need to hear what they have to say to progress.

22nd November 2023

Agenda:


Minutes:

  • Central Data Service Playground
    • MongoDB can only attend first 30 mins, so state storage discussion split into two 30 mins slots.
    • 1st 30 mins (all)
      • Paul asked about peoples perceptions of production readiness.
      • Ulf began description of WAII storage implementation
    • 2nd 30 mins (UIf, Humza, Arnaldo, Steve)
      • Ulf completed description
      • MongoDB asked Qs.
      • Some important notes
        • Ulf has changed implementation on Master branch so Set writes directly to feeder for latency reasons
        • CCS State Storage github is just an example. It is not consumed by WAII and therefore WAII Service Manager implementation is in focus.
      • Out of time. Continue discussion in Slack.
      • Ulf on holiday next two days.
      • Humza/Arnaldo busy with show next week. Following week they will look at Realm implementation.

15th November 2023

Agenda:

  • Playground big picture: Continue discussion of what/why/how
  • Tasks towards the creation of the Playground PoC
  • Playground use cases both for us and externally
  • Spring AMM


Minutes:

  • Big picture
    • Ulf: interested in helping with WAII/VISS parts. The Realm Sync work between MongoDB and BMW would be an interesting feature to add.
    • Discussion of WAII State Storage abstraction and future possibilities.
      • Ulf: Current implementation reflects needs of the VISS protocol.
      • Whilst it will not allow you access to full performance of the DBs its agreed that as a first step it makes sense to integrate to the current abstraction. Then consider internals to meet additional requirements as follow up work.
      • Realm is an application DB rather than a standalone service. Discussion of creating a thin Shim or Connector application to interface Realm to WAII State Storage abstraction.
      • Christian: Future work on the northbound state storage abstraction would be interesting topic.
  • Tasks for creation of Phase 1 PoC
    • State Storage integration
      • See above for discussion on Realm
      • A side meeting will be arranged for interested parties to discuss. Steve will post on slack.
    • Steve outlines thoughts he had for source repository structure:
      • Source of Central Data Service Playground itself
        • Docker
          • DockerFile for image
          • docker-compose spinning up image
        • Yocto, SOA etc.
      • Doc
        • Playground (What, Why, How, Best Practices), Connections to other components, Dev, Use Cases etc.
      • Scripts
      • Diagrams
      • Use Cases and examples (e.g. docker-compose collection for docker deployment)
        • hello-world
        • Christian's case
        • Sync
        • etc.
  • Use cases and use outside the group
    • Discussion of using docker-compose to organise use-case examples.
    • Discussion of possible uses of the playground within Covesa.

8th November 2023

Minutes:

  • Central Data Service Playground
    • Steve summarised the work over the last week.
      • Main task tickets are now done for the Phase 1 PoC. In big picture terms main missing areas are testing and use cases.
    • Caught Christian/Humza/Arnaldo up on last weeks discussions
    • Use Cases
      • Christian posted an idea as input to slack and will add it to the Early Planning page. Some discussion of it has already taken place in Slack.
    • Road map / timings
      • Steve: It would be good to have Phase 1 running in some form by the end of year holidays. That's only 4-6 weeks away. AMM will come very quickly in 2024. Need to keep tempo up.
      • Christian: What is in Phase 1?
      • Steve: Some discussion in previous calls and the minutes but detail is not recorded. Goal was to quickly hack an early PoC that allowed us to trial somethings and have code to work with. But let's create a summary now.
      • Summary scope added to Early Planning page. Attendees agreed scope.
    • MongoDB Realm
      • Some discussion of Docker support and connecting it to WAII.
      • Arnaldo informs that like SQLite its intended to be linked to an app, rather than provide a standalone service.
      • Some discussion will be needed how best to interface it. Could create a shim to allow WAII to read/write to a Realm DB.
      • Arnaldo will consider Realm aspects.
    • Proj Mgt
      • Discussion of Github Project limitation that seems to require people to be a member of the COVESA organisation to be able to assign them in Project tickets. Paul will add missing people.

1st November 2023

Minutes:

  • Central Data Service Playground
    • Holiday today in Germany
    • Project Management
      • Steve runs through what he has done for project setup. Github Project site and source rep created. Some tickets added. Links added to the project page.
      • People happy to try what has been created.
    • Source license
      • Steve: We will soon be creating code. Which license to use? There was some recent external queries about MPL-v2.
      • Paul: MPL-v2 remains the COVESA default.
      • No strong preferences expressed beyond something permissive.
      • Steve: Changing later can be a little painful so have a think and we can decide in a week or two. MPL-v2 is most likely candidate
    • DBs
      • No one present from MongoDB. DB discussed postponed. Steve will setup side meeting with Ulf and anyone interested in discuss WAII DB backend interface State Storage.
    • Related projects
      • WAII
        • Ulf: Peter Wenzell's work on updated Docker support and feeder for RemotiveLabs sim playback has been merged to Master.
    • Requests:
      • Please add any topic you think we should be investigating either to the Confluence Early Planning page or as a ticket to the Github Project.

25th October 2023

Agenda:

Minutes:

  • Christian input:
    • It would be good to define problems to be tackled down to guide project.
    • Similarly find use cases to illustrate/investigate problems
    • The group might maintain a set of use cases as a set of validation cases for the playground, e.g. made change but validation still passes.
    • Steve: Christian Muehlbauer please consider adding (better version of my poor notes) this to the project page as input
  • Ulf: VISS designed for wide range of use cases. This flexibility means that use cases may not be critical.
  • Ulf: Simulation only or deploy on h/w in a car?
    • Steve: personally I think both is possible depending on what is being investigated.
  • Humza: To what extent will the Playground contain application code to allow experimentation? Would there be controls demonstrating different setups for example.
    • This lead to discussion of resources vs goals.
    • Steve: we are resource constrained. Personally I would have the base code implementing the playground, e.g. VISS+store and then alongside have the PoCs etc that show it being exercised. Then you have a seperation of intent and you avoid problems of maintaining use case PoCs over time if that is not required.
      • Writes following tree to illustrate:
      • Playground functional base block: e.g. VISS + store
      • PoCs, e.g:
        • Large ECU sync PoC
          • Multi instance of the containers representing ECUs
          • With some marshal app code to exercise it
        • Internal trial PoC
          • Figure out the latency of cool new protocol
    • Christian draws good point to his earlier comment about validation cases. We might have some official 'exercise cases' that are maintained. Others agree based on discussion. The project/data-arch group may have some validation use cases that are maintained along with functional base block for validation and as they illustrate useful concept. Examples used for illustration in the discussion (not agreed list)
      • High frequency data feed
      • Medium frequency data feed
      • Hello World
    • Above discussions show that maintaining doc along side is important. Doc for use of functional base block, but also doc for the use cases. Supports understanding and adoption.
  • Project management / operations
    • PM task tool
      • Steve: what do we use?
      • Paul: suggest github. JIRA hard to discover and hidden away.
      • Richard: we intend to use github in AOSP project.
      • Ulf: github
      • Steve: I dislike that github kanban boards have poor support for comments and know JIRA well, but happy to go with majority.
      • Steve: how do rest feel?
      • BMW, MongoDB happy with github
      • Decision: Start with github kanban for project management
      • Action: Steve to create. Others to fill in their backlog ideas once announced.
    • Comms
      • Steve: what to use? We should try and move more of the day to day discussion online to support 24/7 and different time zones.
      • Decision: Covesa Community Slack. Create a new data-architecture channel.
      • Action: Steve to create new channel and announce it.
    • Phases
      • In workshop we talked about using incremental delivery to iterate the playground. What are the major early phases?
      • Discussion favours doing simple early PoC code to help decide on source and project organisation.
      • Decision: Needs refinement in the kanban board but first phase is 'create Playground PoC' along lines above.

18th October 2023

Agenda:

  • Meeting invite: Christian, Sri
  • AMM wash-up
    • Goal: what went well, could be better, sessions/input we should be aware of
    • General including input from related sessions, e.g. Ulf's southbound session
    • Data Architecture workshop
  • Central Data Service playground proposal
    • Goal: move towards project kick-off and work breakdown
    • Further input?
    • Agree next steps
      • Do we have general agreement/understanding on what we are doing regarding the service itself initially (the big picture What) and can move to getting the ball rolling on the details (e.g. checking docker status and choosing requirements of some use cases) of the how?
    • How to organise? e.g. Kanban, JIRA. Account for schedules and time zones by doing what we can online.
  • AoB
    • Adnan: serialisation
      • Looking at msg serialisation between vehicle and car. Requirement to keep flexibility in terms of what is sent.
      • BMW will have a researcher looking into this. Can something be done in open? Payload only.
      • Looking for input.

Minutes:

  • Serialisation
    • Adnan outlines (Adnan Bekan correct me if my summary is incorrect):
      • BMW will have a researcher looking into message serialisation between vehicle and car.
      • Scope is the payload only. Not the transport. However some flexibility in terms of what is sent in the payload is required.
      • Can something be done in the open in standardising this? Also looking for input on approaches.
      • Adnan notes the work done in the past during CVII Tech Stack days using AVRO with the esync alliance, but feels that is a heavyweight solution.
    • Various suggestions made about some possible approaches, such as encoding methods that take advantage of sparcity or lack of change.
    • Steve: the cloud connection has been cold for a while but only because its been waiting for someone to run with it. This should be of interest a wide group. I would recommend writing an outline or proposal of what problems you want to tackle down, along with some requirements. From that other inputs can be gathered along with people to work on it and a project formed. This should be of interest to the Commercial Vehicle group for example and their telematics requirements.
  • AMM wash-up
    • Christian: various gateway solutions appearing, e.g. PennyBecker, HIM, Vehicle API etc. Implementations at different levels. Would be good to understand what they look to achieve as some are not directly comparable.
    • Arnaldo: difficulty for newcomers to get started. Wiki can be overcomplex to understand.
      • Data Arch landing page needs cleanup / simplification.
    • Neil: Agree. Some attendees talked to showed interest, but not everyone understands.
    • General agreement for the need for more guiding documents like HowTos.
    • Steve: I intend to remake the Data Arch landing page as discussed before the AMM to make it easier for newcomers.
    • Other sessions - Ulf southbound architecture session
      • Steve: Peter Winzell said in the W3C slack that he was working on a southbound feeder to WAII connected to Redis. Is it related to your work.
      • Ulf: Peter is using the WAII feeder framework I described in my session. His feeder connects to the RemotiveLabs simulator. As part of his work he's also updated the WAII DockerFile to use the latest code.
  • Central Data Service playground proposal
    • Only 10 mins remained. Will be main topic next week.
    • Steve: Please consider what the near term next steps are, what use cases you want to explore and how we should organise the work
  • Meeting invite: Christian, Sri
  • AMM wash-up
    • Goal: what went well, could be better, sessions/input we should be aware of

12th October 2023 - AMM Data Architecture Workshop

  • (these are incomplete notes made after the event) 
  • Workshop delivered as planned, except for compression of timne time on doc proposal:
    • Mongo DB/BMW (9-9:45)
    • 10-10:15 break
    • Central Data Service Playground (10:15 on)
      • Part 1: Readout of the proposal
      • Part 2: Workshop the base components and the possibilities for 'spins' using it
        • As well as the names below Piotr Krawczyk Neil Puthuff and Halim Ragab actively engaged in the discussion, along with Arnaldo's colleagues. Apologies if I missed anyone from the list - let me know.
          • Piotr suggested MQTT as event queue (see whiteboard picture)
          • Halim was interested in the project but wanted to know the boundary performance (latency etc) of the Service to be able to understand how it would fit in the overall performance of an end to end touchpoint. He took an action to provide input on what GM requires.
        • Outcome: Ford (Ulf Bjorkengren), BMW (Christian Muehlbauer), MongoDB (Arnaldo Vera Humza Akhtar) and Renesas (Stephen Lawrence ) all expressed interest in actively contributing. Enough interest to begin the project.
        • Whiteboard Images:
        • Group shot after the end of the session:
    • Documentation proposal discussion: 30 mins to be fitted in
      • As the Playground workshop was going well this was condensed with Steve simply showing some slides on the wider eco-system need for documentation on HowTo's etc.
