17th July 2024

Agenda:

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

Minutes:

• Playground Kanban "stand-up meeting": In-progress task status, major new items
• Fall  AMM: https://wiki.covesa.global/x/WgBSBg. We need to firm up plans as the end of month is approaching. This is in part also a discussion of the group roadmap towards the AMM.
• AoB
  • Christian: Simulators

Minutes:

• Playground Kanban 
  • Christian expects to make greater progress on Knowledge connector next week
  • Steve is working on an example for the IoTDB data processing PR. He's got ok from RemotiveLabs to use some of their data.
  • Steve has been contacted by Halim from GM. He is checking the uProtocol Simulator status
  • Knowledge Layer Connector
    • Christian asks about connecting to IoTDB in the Playground
      • During development phase can simply connect to the iotdb-service container running the IoTDB server either from host or another containers as you wish.
      • For deployment we will need to discuss how to integrate the connector, but for example it could be a knowledge-layer image that becomes a service in the playground compose.
• Fall AMM
  • BMW internal meeting was pushed back. Christian should have news next week.
  • Steve: Chicken and egg on workshops. Holding workshop on playground internals will depend on participation else it might make more sense to join the verticals (commerical, safety, insurance) and discuss use-cases and playground use.
• Simulator
  • Christian: we have been thinking internally about connecting simulators to the Playground, including the information layer and I wanted to discuss this publically.
  • Discussion:
    • Various simulators will be needed.
    • It's agreed its helpful if only minor glue code is needed to make connections. For that to be possible appropriate documentation is needed for interface integration.
    • Some 'playback' will be as simple as ETL style operations of loading data sets into the DB
    • Standalone collection of data sets reusable across examples is a need.

10th July 2024

Agenda:

• Playground Kanban "stand-up meeting": In-progress task status, major new items
• Knowledge Connector
• DB Schema generation: I will like to briefly present the generator diagram from slack to both get early feedback and to progress the discussion
  • https://drive.google.com/file/d/14cxCzfcIVgJA3yyStnjcu1D4PxQFE3M9/view?usp=drive_link
• Fall  AMM: https://wiki.covesa.global/x/WgBSBg
• AoB

Minutes:

• Kanban meeting:
  • Waiting on GM to return from break for uProtocol simulator update
  • IoTDB Data Processing functions: Steve has updated the PR to add online documentation for the changes.
    • Next is Grafana, plus an example
  • Knowledge Connector: Christian explained updates to the PR, e.g. DB router changes.
    • Discussion in the DB Schema section about challenges of maintaining a single source of truth when relating data models as is typically needed with knowledge layer.
    • For the connector itself it seems ok if it uses a particular approach to communicate the wider idea of using Rules based reasoning. That is internal to the blackbox and other approaches could be used in implementation.
• DB Schema:
  • Continued last weeks discussion.
  • Steve explained a diagram that communicates the thoughts he had last week. Diagram here: https://drive.google.com/file/d/14cxCzfcIVgJA3yyStnjcu1D4PxQFE3M9/view?usp=drive_link
  • Discussion of some ideas there and the challenges when representing relationships between models as needed in knowledge layer.
• Fall AMM
  • Steve has created a brain storming page https://wiki.covesa.global/x/WgBSBg
  • Christian will check internally what BMW want to do and who will attend.
• Summer holidays:
  • Ulf: off next week and 1 after. Probably some further break later in summer.
  • Sven: 3 week break coming up.
  • Christian: Long break from 8th Aug.
  • Steve: will take 1-2 week break, probably in Aug, to match when others are off.

3rd July 2024

Agenda:

• Playground Kanban "stand-up meeting": In-progress task status, major new items
• Docker: Brief summary of my PR above.
• DB Schema generation: I had some discussion with Gunnar in CVI about this. Basically keeping the meta-data for it with VSS as a layer, rather than dislocated in for example a template language config file. I think ultimately I need to write a fuller proposal that can be discussed, but it perhaps warrants a short discussion if people have input to help form the ideas.
• Fall AMM: deadline for talks is end of the month. We need to discuss what we want to do, including the possible extra technical day.
• AoB

Minutes:

• Kanban stand-up meeting:
  • Knowledge Layer Connector, Christian: Started on skeleten PoC DB router in information layer
  • IoTDB Data Processing, Steve: A WIP PR has been added https://github.com/COVESA/cdsp/pull/52 which adds the optional IoTDB Data Quality Library to the Playground IoTDB docker image and configures IoTDB for access from Grafana.
  • uProtocol Simulator: waiting for update from GM
• DB Schema Generation:
  • Discussion of providing a mechanism for DB Schema generation for VSS nodes. This would accelerate users ability to more quickly get started with the Playground as it could automate the generation of all nodes.
  • Steve and Christian think this could be useful. Christian in addition raises a similar use-case for the knowledge layer, e.g. SHACL generation. There was some conversion to SHACL in the past.
  • Idea brainstorming:
    • Rough requirements:
      • Input: VSS vspec (a reduced vspec could be input if only a few nodes are required)
      • Generation:
        • Template language + config (config is the description needed to match VSS to the DB)
      • Output: schema for DB X
        • Example: Series of lines to create schema for each VSS node e.g CREATE timeseries.Vehicle.Speed (datatype=INT, compression=X, encoding=Y, meta-data=Z)
    • Steve: In discussion with Gunnar in CVI it was considered that this mapping meta-data could be held in a VSS layer/overlay (closed to the source) rather than in an isolated stand-along config file. If the existing VSS overlay mechanism did not support it, then evolving VSS overlays to be something closer to IFEX layer mechanism could.
  • VSS layer:
    • vehicle.speed DB meta-data=> data-type=INT, compression=squashy, encoding=super-encoding, meta-data="some attribute"
  • Generation / vss-tools:
    • Christian asks about doing this in vss-tools.
    • vss-tools has good set of meta-model functions now, which means generator largely just needs to contemplate output side so could have:
      • vspec2iotdb
      • vspec2realm
      • vspec2shaql
• Fall AMM
  • COVESA wants technical session proposals by end of the Month.
  • So we need to contemplate:
    • Weds/Thurs Main Conf: Technical Sessions
      • e.g. Outreach etc.
    • Tues Smaller Conf: Workshops
      • e.g. Playground internals
  • Steve will put up the usual page for ideas
  • Paul: COVESA page here All Member Meeting Planning

26th June 2024

Agenda:

• Playground Kanban "stand-up meeting": In-progress task status, major new items
• Docker: I have been working on integrating the IoTDB Data Quality library and Grafana. That raises some questions about configuration of Docker containers and the source for the parts we integrate. That may be worth a discussion to get some feedback. Particularly from the BMW team who may be doing similar work at the moment.
• @Swen Schisler (Endava) mentioned last week wanting to discuss some of his proposal to the CVI group
• AoB

  • Proposal for integration of VISS into the Knowledge Layer connector
• AoB

Minutes:

• Playground Kanban stand-up

• GM were scheduled to update us on the uProtocol Simulator but no GM representatives attended.
• Continuation of the two topics @Ulf proposed last time and briefly introduced
  • Playground documentation structure
    • Ulf described his proposed updates to layout of the landing page and organising the examples.
    • Screenshot: Ulf-CDSP-doc-layout.png
    • Steve described original was modelled after the Docker landing page which does a nice job of enabling both newcomers and experts: https://docs.docker.com/
    • Ulf's point about seperating the user/ref manuals of the core components would be useful
  • Proposal for integration of VISS into the Knowledge Layer connector
    • Agreement that the pluggable architecture in the WS component for DBs would allow Ulf to attach some of his idea, e.g. he feels he could use OVDS to attach VISS in the cloud.
    • Discussion of other aspects
• AoB
  • Swen mentioned he could discuss some of his ideas for his project next week

12th June 2024

Agenda:

5th June 2024

Agenda:

• Playground Kanban "stand-up meeting": In-progress task status, major new items
• uServices mocker integration discussion with GM team
• Time permitting or uServices discussion does not proceed: Knowledge Layer connector example
• AoB

Minutes:

• Playground Kanban stand-up
  • Steve has made the 0.1.0 release. Currently working with COVESA marketing to publicise
• uServices Mocker discussion
  • Halim set the big picture. Mocker in question is the Eclipse uProtocol Simulator. Mocker seems a good fit for the concept of the Playground.
    
    • From project README.md: The up-simulator is a user-friendly web tool designed to make developing uProtocol services and Apps on PCs easy. Its intuitive interface empowers users with features such as Publish-Subscribe, RPC invocation, and the simulation of COVESA Vehicle Services. With a focus on a user-friendly graphical interface (GUI), users can easily navigate through the development and testing phases of uProtocol Apps, ensuring a smooth experience from start to finish.
      
  • GM engineers demonstrated the simulator for uProtocol and vsomeip traffic.
  • Halim: whilst the simulator supports uProtocol and uServices it can be used to simulate pure SOME/IP traffic.
  • Steve: as the simulator already exists it seems to be a question of how the 'tool' would be integrated and connected to other components to add value. Is it containerised?
  • Simulator is implemented in Python, but not yet containerised.
  • Halim suggests that GM containerises the simulator and that is then used to guage wider interest. This seems like a sensible way forward.
  • Halim: there will be a company stop in around a month for a summer break, so I would like to push the GM team to make some progress in the next two weeks. Let's plan for a progress update from the GM team in the Data Arch call for 19th June.
• Knowledge Layer Connector example
  • Ran out of time. Pushed back to next week.

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.

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.

   6. Feeders incl WAII, Volvo/Remotive
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.

    • Apache IoTDB: Steve has implemented 'set' connector for WAII locally. Code is available in his github fork. Preparing PR to both Playground and WAII.
    • Realm:
      • Steve met with Humza/Arnaldo last Friday to show his integration into WAII
      • Currently Arnaldo considering how best to do the integration. Options include adding Realm as a State Storage backend for all data, e.g. like Redis and IoTDB, or using it in a supporting role where it makes sense, e.g. sync or in Example.
  • Ulf announced he is adding https://memcached.org/ (fast simple key/value pair in-mem store) as an additional State Storage backend to the WAII VISS Data Server.
  • Knowledge layer connector
    • Haonan has posted first draft of problem outline for the connector to slack in document form whilst she sort out Confluence access:
      Covesa Playground Piece_ Data Converter between DM and Reasoner-v21-20240214_101149.docx
    • Group needs to do background reading to come up to speed on the topic.

7th February 2024

Agenda:

1. Spring AMM sessions
2. Central Data Service Playground
   1. Based on discussion with Christian Muehlbauer kick off discussion of Connector in the Playground between the data and knowledge layers
   2. Ulf has sent a PR to add the Hugo online doc: Any discussion needed related to that, e.g. workflow, review
   3. Database connectors: status, handling WAII changes
   4. Feeders (time allowing)
3. AoB

Minutes:

• Spring AMM sessions: nothing to discuss this time
• Central Data Service Playground
  • New feature idea: Connector between the data and knowledge layers in the DIKW pyramid
    • Kick off of discussion first discussed in previous weeks.
    • Possibility to use BMW Research WS to RDF Converter (see Christian presentation below). Christian has some personal leave in coming weeks. Haonan will step in.
    • Haonan offers to do technical overview presentation of converter.
    • Steve suggests using the proposed Artifact design methodology (simplified) as a means to working through what such a Connector should achieve for the Playground. No dissentors. Haonan agrees.
    • Way forward:
      • Haonan will do a technical overview presentation in a future meeting. Goal: group better understands the converter. Date TBD once she is ready.
      • Haonan kindly agreed to do a first draft using the design methodology to define what a Playground Connector should be from her perspective (domain expertise). This can then be used as a basis for wider discussion in the group.
      • AI: Track in meetings.
  • Online documentation
    • Ulf has posted PR to add Hugo static website generator. He needs support to add github workflow to automatically build the doc and publish. AI: Steve to work with Ulf on that.
    • Requst to review PR. Will look to merge in next week.
  • Database Connectors
    • Steve has the 'get' connection between WAII and Apache IoTDB done. Preparing to make code public. He expects 'set' to be added this week.
    • Humza reports that the Realm DB C++ process is done. Just need to integrate into WAII. After discussion Steve will meet with Humza/Arnaldo to do a quick return of experience with his integration to accelerate adding Realm.
    • Answer to question of how to manage WAII changes before they are upstreamed becoming more urgent. Steve will likely create WAII fork so they can be managed in the submodule to keep us moving.
  • Feeders
    • Short discussion of feeders

31st January 2024

Agenda:

1. WAII update
2. Spring AMM sessions

    • What are the big picture things in the backlog?
      
      • Source license
      • On-line (Hugo) doc PoC
        • Christian: It would be useful to paint the big picture of relationship to other projects. I can perhaps contribute something in that regard
    • Contributor outline
    • Source documenation

24th January 2024

Agenda:

1. Spring AMM sessions
2. Central Data Service Playground
3. AoB
   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.
    • Discussion on what components might be open sourced and could be integrated. RDF converter would be a good candidate to examine for providing a connector between data and knowledge layers.
    • 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

Minutes:

• Discussion of Spring AMM sessions.
  • AMM Commitee wants to make schedule public end of Jan
  • Data Arch planning page here 2024 Spring AMM Planning (Data Architecture and Infrastructure). Feel free to add your ideas there.
  • Steve proposes three linked themes for sessions on the Playground
    • High level intro (why, what)
    • Technical overview (more detailed on how and the code)
    • Focus on using the playground through examples. Akin to the BMW presentations in prior AMMs.
  • General agreement that would be good approach.
• Central Data Service Playground
  • Steve summarises Friday meeting with Arnaldo and Christian/Haonan. Succesfully worked through Arnaldo's issues with WAII Docker bring up.
  • Arnaldo documented list of gaps in instructions for a clean build.
  • Steve used this to raise additional issues in WAII github with doc or code gaps.

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.
  Apologies: Ulf, possibly Christian
