Agenda:

Minutes:

  • No meeting. Only Steve and Iyaz joined.

4th December 2024

Agenda:

  • Status sharing including Playground Kanban
  • Christian has an updated Knowledge Layer C4 Model to share
  • Any input on VSS Database schema generator proposal
  • Data Architecture Team confluence page updates
  • Need to start considering Xmas breaks

Minutes:

  • Xmas breaks
    • Steve last day is Friday 13th.
    • Decisions: Next weeks call 11th Dec is last of the year. First meeting of 2025 is 8th Jan.
  • Playground
    • Kanban:
      • Steve went through his changes:
        • Add initial C4 Model diagrams to Github. See \diagrams\*.drawio.svg. The google drive file with multiple tabs is now a working copy for the newer diagrams.
        • Document Playground online documentation site. See \doc\readme.md
        • Redid the Data Architecture team confluence landing page. Further future improvements possible. Christian likes that it summarises the focus on data-centric arch and the info layers.
        • Following the topic coming up again last week drafted a proposal for DB Schema generation for VSS based on the existing diagram. Proposal can be found in the Data Arch confluence wiki VSS Database Schema Generator. Asked for feedback on slack. Daniel Alvarez provided some input on VSS channel regarding handling of VSS instances and whether working from an API spec would help.
      • Christian summarised BMW team changes:
        • Some updates to the RemotiveLab feeder to limit the inputs. Made for the current code base and use-case. Expect to improve this in the future.
        • He has updated C4 Models for the KL and IL changes.
          • Extended CDSP Container diagram. Added L3 for IL and KL.
          • He will ask Haonan to fill out KL container components.
          • Steve will add the diagrams to the google drive file.
  • NoSQL Document DBs
    • Rami Pinto explained that MongoDB have a draft proposal for the work he mentioned last week to describe best practices for integrating VSS data into a NoSQL DB.
    • They will present this in an upcoming meeting. He's away next week. May wait till next year.


27th November 2024

Agenda:

  • Status sharing including Playground Kanban
    • C4 Model pull request is ready for review
  • We can continue Knowledge Layer discussions from last week
  • Rami from MongoDB wanted to discuss DB enablement, automation and best practices

Minutes:

  • Playground
    • Status
      • Christian is absent from the meeting (travelling)
      • Haonan is back from vacation and summarises her recent work on the knowledge layer.
      • Steve summarises the short term backlog for Haonan.
    • DB enablement, automation and best practices
      • Rami explains how MongoDB is looking to become more involved again. How does Atlas fit in?
      • In terms of the Knowledge Layer work the proposed sync meeting with Christian is needed.
      • Some additional possibilities are discussed:
        • Rami suggests best practices for Document databases. They had a customer conversation recently where they asked about how best to integrate VSS
        • Example showing how to integrate with Atlas
        • Steve outlined the previous discussions about a DB DDL schema generator for VSS.
        • Rami is encouraged to bring proposals.

20th November 2024

Agenda:

  • Playground
    • C4 Models
      • PR for Github - readme, location, discoverability
      • Christian Container model extension
      • Deployment diagram - dev vs live
    • IoTDB version update
    • VISSR version update
    • Christian:
      • Discussion RealmOS instead of RealmSDK within Information Layer
      • MongoDB Atlas as additional backend?


Minutes:

  • Playground
    • Answering questions from newcomes from Cobrasphere and MongoDB
    • C4 Models
      • Christian introduces his draft extension of the CDSP Container diagram to include the Knowledge Layer components
        • Steve: great to see this. Very helpful for discussion. We might remove the Fleet and Insurance example boxes to simplify. Also some minor points about connectors.
      • Steve has a WIP PR to add the L1 Context Diagram and L2 Container Diagram to the source
      • Steve shows some hacking he did for a Deployment diagram for the CDSP core in a development environment.
    • IoTDB version update
      • Steve was targetting v1.3.2, but v1.3.3 dropped a couple of hours ago which adds AINode (LLMs in SQL) and improvements in sync and subscriptions. So will likely refocus on that.
      • Also need to schedule the sync discussion with their community.
    • Knowledge Layer
      • Christian suggests that with deprecation of RealmSDK that KL will move to adopt Realm OSS community edition instead. This will leave a unfufilled requirement for DB sync.
      • MongoDB interested in how Atlas can be utilised in cloud side implementation. Christian wonders if it should be an additional backend to the DB abstraction (Information Layer)?
        • Conclusion: Further discussion needed.

13th November 2024

Agenda:

  • Playground kanban and status exchange
  • Data-arch discussion in Monday's AOSP call
  • Capabilities API

Minutes:

  • Steve summarised data-arch discussion in Monday's AOSP call that Richard gave us the heads-up about.
    • Steve mentioned to them work elsewhere in COVESA they could leverage, e.g. Capabilities API Seat as a source.
    • Conclusion: They are very early in their discussions. Should monitor and input where possible.
  • Steve summarised status of Capabilities API work

6th November 2024

Minutes:

  • Playground
    • Knowledge Layer
      • Input from Christian before meeting:
        • Knowledge Layer Connector is now largely finished. Now they are testing triple formatting and writing rules.
        • They are also starting to connect the RemotiveLabs feeder to the Information Layer Connector.
      • Steve has started to look again at the code as preparing for review. He sees some topics in the IoTDB integration that need aligning with what already exists, e.g. database paths and handling of VSS path naming.
    • Steve has started to look at the VISSR and IoTDB version upgrades.
  • AOSP
    • Richard summarises the result of the AOSP group survey about what should be next. One of the findings relates to southbound data transformation. What that may mean in terms of work streams will be discussed in the AOSP call this Monday.
  • Ulf reported that the CVIS work for Commercial vehicles has restarted in recent weeks.

30th October 2024

Agenda:

  • Catch-up after two week hiatus
  • KL updates from Christian
  • Data sets
  • OEM news

Minutes:

  • Playground
    • Knowledge Layer
      • Christian gave a summary of updates to the Knowledge Layer pull request over the two week hiatus, including a walk through of the document for the hello world example
      • The example requires one additional data key that is not in VSS. Ulf mentions work on HIM merged in current VISSR that could be used to model the two data models (VSS and personal data)
      • Christian: Has RDFox been in contact about licensing?
      • Steve: not seen it yet, but not completely through my email backlog.
      • Christian will ask.
    • Data sets
      • Whilst in Japan Steve recorded some travel data (speed, location and elevation) on the bullet train with an eye on transforming them into VSS for use as an open data set.
    • OEMs
      • Steve mentions that during a Honda keynote at the recent Open Source Summit in Japan by Tsubouchi-san there was mention of an in-vehicle data lake that appears to support the approach of the Playground for hybrid in-vehicle and off-board data processing.
