DAPR - evaluation, discussion, plans for VSS integration
Initial code drops from BMW. Full signal-source (SOME/IP) to GraphQL data server, serving VSS data.
Note: All parts of the end-to-end are not here yet, but these initial 3:VSS serialization reusable C++ library? (not discussed today in particular - but note that serialization/messaging format remains a need for connecting to the frameworks such as DAPR and other transparent "transports" that do not define a format yet.)

No regular meeting due to ongoing AMM
Wednesday 2021-09-29
Project | Person reporting | Updates |
|---|---|---|
| Mike Haller (Bosch) Thomas Spreckley | Automated package/docker container image deployment. Gunnar prefers to delay upgrade of account types (GitHub, Docker Hub etc) until after next week. |
| Sebastian (Bosch) |
|
| Ulf | Access control and curve logging planned demo for AMM so those features have been tested and some fixes recently. |
Daniel Wilms (BMW) | Implementation proposal for unit file. Close to ready but some details (e.g. where to store config) are pending. VSS-Layer discussion planned 2 weeks from now | |
| Daniel W | (Preparing presentation for AMM) |
| Gunnar | Parser/generator working with updated service-description file (which includes some changes to the IDL language). |
| Ted Ulf | Discussion/finalizing updates on access control: - bandwidth savings and server-caching of tokens |

Minutes
AASIG code gen, some progress. Working on adding type-conversion into generated code. Code still in Manu's fork. PR not sent yet.
Stephen: Started looking into time-series databases. Plan to connect VSS data server (using Go-implementation VISS?) to the database APIs. InfluxDB, IoTDB, ...
Wednesday 2021-09-22
Project | Person reporting | Updates |
|---|---|---|
| Mike Haller (Bosch) Thomas Spreckley | CI/CD integration mostly finished. Extended reports (JUnit) Unit testing working. SDK bug fix, was not reading config files. Vehicle Edge - phase 2, seat-adjuster demo. (Discussions on VSC started, driven from this). |
| Sebastian (Bosch) | Pending PR allowing Kuksa.VAL to load several VSS files at start up (supporting layer idea) |
| Ulf | Minor bug fixes |
Daniel Wilms (BMW) | Accessory setting for ignition switch was missing, proposed to be added in a PR
| |
| Daniel W |
|
| Gunnar | No VSC meeting this week (biweekly) |
| Ted Ulf | Major discussion on caching of access-tokens, mandatory or optional, behavior of server and client if token is used but not found in cache, etc. |
| Ulf | Minor fixes. |
| Artem | Discussions about how to design edge-computing, with one Tier1 and one IAS provider, with relationship to CVII topics. |
Apologies

Minutes
VSS-tools, A bit of additional progress in Android Automotive Vehicle Properties (VHAL code-generation) (Follow along in code_generation branch in vss-tools (and Manu's fork))
Discuss possible automatic unit/scaling
Time-series database implementation, see CVII Tech Stack
Discussion with Stephen/Renesas about this point.
Stephen: There is a dataset that exists from previous demos. (Values and timestamps) that could be used as data (after aligning it to VSS standards)
Stephen (sharing screen): Many values look like Snapshots ( according to this definition), i.e. several signals measured the same time.
Gunnar: Yeah, the snapshot format suggests to only store the timestamp once, if it is measured at the same time.
Gunnar; Note "same time"/simultaneous might include a short time interval since the meaning of simultaneous is a bit sketchy in a discrete system.
Tom: You can also reduce size of time stamps by transferring a delta-time compared to some reference.
Gunnar: Good point, worthy of adding a note to Data serialization / value formats page.
Reminder: Register for AMM if you haven't.

Daniel Wilms (BMW) | First presentation of a set of new VSS signals proposed by ExcelFore and eSync Alliance in the areas of SOTA-metrics, Battery Mgmt, ... vspec2yaml finally merged.

Minutes
Discussion about how to integrated (tagged) version of VSS into IOTea out of the box. Generated files are automatically inserted into Hugo documentation and can be downloaded from there, but otherwise using the git tag.
(Bosch) Idea brewing: Educational (University) involvement - build curriculum / community of students?
Android Automotive Vehicle Properties (VHAL code-generation) is now making progress (Follow along in code_generation branch in vss-tools (and Manu's fork))
Wednesday 2021-09-08
Wiki was down so these minutes were taken offline, and later added:
1. Standard project updates
Kuksa
Unit tests for gRPC code
Investigating switching from Jenkins to GitHub actions
ioT-event-analytics / vehicle-edge
Working on npm packaging (npmjs organization account now exists)
Quality checks/
Suitcase demonstrator including hardware, includes gRPC to communicate with Vehicle
API. RPi ARM 64 bit.
VSSo
Refine first version
A bit more structure to the process
Discussions continued with Microsoft, conversion to DTDL
VSS
Continued discussions on units and datatypes
AOS
Additional discussions with various stakeholders in industry. Want to get the code and
the container (definition) specification into the open. Registration framework.
Some inputs drive toward constrained environments. Small efficient implementations
required for data-servers The full Go-lang VISS server might not fit, k3s and others
might also not "fit".
Higher modularity is preferred
VSC
PR + examples added to master branch in the VSC repository.
vss-tools (Android)
A document provided to outline plan, and basic file structure
Looking for strengthening the implementation team
VISS
Improvements being done from feedback (pull requests) based on the first public
working draft
2. Other minutes
Mike Haller (Bosch) introduces himself. New product owner for IoTEA.
Artem EPAM might have developers free in 2-3 weeks
AMM update, reminder to register
