Kuksa.VAL	Sebastian (Bosch)	--
VISS server implementation in Go	Ulf	--
VSS & Tools	Daniel Wilms (BMW) Gunnar (Sebastian as backup)
VSSo	Daniel W Ted	Formal publication plans continue. Transition to W3C working group. VSSo → DTDL translation (still) exists.
VSC & Tools	Gunnar
W3C VISS specification	Ted Ulf	Access control PRs moving forward, and some specification text changes. (more details see last week's minutes on COVESA Wiki)
CCS-components	Ulf	Updated picture (PR sent)
AOS	Artem	Publishing started. Hopefully links to source within a week.

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.)

From now on, refer to COVESA Wiki

Project	Person reporting	Updates
ioTEA/Vehicle Edge	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.
Kuksa.VAL	Sebastian (Bosch)
VISS server implementation in Go	Ulf	Access control and curve logging planned demo for AMM so those features have been tested and some fixes recently.
VSS & Tools	Daniel Wilms (BMW) Gunnar (Sebastian as backup)	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
VSSo	Daniel W Ted	(Preparing presentation for AMM)
VSC & Tools	Gunnar	Parser/generator working with updated service-description file (which includes some changes to the IDL language).
W3C VISS specification	Ted Ulf	Discussion/finalizing updates on access control: - bandwidth savings and server-caching of tokens - alternative (simplified) access-control model proposal
CCS-client repository	Ulf
AOS	Artem

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.
