COVESA VSS Wiki

The VSS page on this wiki is a good starting point that leads/points to all of the other locations.   

• VSS One-PagerOverview - High level overview of VSS
• Introduction to VSS Sessions - Every Quarter, starting Q1 2023, there is an Intro to VSS.  Presentation and recording of the session are available.
• Understanding VSS - Presentations and decks starting with an introduction to those unfamiliar with VSS followed by some deeper dives into VSS and related VSS Ontology
• Vehicle Data Models - Overview and Gap Analysis - Survey of vehicle data models
• Weekly MeetingMeetings - See the Community Calendar
• Weekly meeting time : Agenda and linkNotes

GitHub

GitHub is where almost all of the VSS project work is maintained.  TheThe main page contains links to   

• Documentation

• A straight forward set of topics that give a good overview of VSS

• Releases

• Release links with lists of what has changed

• Specification/Catalog

• VSS specification refers to the standard catalog. It is maintained in yamlYAML.  It is fully expected that not everyone will implement all data elements/signals and they will likely implement some number of proprietary elements/signals.  VSS is still a useful methodology/rule set for defining interoperable models.

• Tools

• Tools are maintained in a separate repository

• GitHub Project wikiWiki

• VSS project team uses the VSS wikWiki for documenting a variety of things including releases.

• Pull Requests 

• All edits and updates are presented to the team through Pull Requests and are discussed in weekly meetings.

• Issues

• All issues are tracked through GitHub issues

...

There are various implementations where VSS is used as data model for vehicle data.  Beside several closed-source implementations, here are the ones that are shared publicly:

• playground.digital.auto - playground for ideation and collaboration  between digital.auto participants using VSS and python. 
• Aos Edge - A software first approach to the connected vehicle.
  • Provides a protected VSS data server that uses the VISS protocol, VISS client library and a 'getting started' example using VSS as the data model.
  • Source repositories
• Eclipse Kuksa - Building blocks for the Software Defined Vehicle
  • Repositories and other Resources
• AWS IoT Fleetwise - Fleet Management software
  • Repositories
• W3C Vehicle Information Service Specification - data service for serving VSS data on multiple topologies

...

OEM and Supplier Adoption

• BMW
  • Mapped proprietary descriptions of vehicle data to VSS, for millions of cars.
    
  • Employing GraphQL to create a backend single access layer for querying data coming from various storage and streaming systems. Demonstrated backend application based on this solution. While for data streaming use cases, other technologies that are supporting VSS might be in place.
• Volvo
  • VISS implementation, exposing VSS within the vehicle
  • Ideas for Vehicle Signal Set Matching
  • Dynamic weight generation for vehicle signal set matching.pdf
• Ford 
  • EV Charging Event Data Aggregation project led by Ford is actively updating the VSS model for EV Charging 
  • Internally working with VSS as a starting point for a variety of data related and development projects
• Mercedes 
  • Internally working with VSS as a starting point for a variety of data related and development projects
• BlackBerry
  • Used for signal normalization in the BlackBerry IVY product.

Spotlight Series

...

COVESA Spotlight is a series where member organizations from the COVESA Community present their use/implementation of COVESA's Vehicle Signal Specification answering the following questions:

• Why VSS was used? / The value of using VSS?
• How VSS was used?
• What could be improved in VSS?

You can find the past presentations from the series here.  If you are interested in presenting your VSS implementation, please contact the Community Director.

Joint Projects with W3C 

Covesa has joint projects to develop and standardize certain technology through the W3C process.
