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.  

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.
