Team Comment on the "Volkswagen Infotainment Web Interface protocol specification (VIWI protocol) (version 1.9.0-w3c)" Submission

W3C is pleased to receive an updated submission from Volkswagen AG on the ViWi protocol.


The Volkswagen Infotainment Web Interface protocol defines a framework for exposing HTTP-based protocol and APIs for being able to access within a protected Local Area Network (LAN) various services provided by a vehicle. The service definitions that were part of their previous submission cover vehicle signals (telematics data, eg speed, engine temperature, door state etc) [1][2], media services, media libraries and other stored content. In addition to HTTP requests, data can be available continuously as updates are available through a WebSocket.

Related Work

The W3C Automotive Working Group (WG) was rechartered to continue work on its Vehicle Information Server Specification which is a WebSocket service for accessing vehicle signals data based on the data model in Genivi's Vehicle Signal Specification (VSS) and an as yet unpublished successor drawing influences of the initial approach and ViWi in a RESTful Service Interface.

Future Work

The Chairs of both the Automotive WG and the Automotive WebPlatform Business Group (BG), Team Contacts and group participants will review the updated viwi materials and draw from VW's experiences in deploying this technology, especially the rationale leading to this updated Submission.

Continuing discussion of this topic is welcome via the Automotive Working Group's public email list public-automotive@w3.org [archive].
