Submission request to W3C

Submitted Materials

We,

Mark Beckmann
Dr. Patrick Bartsch
Patrick Luennemann

, hereby submit to the Consortium the following specification, comprising the following document(s) attached hereto:

which collectively are referred to as "the Submission". We request the Submission be known as the Volkswagen Infotainment Web Interface (viwi) Submission.

Abstract

With the Volkswagen Infotainment Web Interface (viwi), applications running on an in-vehicle infotainment (IVI) system or any device connected via TCP/IP get access to the systems resources and functionality. The interface is based on web technologies. The goal using web technologies (HTTP, WebSockets) is to create a convienient API for developers on both ends, the system and the application(s). Viwi is a restful service interface, which promotes (micro) service system design patterns. At the same time, viwi utilizes standardized web security mechanisms like TLS encryption, OAuth or JWT tokens. The API is designed in a graph-like fashion to allow interconnection between services. Viwi is treating the car like a web service from an API perspective - REST extended by publish/subscribe for high frequency changes.
