The W3C Vehicle Signal Server Specification defines a WebSocket based API that enables client applications running on the In-Vehicle-Infotainment system and on the local vehicle network to access vehicle signals and data attributes. The purpose of the specification is to promote a Server API that enables application development in a consistent manner across participating automotive manufacturers.
There are two parts to this specification, Core and Transport. This document, the VISS version 2 CORE specification, describes the VISSv2 messaging layer. The companion specifications for the VISSv2 transport protocols detail the mapping of the messaging layer to selected transports. The ontologies based on the VISSv2 core specification are defined in documents for each specific domain (e.g. navigation, media, vehicle data).
