This is the landing page for the Architecture and Infrastructure pillar of the Data Expert Group.

Introduction

The scope of the group is any technologies (software) involved in the transfer and use of the Covesa standard data and services description models with the goal of making their adoption quicker and easier. That can be achieved through collaboration on specifications, design patterns, non-differentiating technology and PoCs to prove they work.

Building on earlier work

The Genivi Cloud & Connected Services (CCS) project investigated the requirements of open data capture in-vehicle and its connection to back-end systems in the cloud. One of the deliverables was this well known reference architecture diagram:

CCS was followed by the Common Vehicle Interface Initiative (CVII) Tech Stack project which investigated the software required to transfer and process the standard VSS data model. For that a mutual understanding of terms and common components were required. The latter resulted in this in-vehicle architecture diagram:

Communication

Currently the group meets weekly on Wednesday afternoons at 5pm CET. See the Data Expert Group main page for details of the community calendar and communication channels.
