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

Introduction

The COVESA Logical Architecture shows the Data Expert Group scope as being the large ECUs and above.

Within this the Architecture and Infrastructure pillar is currently concentrating on data-centric architectures.

From the perspective of a DIKW Pyramid there is an emphasis on the needs of the Information and Knowledge layers in-vehicle, mobile devices and the cloud.

This means 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.

Projects

Information on the current projects, such as the Central Data Service Playground, can be found in the project list.

Related earlier work (Cloud and Connected Services, CVII Tech Stack)

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 cloud reference architecture diagram:

Source: CCS Reference Architecture - Work Breakdown Structure

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, which is intended to show the likely in-vehicle components and how they interact, rather than specify a specific monolithic architecture:

These two diagrams, the CCS Cloud reference architecture and the CVII Tech Stack in-vehicle architecture will be foundational building blocks for discussion of evolved versions in the Data Architecture and Infrastructure team.
