The author (Stephen Lawrence) intends for this proposal to facilitate the Data Architecture team in particular and the wider Data Expert Group to find a shared view on documenting Data Patterns and Data Architecture. Contribution is therefore encouraged by commenting inline, contacting the author or in the Data Architecture calls. |
This page describes a proposal to move towards joint work on documenting Data Patterns and Architecture after the Spring 2023 AMM.
Following a summary of where we stand, a proposal is made for a possible way forward. The author does not intend the proposal to be a fully formed work plan, but a skeleton roadmap on which the Data Architecture group and the Data Expert Group can iterate on to form one. An important principal is open discussion on what issues need to be tackled down, what is needed to form common understanding and sense of purpose.

Covesa has a range of source material from which to use.
This includes historical work from projects such as Genivi Cloud & Connected Services (CCS) project which investigated the requirements of open data capture in-vehicle and its connection to back-end systems in the cloud and resulted in a high level architecture concept.
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:
This evolved into contemporary work in the Covesa Data Expert Group including the Data Architecture pillar of the Group. For example the results from the first workshop included a high level scope to focus on zonal ECUs and above for the functional integration and data architecture. In addition high level deployment scenarios were sketched for in focus uses cases including IVI, Smart device, Car2Cloud and Cloud2Cloud.
There are also various presentations from meetings and the All Member Meeting (AMM) conferences. For example this input on Data Centric Architectures.
Finally there is individual work intended as contribution to the group work such as the authors work in his vss-otaku project, which includes discussion of combining VSS data stores and data servers.
As the number of adopters of Covesa technology, including VSS, has risen greatly we have seen increasing demand for descriptions of what it is intended for and how to use it.
