Why Central Data Service?

• A repeating pattern of discussion in the Data Architecture pillar is the combination of VSS Data Server and VSS Data Store and their connection southbound to feeders/native data and northbound to clients and off-board. Hence Data Service.
• VSS is a mechanism of abstraction. The logical architecture for the Data Expert Group and VSS places operation in the zonal ECUs and above. Discussion of next-gen and data-centric architectures suggests investigation into data services in zone, domain and HPC controller scenarios and the cooperation between them. Hence Central.

•  Why playground? Why not PoC?
  • A PoC is often a snapshot in time and often specific in scope. Playground suggests greater flexibility. The central service, the lego, is intended to be flexible and evolving. Similarly with what it is combined with to illustrate Covesa concepts and technology.
  • Patterns such as view/controller, out of the box data servers, application stores etc are well known. The Service could in part be defined by what's not known, by open questions, in next-gen architectures such as data-centric architectures, that needs to be tackled down. The Playground is the means to doing that and illustrating the results.
