This session is intended to advance discussion of a community led reference implementation of a Central Data Service playground. The session will be split into two parts Part 1: Readout of the proposal as a starting point for discussion and to build understanding (9:30-9:45/50) Part 2: Workshop the base components and the possibilities for 'spins' using it, e.g: Data models: knowledge layer, data models, VSSo Interface pillar: IFEX, service definition, Vehicle API/Autosar Data Architecture: Sync, reasoning at the edge etc. Note: This is related to the BMW/MongoDB session above. The topic is an evolution towards a public reference playground as previously discussed in the Spring AMM in Porto and the Data Architecture and Infrastructure pillar.
