As discussed in data architecture call May 21, this page shall serve as a collection of topics that we could discuss in an dedicated workshop session regarding next steps in CDSP after Berlin AMM 25.
Topic Collection:
| Nr | Title | Description | Expected Outcome in Workshop |
|---|---|---|---|
| 1 | Blueprint examples | How to make blue print example a bit more formal / user friendly https://github.com/COVESA/cdsp/tree/main/examples | |
| 2 | Showcase Spring AMM 26 (see as well table below) | As discussed at Berlin AMM one option would be to have a setup with real hardware including Cloud, ECU and Customer devices. Do we find Use Case that:

Topic Detailing:
Regarding workshop item 2 "Showcase Spring AMM 26":
The data architecture working group, as part of the preparations for the Showcase Spring AMM 26, agreed to systematically identify a suitable use case by first compiling a comprehensive list of aspects that a data-centric architecture use case should encompass. This collaborative effort will enable the group to prioritize the most valuable use case, especially in terms of how it can help the CDSP (Connected Data Services Platform) evolve and become a more valuable platform for all stakeholders who wish to experiment with or build upon the proposed architecture. This a first proposal, it is still work in progress.

Use Case proposals:
Use Case 1: Insurance (data semantics, possibly AI LLM and Semantic Reasoning)
Some possible aspects to be refined and mapped to the categories above:
- Data reduction before off-boarding (not specific to insurance).
- What: reduce size of data set or move result to higher DIKW level, e.g. info->knowledge
- How: conventional data processing, e.g. sampling, or AI.
- Biz view:
- Transmission cost reduction
- Reduction of processing and storage costs in cloud
- Privacy or IP concerns
- Use rules-based Semantic Reasoning to define business logic
- What:
- Use existing Knowledge Server functionality to implement insurance knowledge rules
- Show ability to update without changing underlying layers
- Technical growth potential:
- Implement subscription between Information Layer and DBs using DB functionality - currently IL polls.
- Optional: explore OSS reasoner
- Optional: explore patterns of how knowledge graph can be integrated with other data, e.g. timeseries, rather than use binary solutions, e.g. must use knowledge OR timeseries database.
- Use existing Knowledge Server functionality to implement insurance knowledge rules
- Biz view:
- Allow insurance companies to concentrate on 'value' via the rules independently of southbound systems
- What:
Use Case 2: Fuel management for fleet efficiency
Use Case 3: Predictive Maintenance
Use Case 4:
Use Case 5:
Stephen Lawrence It would be useful to ensure we have use-cases that utilize different categories of data. For example, an OEM app may mostly use VSS state/actuator data, e.g. HVAC or seating, that is low frequency and need low latency. Whilst a fleet or telematics use case such as maintenance or position may mostly use VSS timeseries data that is high frequency.
