Joint research project Fluid 4.0: Hackathon No. II in Dresden

On March 11 and 12, 2025, the second hackathon took place as part of the Fluid 4.0 joint research project. The aim was to make practical progress in the areas of asset administration shells, data rooms and client-server applications.

Day 1: Modeling asset administration shells

The first day was dedicated to the modeling of Asset Administration Shells (AAS). Using the AAS Designer provided by our associated partner Meta-Level, we were able to model our demonstrators and systems. We developed:

• New approaches for mapping characteristiccurves (design of the "Characteristic Curve" submodel),
• Extensions for the AID (Asset Interface Description) submodel to describe CAN interfaces.

Many thanks to Christina Bornträger for her on-site support.

Day 2: Data rooms and client-server applications

On the second day we split into two groups:

• Group 1: Data rooms
  • Introduction to the topic by Shubham Thakkar from Smart Systems Hub Dresden.
  • Use of the Tractus-X implementation of the Smart Systems Hub to create a demo environment for Fluid 4.0.
  • First proof-of-concept for communication between data provider and consumer.
• Group 2: Client-server applications
  • Focus on the Basyx .NET SDK and the aas-core SDK.
  • Development of the first proof-of-concepts for project-related services using our project's own AAS repository.

Conclusion and outlook

At the end, we reflected on our progress and collected ideas for the next hackathon. Everyone agreed that this format offers enormous added value for the development work in the project.

Some of these results will also be incorporated directly into our demonstrators at Hannover Messe 25. It's worth stopping by: http: //fluid40.de/specialshow/
