The 5th Tractus-X Community Days took place in Stuttgart from 4 to 5 December 2025 - a key annual highlight for all organisations, developers and experts in the field of open data spaces and the future of collaborative value creation.

Amidst numerous exciting presentations and sessions, Ingolf Gehrhardt from the Chair of Information Management and Tobias Kutzler from the Fraunhofer IFF showed how traceability could be realised in the semiconductor industry and beyond in various data spaces with their workshop "Traceability in Semiconductor-X and cross dataspaces".

The workshop clearly illustrated the special features of traceability in the semiconductor manufacturing supply chain, for example in comparison to the automotive industry. This was followed by lively discussions about the current status of cross-dataspaces and possible implementation paths - a lively dialogue to which numerous participants made valuable contributions.

As a representative of the developer panel, Ingolf gave personal insights into his experiences within the TractusX open source community and highlighted both the opportunities and challenges of an open developer community.

Special thanks go to the sponsors and especially Arena2036, who made the event possible under excellent conditions. The event not only demonstrated the aspiration to further develop Tractus-X as a technical basis for sovereign data spaces, but also as a lively community.

We look forward to continuing the ideas developed in the workshop together and to the Community Days 2026.
