On November 26, 2025, the Chair of  Computing in Engineering hosted a mini-symposium followed by a workshop on circularity and data spaces. The event was organized by the research team of subproject C01 in the Collaborative Research Center 1683 and brought together researchers from Eindhoven University of Technology and the Ruhr University Bochum to discuss current developments in digital ecosystems, material passports, ontologies, and data-driven approaches to circular construction.

Ekaterina Petrova (representing her doctoral student Krista van Zanderwijk) kicked off the event by presenting the UPSCALE project and highlighting the challenges of fragmented and non-standardized material supply chains. Julia Kaltenegger then provided insights into multimodal data prediction for existing buildings. In the third presentation, Avinash Ramachandruni introduced “Project Wilson” and explained information flows in a minimal viable dataspace.
In addition, Philipp Hagedorn (RUB, CRC 1683) gave an overview of subproject C01 and the digital ecosystem being developed in the CRC.
In the afternoon, thematic working groups deepened the exchange between participants on ontologies for material properties, digital ecosystems, and data spaces, as well as data requirements for circular construction.
