Invitation to the 4th PMD Hackathon

We are pleased to invite you to the fourth PMD Hackathon on Semantic Interoperability, taking place from 18 to 20 November 2026 (“from Lunch to Lunch”) at BAM in Berlin (Steglitz).

Once again, the focus will be on the further development, extension, and improvement of the PMD Core Ontology (PMDco) as well as related topics and challenges. The hackathon provides an open platform for creative collaboration, in-depth discussions, and hands-on ontology engineering. Participants are explicitly encouraged to bring their own topics, questions, and challenges to discuss and work on together, drawing on the combined ontology expertise of the group. We look forward to engaged participants, inspiring discussions, and productive days together!
