It is my pleasure to nominate Johann Schütz (https://github.com/jSchuetz88) as a Committer on Eclipse Tractus-X Project (https://accounts.eclipse.org/users/jschuetz88).
Johann has been contributing to the Eclipse Tractus-X Project mainly on the domain of semantic modelling – a foundational pillar for the interoperability of the entire dataspace.
Semantic Layer & Aspect Modelling (sldt-semantic-models)
He is one of the most active contributors to the sldt‑semantic‑models repository, with over 40 pull requests covering creation, migration, deprecation, and automation tooling. His work includes critical updates for DPP, PCF, Battery Pass, TransmissionPass, Chemical Material Passport, and new models such as CBAM and the Simulated Week‑Based Material Demand and Capacity Group.
He has also improved the repository’s tooling and CI/CD by migrating the SAMM‑CLI from 2.9.5 to 2.11.1 (enabling SAMM 2.1 → 2.2), adding automated validation of imported models, creating a workflow to regenerate all artefacts, deprecating outdated models, and fixing namespaces and metadata.
Community Behaviour & Open Source Practice
Since August 2024, Johann has organized and moderated the weekly Semantic Model Modelling meetings, reviewing changes, discussing feedback, clarifying open points, supporting modelling topics and shared‑model questions, and ensuring consistency across models. His PRs are well‑scoped, follow milestone criteria, and he actively participates in reviews and discussions.
Elevating Johann to Committer status will formalize the influence he already exercises and give him the write access needed to maintain and review the semantic modelling repositories he has invested so much in.

| Mathias Brunkow Moser | +1 | I believed Johann was already a committer! Since a long time he is doing very good contributions, moderating the Semantic Modeling Office Hour, engaging on the Community Days with workshops and is there for the community. He is also actively taking care of the semantic models repo in Eclipse Tractus-X and making contributions to our website. His technical experience and knowledge in semantic modeling is a great asset for all of us! And his domain knowledge in Standardization is also very great for our KITs community. Well deserved! |

Johann has made significant contributions to the semantic models and is actively leading workshops within the Tractus-X community. Having Johann as a Committer would be a great asset for Tractus-X and, in my opinion, this recognition is long overdue. |
