Authors & Contributors

The Sustainability Transformation HaCLAthon is a collaborative, open-science initiative. Unlike traditional conference proceedings that separate authors into isolated papers, this living Jupyter Book is a shared, citable data artifact (Behnisch et al. 2026).

Every accepted contributor is recognized as a co-author of the final published publication with a permanent DOI.

Contribution & Recognition Model

We follow the open-science principles of the CRediT (Contributor Roles Taxonomy) to acknowledge all forms of scholarly work transparently:

• 💻 Code & Software: Developing computational workflows, Python/R scripts, and spatial analysis pipelines.

• 🗺️ Data Stories & Visualization: Authoring map-led narratives, Carto-Lab experiments, and visual interpretations.

• ✍️ Writing & Conceptualization: Drafting domain texts, defining planning problems, and formulating policy relevance.

• 📦 Data Curation & Testing: Providing replication packages, preparing OGC/API datasets, and auditing cloud execution.

• ⚙️ Infrastructure & Facilitation: Maintaining CI/CD deployment, Jupyter4NFDI/Colab integration, and Git repository curation.

How Authorship is Tracked

1. Git Commit History: Every commit merged into main preserves the author’s original Git name, email, and GitHub account attribution.

2. Chapter Metadata: Each chapter explicitly lists its primary contributing authors at the top of the notebook.

3. CITATION.cff: Before final publication (October 2026), all contributors will be compiled into the repository’s machine-readable CITATION.cff file and registered in the Zenodo / ioerDATA DOI metadata.
