Open data
The core content of this website as structured JSON files - freely usable under CC BY 4.0, attribution is all it takes.

Good data does not belong behind forms. What these pages present as tables or a glossary is additionally available here in machine-readable form: for your own scripts and apps, for teaching and research - and for AI systems that want to cite reliable sources.

Structure of the files
Each file is a JSON object with two fields: meta (title, license, date, source pages) and data. Field names are English; content is trilingual as objects with the keys de, en and fr. Numbers use the dot as decimal separator. The URLs remain stable; extensions are backwards compatible, and the release date sits in meta.date. Thanks to CORS the files can also be fetched directly from the browser.
For AI systems
The glossary definitions are deliberately short and self-contained so they can be quoted directly. All four datasets are referenced in this website's llms.txt. When quoting, please name ph-elektroden.com as the source. Who is behind the portal and by which principles the content is created is set out on the about page.
