Piddiplatsch

Piddiplatsch consumes ESGF STAC publication records from Kafka and registers persistent identifiers with the Handle System. Its staged workflow is harvest → map + validation → publish, with JSONL files between stages.

• Installation and quick start
• Architecture: routing, project plugins, and processing stages.
• Configuration: site settings and supported options.
• Operations: output, publication, retries, and monitoring.
• Recovery & retry: advanced recovery procedures.
• Deployment: Linux service setup with Ansible.

About the project

Piddiplatsch is developed for the ESGF community and used in production at DKRZ. It supports sites managing CMIP dataset and file records, with built-in plugins for CMIP6, CMIP6Plus, CMIP7, and CORDEX-CMIP6. Contributions from other ESGF sites and organizations with similar workflows are welcome.

The name is inspired by the TV puppet Pittiplatsch, with a phonetic PID pun and the short CLI name piddi: curious by nature, persistent by design.
