Fostering Collaboration with Shareable and Standards-Compliant Workflows
Open Science Persistent Demonstrator is a long-term multi-stakeholder initiative to facilitate the creation and communication of reproducible Earth Science.
The second phase of the Open Science Persistent Demonstrator (OSPD) initiative began in 2025 and aimed to increase the transparency, reproducibility, and interoperability of research outputs. In total, there were four objectives:
- facilitate cross-platform reproducibility,
- enable reuse of workflows in other contexts with new data and a different parameters configuration,
- increase the interoperability of code and data,
- and provide documentation in a structured format.
To achieve these objectives, we aimed to identify existing workflows suitable for reuse, describe these workflows using open science ontologies, execute them on different platforms, and use building blocks to develop reusable schema components.
52°North contributed to facilitating the cross-platform reproducibility and the development of open science ontologies. Overall, the project runs for three years and consists of three phases.
