Hydrology use case. (A) A hydrologic model, here represented by the logo of the mesoscale Hydrologic Model (mHM https://mhm-ufz.org, last access: 25 June 2024), creates output (i.e., hydrological variables shown by the blue cylinder) and additional metadata information (yellow cylinder). A hydrologic model simulates the water cycle at the land surface. A typical output variable is river discharge (m3s−1). Hydrological data is annotated by metadata post-processed by the Archivist. (B) Distribution of prediction performances of the hydrologic model across measurement stations for two parameter sets \({{\mathcal{P}}}_{1}\) and \({{\mathcal{P}}}_{2}\). Prediction performance is estimated by comparing simulated and observed river discharge for each measurement station. (C) Time series of observed (black) and predicted river discharge (red; parameter set \({{\mathcal{P}}}_{1}\)).
