For each property, the respective dataset is aggregated with experimental data coming from the Materials Platform for Data Science (MPDS) , retrieved by using the provided API. MPDS is one of the largest resources currently available for material scientists. It leverages the extensive data available in the Pauling File , a comprehensive database of materials information reporting crystal structures chemical compositions and phase diagrams, to enable efficient exploration, analysis, and modeling of materials. For the two calculated datasets, we also consider the aggregation with calculated data from the Materials Project (MP) database .
