Short intro: MPDS (www.mpds.io) is an online materials database known as PAULING FILE project with nearly 2 million entries, manually excerpted from peer-reviewed literature. The data are available via REST API in CIF and JSON formats. Since 1993 almost 270 000 publications have been processed, resulting in more than 400 000 crystalline structures, about 60 000 phase diagrams and 800 000 physical property sets, interlinked with more than 100 000 distinct materials phases. There are thousands of publications referring PAULING FILE: https://scholar.google.com/scholar?q=PAULING+FILE

We introduce rather simple yet powerful machine-learning technique able to predict physical properties from the only crystalline structure. So far the isothermal bulk modulus, enthalpy of formation, heat capacity, and melting temperature can be predicted with quite good accuracy. All the code is open-source. Just upload CIF or POSCAR at https://mpds.io/ml

We have opened some parts of the PAULING FILE dataset under CC BY 4.0 license. These are all diagrams of cell parameters vs. temperature/pressure, all binary oxides, and all silver-potassium compounds. These data are freely available online in CIF or JSON formats.
