The materials informatics unites computer, materials, and data sciences. The Materials Platform for Data Science (MPDS) is an online database of the PAULING FILE project, one of the oldest materials informatics initiatives. Since 1993 our international team manually curates the materials data, extracting them from scientific articles, books, proceedings, etc. All the data are of very high quality and back up such commercial products as Springer Materials and MedeA Materials Design. Herewith we present an open subset of these data in machine-readable formats: cell parameters vs. temperature and pressure diagrams, silver-potassium compounds data, binary oxides data, in-house MPDS machine-learning data, etc. We release these data under the CC BY 4.0 license.
