Materials Data Repository

Materials Data Repository

A data repository that hosts materials research data and publications. Discover various data and publications using metadata tailored for materials.


Publishing research achievements has been done through papers and conference presentations, but recently it has become commonplace to publish data to support the papers or just data by themselves. This allows for wider use of research achievements.

The Materials Data Repository (MDR) is a repository to collect and host not only papers and presentations, but also materials data, providing them for use in further materials research and materials informatics. Users can discover publications and datasets using metadata tailored for materials or by a full-text search, and can view and download them.
