Description:

The NIMS Materials Data Repository (NIMS MDR, https://mdr.nims.go.jp) is a data repository that provides articles and materials research datasets hosted by National Institute for Materials Science (NIMS). While it serves downloading research data files, it works in conjunction with other applications such as a data aggregation service and MatVoc (https://matvoc.nims.go.jp), a vocabulary service for materials science to create a materials data platform and disseminate datasets on NIMS MDR. This presentation will introduce the MDR XAFS DB (https://doi.org/10.48505/nims.1447) as an use case of a data platform linking datasets on NIMS MDR and vocabularies on MatVoc. It provides cross-searching XAFS (X-ray absorption fine structure) spectral data curated by research institutions in Japan. In addition, this presentation will introduce the International XAFS DB Portal (https://ixdb.jxafs.org/) built on several XAFS databases including MDR XAFS DB.
