本コレクションデータは、X線吸収微細構造(X-ray Absorption Fine Structure, XAFS)スペクトルの広い利用を目的に、関係機関のご協力の下、国立研究開発法人物質・材料研究機構(NIMS)にて編纂したものです。

  • 公益財団法人 高輝度光科学研究センター

 関係機関から提供された「物質」及び「測定」に関するメタデータは、データプラットフォーム(DPF)におけるデータ連携に適した形式に編纂されて、システム上の表示・検索に使われています。「物質」についてはID(Q番号)を付与して語彙分類して管理しています。 システムで使用しているメタデータは RDEmetainfo.xml のファイル名で収録されています。

文例: 本研究では、MDR XAFS DB [1] で公開されているデータを使用しました。

 This collection of data has been compiled at the National Institute for Materials Science (NIMS) with the cooperation of related organizations for the purpose of wide use of X-ray Absorption Fine Structure (XAFS) spectra.
 The data published in this data collection are publicly known data, and the data providers have guaranteed that the publication of the data does not violate the Copyright Law, the Personal Information Protection Law, or any other laws and regulations by submitting the "Application for Data Publication in the Materials Data Repository (MDR)".
The data providers as of April 2021 are as follows.

  • Japan Synchrotron Radiation Research Institute

 The data published in this repository can be used to determine the electronic state and local structure of materials. For details of analysis methods, please refer to the many references available.
 Information on substances and measurements is compiled from metadata provided by relevant organizations into a format suitable for data linkage on the Data Platform (DPF), and used for display and search. For substances, IDs (Q numbers) are assigned, and the substances are classified and managed in a dictionary. The metadata used in the system is contained in the file name RDEmetainfo.xml.
 The metadata provided by the related organizations can be downloaded in three different formats depending on the purpose of use.
tsv format: Converted to a flat Key-Value format that is easy to display in MDRs and spreadsheets.
json format: A hierarchical structure expressed in a format suitable for organizing data in a machine.
yaml format: A hierarchical structure expressed in paragraphs, etc., that is easier for people to read than json format.

 In principle, the license for the data listed here is "Attribution-NonCommercial-ShareAlike" (the data may be used under the conditions that the source is clearly indicated, the data is used for noncommercial purposes, and the same terms of use elements as the original data are given). If you wish to cite the data in an academic paper, please indicate the source clearly.
(Example) In this study, we used the data published in MDR XAFS DB [1].
