|TUBPL03||Experimental Data Transfer System BENTEN at SPring-8||702|
Recently, there are strong demands on open data to promote data science like material informatics. At SPring-8, we have been operated data transfer system for open data of XAFS measurements since 2013* with the second in the world for amount data**. However, it was difficult to satisfy demands such as generic uses in experimental stations and data federation with other facilities. To overcome these, we newly developed data transfer system BENTEN. BENTEN provides easy-to-use and unified interface with REST API for data access from both inside and outside SPring-8. At SPring-8, proposal number is assigned for each experiment and members in the proposal are defined in DB. BENTEN can also realize restricted data access with the members using authentication and the DB. Data registration was performed with metadata such as experimental conditions and samples. Various metadata in the experiments can be easily defined. To achieve flexible data access with full-text search, we used Elasticsearch as metadata store. We began operation of BENTEN and open access of XAFS data since March this year. We plan to utilize BENTEN to promote open data and data science also with other experimental data.
