Information system for data collection, management and analysis

All facility users of the University of Tokyo Materials Advanced Research Infrastructure can use the ARIM-mdx data system.By using this data system, you will be able to:

• Private with cloud storageLarge data storage
• between collaboratorsData sharing,Open to the publicflexible management of
• Efficient and secureDirect data transfer
• through an interactive programming environmentData analysis and software development
• Data provision/registrationby,Wide area data sharing service (NIMS RDE) implemented by 25 organizations nationwideto participate in

This system consists of the following three services, and is jointly operated by 3 domestic organizations.academic cloud system mdx Built on top.

All facility users for each projectUp to 30TB cloud storageis available.An open source cloud storage systemNextcloudto access the ultra-large storage area of ​​mdx.

Regarding projects that have applied for data provision and registration,

• Data in large-scale cloud storageFiltering based on equipment used and date of useThis information will be checked against the contents of the usage report.the result,Identify data to be provided/registeredWill be
• Corresponding provision/registration dataAutomatically by this system after notification to the project managerNIMS RDE systemTransfer and register toWill be
• The transferred data will be available from the beginning of the next fiscal year after the facility usage year.It will not be used or viewed for 2 years (non-shared period, can be extended for up to 1 year) .
• After a non-sharing period,NIMS RDE systemavailable for general use (wide area share)It will be.
