ARIM-mdx data system
Information system for data collection, management and analysis
All users of the University of Tokyo's Materials Advanced Research Infrastructure areARIM-mdx data systemBy using this data system, the following becomes possible:
- Private with cloud storageLarge data storage
- between collaboratorsData sharing,Open to the publicflexible management of
- Efficient and secureDirect data transfer
- With interactive programming environment and Remote DesktopData 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.
1. Large scale cloud storage (Nextcloud)
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.

2. IoT devices for direct data transfer from experimental equipment to the cloud
It is possible to transfer data directly from experimental equipment to large-scale cloud storage using IoT devices.The data is transferred separately to folders for each project.

3. Remote programming and data analysis environment (Jupyter / VSCode / Remote Desktop)
Data stored in large-scale cloud storage can be analyzed interactively using mdx's computational resources (Jupyter), full-scale software development (VS Code) or data analysis via remote desktop.

Participation and cooperation in data provision and registration
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) will be important.
