Common metadata schemas, API frameworks,and policies are being developed to allow integration between heterogeneous systems.�� � ��02 0 1  �      ��       Research Data Management !"#" RepositoryLoginuser !"password        !"# "ortal My page• Data Repository• Research Data Management   • Data Collection System   • SIP-MISystem • Machine Learning Datasets!"#" Collection System!echanical Characteristic DB• Mechanical Characteristic DB!"#$%" !ystem !"# $latform %!"# Visualizer!"chine Learning Datasets!ubsystem "#!ubsystem "# (under active development)!"  Single Sign-On #$!"  #ata Relaying!"
