[MGI23-P04] Current Open Science Activities for Research Data at JAMSTEC
-Findability of research data
Minting data Digital Object Identifier (DOI) to research data has been started to improve its findability. Earlier targets for minting data DOI are research cruise and dive information, observation data, cruise report, and dataset created by researchers published in JAMSTEC database for a long period of time. We are developing a Data DOI Management System and considering a sustainable workflow to mint and maintain DOI metadata.
-Interoperability of research data
Automatic linkage between JAMSTEC Data Catalog  and GeossPortal  has started to promote reuse data in the global geoscience community. About 50 metadata of JAMSTEC Data Catalog are searchable at GeossPortal by metadata harvesting as of February 2018.
The common key points for the both activities are appropriate metadata management, effective use of existing databases, and efficient linkage between data systems inside/outside the organization with limited manpower and system resources. Based on above our experiences, constrains and future prospects toward open science will be discussed.
