Overview of the NII Research Data Cloud

As an infrastructure to support research data's lifecycle, we started developing the NII Research Data Cloud (NII RDC) in 2017. The NII RDC consists of a data management platform (GakuNin RDM), a publication platform (WEKO3), and a discovery platform (CiNii Research), and move on to the production operation in 2021.

Research Data Infrastructure

NII RDC continuously expands its functionalities to enhance further usability. The data governance function orchestrates the existing three platforms and connects each other. The secure analysis function provides data analysis tools efficiently utilized from GakuNin RDM and then publishes a package consist of source code and data to WEKO3. The data curation function supports describing qualified metadata to realize FAIR principle-based data publication. To maximize these advanced functions' potential, data capacity building for researchers and research supporters is tremendously essential. We are also preparing an educational platform for this purpose. Not only the research domains which are relatively familiar with IT service, but our service aims to cover wide range of them including humanities and social sciences.

Research Data Infrastructure

GakuNin RDM (Research Data Management Platform)

GakuNin RDM is a research data management platform that provides an environment within which individual researchers or research groups can manage their research data and relevant files during a research project. It works in a closed setting where files can be version and access controlled among project members. File modifications will be tracked and long-term preservation will be provided for research integrity purposes.

WEKO3 (Publication Platform)

WEKO3 is a publication platform for researchers to publish research papers and data with related materials online that they decide to publish. It has the functions necessary to publish these research outputs, such as customizable ingest workflow and flexible metadata editor. WEKO3 is designed for JAIRO Cloud. JAIRO Cloud is a cloud service that provides institutional repository services for research institutions. JAIRO Cloud is a joint operation between JPCOAR and NII. In cooperation with GakuNin RDM, researchers can publish their research output in their institutional repositories by simple processes.

CiNii Research (Discovery Platform)

CiNii Research (search platform) is the largest academic information search service in Japan. It allows users to search not only for research results and articles registered in the public infrastructure but also for books, research data, researchers who produced those results, and information on research projects. This academic information forms a large knowledge graph internally and responds to researchers' various means of discovery, producing nimble operations and deep insights. Along with CiNii, the academic information navigator that has been provided by NII so far, it provides a function to explore the whole picture of academic activities.

Computational Services

The NII RDC Computational Services enable a researcher to create a package that contains his/her data processing program together with its execution environment so that it can be easily reused by other researchers or students. The package is stored in GakuNin RDM and shared within a group, or publicated in WEKO3 or GitHub and made available to other researchers. This will allow us to easily reproduce the analysis methods of previous studies and immediately start advanced research on top of them.

Human Resource Development

To effectively promote open science, it is important to develop systems and human resources for research data management. The Gakunin LMS is an educational platform that provides research data management materials that can be studied at each institution as a platform for sharing educational materials and content and provides a learning environment that allows each institution to check its learners' status. The educational materials handled by Gakunin LMS are reorganized as video content based on the educational materials "Design and Practice of Research Data Management Services" and "Research Data Management for Researchers" created by the Japan Public Corporation for Open Access Repositories (JPCOAR).

Data Governance Platform

The NII DMP System (tentative name) is a research data governance infrastructure for systematic planning, execution, and monitoring of research data management. Data governance is the control (planning, execution, and monitoring) of how research data is produced, stored, and used as an organization's intellectual asset. It enables researchers to automatically set up a research data environment using other infrastructures of the NII RDC according to their planning scheme. It also allows organizations to monitor the status of research data management and use it for compliance checks.

Data Curation System

The data curation system under consideration for RCOS, while also collaborating with GakuNin RDM and WEKO3, will realize an external collaboration system for data curation by providing a human network infrastructure for data curators in various fields belonging to inter-university research institutions and research organizations and support staff from university libraries and other institutions. Institutions participating in the network will be able to conduct data curation through this system, even in fields for which they do not have appropriate data curators. This will free researchers from the particularly burdensome task of publishing research data and create an environment in which they can concentrate on their research.

Open Access Promotion Services

Open Access Promotion Services notify institutional repositories of information about articles by affiliated researchers, along with the journals' archiving policies that contain the articles. With this notification, institutional repository staff can easily check whether the articles can be made open access in institutional repository, thereby promoting open access effectively.

Social Sciences and Humanities

In recent years, while open access to research data and articles has been encouraged, clarification of digital content's rights and protection of personal information has become increasingly important. In the humanities and social sciences, where human activities are the subject, many research contents are difficult to publish due to licensing, confidentiality, and privacy information.
