This presentation introduces the outline and progress of the “Research Data Ecosystem Development Project,” led by the National Institute of Informatics (NII). The project aims to promote the appropriate management and utilization of research data through the development of various functions, such as data governance, data provenance, confidentiality analysis, and data curation, centered around the NII Research Data Cloud (NII RDC), a research data infrastructure developed by NII. In addition, the project supports the advancement of data-driven research using AI and machine learning while focusing on human resource development to enhance data literacy.

　Furthermore, this initiative seeks to disseminate the research data ecosystem nationwide through the “Research Data Start-up Support Project,” which targets regional research institutions. This forum focuses on social issues such as digitizing regional materials and preserving cultural heritage against disasters. The presentation will highlight the role of rapid data sharing and access in regional recovery, underscoring the importance of developing a sustainable research data ecosystem on a national scale.

　Earthquake archives and catalogs (chronologies) of historical earthquakes has been digitized as a result of historical earthquake research. Several research projects have already attempted to digitize them, and some of them have been developed into practical databases, and some of them have been released as open data. Most of the existing digital resources on historical earthquakes have been realized through collaboration among seismology, history, and informatics. Here databases related to Japanese historical earthquake research are reviewed. Development of databases and technologies should be incorporated in the future are also shown.

　In Japan, a wide variety of regional archives exist, and they are valuable cultural resources. However, a cross-regional data-sharing infrastructure, which will serve as a core for sustainable inheritance, has not yet been developed for the medium- to long-term collection, preservation, and publication of data that record information on these regional materials. The presenters have been working on the realization of a system to pass on regional material data to future generations through regional cooperation, mainly in the Yamagata and Okuaizu regions. This report outlines the concept.

　In order to discover the value of unused regional cultural resources that are disappearing in various regions and to pass them on as resources, it is necessary to informatize them into research data so that can be used. The authors conceived a solution to this problem by developing and operating a multiresource platform for co-creating research data and new value from underutilized regional cultural resources, forming a community with local residents, curators, and resource managers who have local cultural resources as well as experts, researchers, and interested citizens at remote sites. This paper describes the outline of the multi-resource platform and scheme of the project.

　In this lecture, we will talk about the rescue activities for regional materials damaged by the Noto Peninsula Earthquake that occurred on January 1, 2024, and the efforts of AMANE LLC, Wajima City, Ishikawa Prefecture, and the National Museum of Japanese History before the earthquake. I would like to report on my involvement with the historical material research I was conducting. In particular, we will discuss how information on local materials collected and recorded through a summary survey was utilized in the rescue of damaged materials.

　We are currently working on "Building a cross-regional data sharing infrastructure with the aim of inheriting and opening up regional material data." This project consists of two initiatives. The first is the construction of a shared storage for regional material data that transcends regions and organizations. The other is the creation of high-resolution images and 3D data for further future use, and the organization of issues regarding customs and related laws and regulations concerning the opening up of regional material data. In addition to these two points, this paper describes the concept of building a community for collaboration that transcends regions and organizations.

　Data publication is becoming an essential part of today's research activities. In some disciplines, data publication is a condition for submitting a paper, there are legal aspects such as international treaties that make it obligatory, so the construction of disciplinary repositories that promote the publication and utilization of research data is an urgent issue. In recent years, several research centers have been actively promoting the publication of research data, but even in the same field, data is not linked to each other, making it difficult to utilize. To solve this problem, we need a portal site for collaborative searches ”data catalogs”. In this poster presentation, we will report on the background to the implementation of ResourceSync, using the case of building a data catalog using WEKO3, which is being developed by the National Institute of Informatics, to organize the issues involved in linking with external repositories.

　The global movement toward open science is accelerating, with a focus on worldwide knowledge sharing. Researchers receiving public funding must manage and utilize research data under funder policies and the "open-and-close" strategy. This strategy seeks to balance international contributions with national interests, ensuring that research outcomes benefit both the global community and the home country. The responsibilities of researchers regarding research outputs, including research data, are on the rise, such as creating and implementing Data Management Plans in publicly funded projects and immediate open access to papers and evidence data. Given these increasing demands, infrastructure is critical to support researchers in managing, analyzing, sharing, and publishing research data. Effective data management practices are essential for reducing researchers' workload, allowing them to focus on their scientific contributions. This research presents the Comprehensive Pre-symptomatic Database Project as a case study, which aims to share, analyze, and publish experimental data, clinical data, and mathematical analysis data derived from mathematical analysis based on these datasets used in medicalmathematical collaborative research. This research outlines the challenges related to metadata processing in managing, sharing, analyzing, and publishing research data and discusses the necessary functionalities.

　In recent years, artificial intelligence technology has rapidly developed, with knowledge graphs, which represent human knowledge in a graph structure, gaining significant attention. These graphs are utilized as foundational technologies in various fields and tools. Knowledge graphs effectively integrate information from diverse data sources and clarify the relationships between them. This study proposes a method for managing disaster data in the preservation and inheritance of regional materials using knowledge graphs. By representing various past disaster events and their interrelations through a unified structure, knowledge graphs are expected to facilitate the integration of multiple sources of information, thereby enhancing data reuse and knowledge transfer. Furthermore, by visualizing the interrelationships between individual disaster data, this approach is anticipated to contribute to future disaster risk assessments and improve disaster response strategies.

The Web Archiving Project (WARP) of the National Diet Library began selectively collecting websites of public institutions in 2002, and in 2010, the National Diet Library Law was amended to allow for the regular collection and online publication of the websites of national organizations, independent administrative institutions, national university corporations, special corporations, etc., and local governments, including local public corporations. The National Diet Library has been regularly collecting and opening them on the Web. However, we reported that many local governments, such as prefectures and municipalities, do not open their past homepages collected by WARP to the Web. In this study, we report the results of a survey on the past homepages at national government agencies, independent administrative institutions, national university corporations, and special corporations whose past homepages are collected by WARP, in addition to local governments, and discuss measures for the Web disclosure of past homepages at all public institutions.

　While most universities require students to study mathematical and data science at the elementary level, the number of international students is increasing even in small liberal arts universities. In the face of language barriers, lack of prerequisite knowledge, and differences in educational curricula, we devised textbooks and lecture content to provide data science education to international students in the same way as Japanese students, and ascertained the status of knowledge acquisition by the students. As a result, it was shown that international students have the same level of understanding of data science as Japanese students.

　This paper introduces the learning management system "GakuNin LMS," designed to promote education and develop human resources in research data management. GakuNin LMS allows for easy sharing and customization of educational materials, and efficient learner management through the GakuNin academic authentication system. It also uses short video "micro-content materials" to provide a learning environment that meets the diverse needs of learners. By using this system, it is expected to help develop professionals in research data management and improve the efficiency and quality of research.

　In this presentation, we introduce and discuss “Mingu Web,” an application for collecting information on historical and cultural materials such as mingu. To solve the problem of preservation, succession, and utilization of regional mingu materials, the Academic Repository Network (Re*poN) is developing the “Mingu Web” application as a platform for collecting and sharing information on mingu materials. This application allows anyone to share and browse information on catalogs, bibliographies, and events, including exhibitions. The information to be shared can be incomplete; sharing only images or incomplete catalog information is acceptable. By lowering the hurdles to information sharing in this way, we aim to make more mingu materials discoverable and utilizable. We also envision that the application will contribute to the formation of a community for the collection and utilization of information on mingu by linking with existing public databases and by being used to collect information on materials and exhibitions at museums and other institutions.

　Kanazawa University was selected for the Advanced Research Infrastructure Sharing Project in FY2020 and developed an academic data management system named “ARCADE2” as part of a research data ecosystem. Built under the Kanazawa University Academic Data Management Policy, ARCADE2 aims to comprehensively manage research data and "academic data" from educational activities. Current improvements focus on adapting ARCADE2 for core facility environments and enhancing its architecture. By leveraging open-source software, the project aims to establish a cost-effective, flexible system that supports the research data ecosystem and enables broad use across various core facilities.

　In recent years, digital archives have been actively promoted as a means of preserving, accumulating, and passing on materials, as well as promoting their utilization. By disclosing information on materials and the institutions that hold them, it is possible to understand the existence of materials that may have been damaged after a natural disaster strikes. AMANE has been successively disclosing research and studies of regional materials since 2023 at AMANE Archives. AMANE Archives aims to collaborate with the local community through the sharing of a digital archiving environment. AMANE Archives currently has about 6,700 items on display, including materials from Wajima City, which suffered extensive damage in the Noto Peninsula earthquake of 2024. This paper discusses the relationship between possibly damaged materials and digital archives, and the social significance of local material archives, using AMANE Archives' role in providing information on materials in disaster areas after a disaster occurs as a case study.

In Japan, university faculty members are releasing educational materials such as video clips and documents they have created in their educational activities as Open Educational Resources (OER). In previous research, we collected the metadata of these OER automatically or manually and released the “OER Repository Trial Version” which enabled cross-searching of OER. However, the metadata of OER currently registered in the repository is limited to items such as titles and abstracts, and the collected metadata varies depending on the institution registering OER. Therefore, this study aims to establish a guideline to explain how to add metadata that can be easily retrieved as educational materials. In addition, we aimed to promote the understanding of OER itself by including the background and examples of OER in the guideline. In this presentation, we will give an overview of the guidelines we developed.

　The Okuaizu Digital Archive (Okuaizu DA) is a regional archive established by seven towns and villages in western Fukushima Prefecture, collaborating with local governments. This paper explores how the digital archive system can be used for citizen-participatory activities, focusing on a workshop designed to organize and preserve folk tools using the Okuaizu DA. This practical approach helped to clarify the basic procedures and challenges of utilizing a digital archive for community involvement in cultural preservation.
