Japan Link Center(JaLC)
The Japan Link Center (JaLC) is the only organization in Japan accredited by the DOI Foundation
as a Registration Agencies (RA) for the global identifier DOI.
JaLC registers DOIs for various content including scholarly papers, books, research data, etc.,
and manages them with the location information (URL) of the contents.
JaLC is jointly operated by four governmental institutions in Japan.

"Guidelines for Registering DOIs for Research Data"(June 3, 2024)

"Guidelines for Registering DOIs for Research Data"(June 3, 2024)
https://doi.org/10.11502/rd_guideline_2e_en

Published by
Subcommittee for Promoting for Subcommittee, RDUF (Research Data Utilization Forum)
Japan Link Center

These guidelines provided a wide range of easy-to-understand explanations related to DOI registration such as the basic information about JaLC and DOIs, the concept of registering DOIs for research data, the procedures for registering DOIs and so on.

Although the Guidelines were created for those who are considering registering DOIs for research data through JaLC, much of the content can be common with DOIs other than JaLC and will be useful to many readers who are considering registering DOIs for research data.

Major revisions from the 2015 edition include the following;

  • The main intended readers have been classified as (1) Managers of organizations and institutions, (2) Practitioners, and (3) Researchers and data creators, and the intended readers for each chapter have been clearly indicated.

  • A new chapter, "3. Policy on DOI registration for research data," was added. This chapter describes the significance of DOI registration as a foundation that supports the FAIR principle, and how to use DOIs registered for research data corresponding to research phases such as "data citation" and "data management."

  • Expanded case studies of DOI registration and use for research data in research institutions. The case studies introduce examples of DOI registration and utilization in diverse fields such as life sciences, environmental studies, materials science, and humanities.
  • About JaLC

    What's Japan Link Center(JaLC) ?

    Japan Link Center (JaLC) is a DOI Registration Agency (RA) that was accredited by the DOI Foundation on March 15, 2012. JaLC is jointly operated by the Japan Science and Technology Agency (JST), the National Institute for Materials Science (NIMS), the National Institute of Informatics (NII), and the National Diet Library (NDL).

    About DOI Registration Agencies (RA) please refer to the web site of the DOI Foundation.

    Overview of JaLC

    JaLC aims to improve the convenience of domestic and overseas information services in Japan and promote the international distribution of domestic scholarly academic content produced in Japan or in Japanese by centrally managing bibliographic and location information on electronic scholarly academic content (journal articles, dissertations, books and reports, research data, e-learning, etc.) owned by domestic organizations and registering DOIs. As an RA, JaLC provides DOI registration services to JaLC members.

    JaLC members are divided into two categories, "Regular Members" and "Associate Members," each with different details of services available to them. Regular Members can register DOIs directly with JaLC, whereas Associate Members register DOIs with JaLC through Regular Members. JaLC assigns one or more unique prefixes to each Regular Member and Associate Member depending on the purpose.

    JaLC is an RA and a member of Crossref and DataCite. In addition to DOIs assigned by JaLC, JaLC members can also register DOIs assigned by Crossref and DataCite via JaLC (both require an additional fee).

    JaLC metadata

    JaLC defines metadata for each type of content, with different metadata schemas for journal articles, dissertations, books and reports, research data, e-learning, etc.

    The metadata schema for research data corresponds to the DataCite schema (DataCite Metadata Schema 4.4)*1 (as of March 2024). DataCite aims to advance scientific research by providing researchers with a way to locate, identify, and cite research data, and it has defined a metadata schema to ensure that resources can be cited and retrieved accurately and consistently. Only some properties are mandatory, such as Identifier, Creator, Title, Publisher, Publication Year, etc., which are necessary for citation, to maintain compatibility with schemas in many fields. However, to make data more easily retrievable and citable, recommended and optional properties have been defined in addition to the mandatory properties.*2

    JaLC's metadata and metadata schema for research data are based on DataCite definitions, but to align the metadata and items with those of other content types (journal articles, etc.) that are subject to DOI registration, changes have been made to the DataCite definitions, such as how tags are named, how they are handled in multiple languages, and the addition of funding information. Additionally, items have been added to accommodate the common metadata items (as of March 31, 2023) defined in the "Basic Approach to the Management and Utilization of Publicly Funded Research Data" (Council for Promotion of Integrated Innovation Strategy, April 2021) *3.
