Contributor: Ritsuko Nakajima, Takafumi Kato,Japan Science and Technology Agency (JST)1

Japan Link Center (JaLC)• Founded in March 2012
• Aimed to register DOIs for academic contents produced
in Japan or in Japanese, to circulate information in Japan and overseas.
• Controlled by four national organizations: Japan Science and Technology Agency (JST)(has 915 associate members) National Institute for Materials Science (NIMS) National Institute of Informatics (NII)(will have about 1,000 associate members) National Diet Library (NDL)• Operated by JST• Membership system
19 Regular members(Academic societies, Publishers, University libraries, etc)

• External coordination
JaLC is a member of CrossRef and DataCite(Mar. 2014)2

Upcoming features
JaLC will release new features in December 2014.
a. More content categories
Expanded to research data and books etc. besides journal articles.
JaLC will collaborate with DataCite in registering DOI for research data.

b. Edition information
Variation: publication version, author’s version, ...
Version : 1.0, 2.1, ...
Format: XML, PDF, …

c. Multiple resolution
Identical contents are resolved into original sites, archive sites and distributers' sites.

d. Researcher identifiers
ORCID, KAKEN ID, NDL authority ID are included in JaLC's deposit schema.
Ex. of application: Send pairs of ORCID and DOI to ORCID system so that corresponding articles will
be suggested as research results on ORCID service.

e. Linked data
Metadata are provided as linked data.

to register DOIs for Research Data
• Goal− Establish operation flows to register DOIs for research dataand have stable operation• Objectives− Set policies in registering DOIs for research data
− Establish operation flows to register DOIs for research datawith the next version of JaLC system. Ensure that byperforming registration tests

to register DOIs for Research Data
• Current Members• National Bioscience Database Center (NBDC), Japan Science andTechnology Agency (JST)• National Institute of Polar Research (NIPR)• National Institute of Informatics (NII)• National Institute of Informatics (NII)• Japan Agency for Marine-Earth Science and Technology (JAMSTEC)• Institute of Industrial Science, The University of Tokyo• Center for Spatial Information Science, The University of Tokyo• National Institute of Advanced Industrial Science and Technology (AIST)• National Institute of Information and Communication Technology(NICT)• Data Analysis Center for Geomagnetism and Space Magnetism, Kyoto
University• Library, Chiba University• National Institute for Materials Science (NIMS)• Riken Brain Science Institute11Summary• JaLC is established to enhance scientific communication with DOI• Ideally support all activities by researchers• JaLC started service for journal articles, then will extend it for books,e-learning, and data.
• Need of knowledge and experience about data registration• Start the experiment in Fall.
• Need for collaboration and coordination with DataCite
