J-STAGE

Largest Scientific and Technical Electronic Journal Platform in Japan

1,600 journals (2.3 million articles)

All abstracts are free.
More than 80 percent of full texts are free.
-Please read the access policy on the site before using contents on J-STAGE.
Department of Databases for Information and Knowledge InfrastructureJAPAN SCIENCE AND TECHNOLOGY AGENCY (JST)3

All journals on J-STAGE are…
1. Peer-reviewed journals published by Japanese
noncommercial societies, whose offices are located inJapan (joint publication with foreign publishers may beacceptable).
2. Journals should be published regularly.
3. Journals should accept papers contributed not only bysociety members but by nonmembers as well.

4. The society should bear the cost of data (full-text PDF
or XML, bibliographic XML data, etc.) production andmonitor the quality of uploaded data.

1.Conceptual stage• Background– Lower rate of digitalization than U.S. and Europe– Lack of mechanism for stable distribution of digital content– Need for improved visibility of Japanese-language literature• AimsTo organize and manage centrally the location informationof the scholarly content possessed in digital format byinstitutions throughout Japan, and to achieve interlinking
between these and with the main scholarly content outside
Japan, thereby strengthening communication of Japan’sscholarly information.
Department of Databases for Information and Knowledge InfrastructureJAPAN SCIENCE AND TECHNOLOGY AGENCY (JST)14

1.Conceptual stage• Main views offered– Should become a DOI Registration Agency– Important to link up with CrossRef– Clearly demarcate basic functions from additional services

Basic functions include means for assigning ID to content andregistering, and means for reaching the content reliably.
– What to do when multiple objects exist for the same content– Approach the project by gaining some idea of the scope, i.e., howmany journals and how many repositories

Domestic institutions work together to perform central functions using
DOI to promote management and distribution of digital content.

2. What is DOI?
The DOI Management Organization
The International DOI Foundation (IDF)•••

DOI resolution(http://dx.doi.org/XXX ⇒ URL with DOI in place of XXX)Management of DOI registration agencies (RA)Policy making

DOI Registration
Agencies (RA)• Administration of system infrastructure for DOI registration• Management of DOI registrants(those to whom DOIs are assigned)• Promoting wider use of the DOI system• There are 10 RA throughout the world, such as CrossRef.
＃In March 2012, JaLC was certified as the world’s 9th RA.
Department of Databases for Information and Knowledge InfrastructureJAPAN SCIENCE AND TECHNOLOGY AGENCY (JST)16

3. What is the Japan Link Center (JaLC)?
About the Japan Link Center (JaLC)•The JaLC is the only Japanese organization (and the 9th in the world)
authorized by the IDF as a Registration Agency (RA) for DOI•DOIs are assigned to various digital content including scholarly papers,
books, information associated with papers, patents, and research data,
and are managed along with the content location (URL).

•Administered jointly by academic institutions in Japan.

3. What is the Japan Link Center (JaLC)?
Advantages of participation in JaLC (for each kind of potential user)(a) Authors of academic papers• Easier for others to access the paper• Find out who cites the paper(b) Readers of academic papers• Are assured of finding their way to the paper itself• Can find the texts of cited references(c) Publishers• Easier to draw customers to their own website• Can readily identify cited references(d) Secondary database providers• Can reliably link to primary data location by means of DOI(e) Organizations distributing research funds• Can readily keep track of the publication status of papers byfunded researchers and citations of the papers, which is useful
information for assessment of the research

4. Ongoing JaLC Development
Improvement issues (growing demand):•Content that can be registered– Currently categories are provided only for bibliographic information for journal
papers, so journals, proceedings, survey reports, and dissertations arecovered.
– There is a need to assign DOI to books, research data, websites, patents andmany other kinds of content.

•Support for identical bibliographies– What about support for when the same content is located in multiple places?
– When bibliographies are the same but the contents are different
E.g.: Support for author versions, translations, etc.

• Support for interfaces– Supported formats and interfaces, etc., are limited while the metadata
coming from each organization are many and varied.
