DataCite Annual Conference, August 25, Nancy, France 1 Expanding the content categories at JaLC Hideaki Takeda Chair, Joint Steering Committee Japan Link Center (JaLC) http://japanlinkcenter.org/ Contributor: Ritsuko Nakajima, Takafumi Kato, Japan Science and Technology Agency (JST)
2 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 overse as. • 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)

5 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 wil col aborate 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 artic les will be suggested as research results on ORCID service. e. Linked data Metadata are provided as linked data.

10 Experiment Project to register DOIs for Research Data • Goal − Establish operation flows to register DOIs for research data and ha ve stable operation • Objectives − Set policies in registering DOIs for research data − Establish operation flows to register DOIs for research data with th e next version of JaLC system. Ensure that by performing registrati on tests
11 Project Organization Report <-Support Support -> Participants are supposed to be research institutes, universities, etc. and chosen by public invitation.
12 Examples of subjects to be examined • Flow of operations − In case a regular member deposits only its data − In case a regular member deposits their data and the associate me mbers’ data together • Persistent access − Can time-limited projects participate? Who wil ensure the persiste ncy of the data? (ex.) The representative institute takes over all of the data Registering DOIs only for data managed by real organizations among th e members of the project • Granularity of registration
13 Examples of subjects to be examined (cont’d) • Landing page − Metadata description page/file/… − For open/closed data • Other operations − Adding data after registration of DOI − Registering DOI for a large amount of data • Application − Citing DOIs for research data − Developing other applications

15 Multiple resolution <Deposit> JaLC DOI, URL(A), other metadata and Member A multiple resolution priority number [a] When JaLC detects the same DOIs deposited with multiple resolution priority number by <Deposit> different members, the DOI, URL(B), other metadata and multiple resolution Member B multiple resolution priority number [b] function works. JaLC multiple resolution works only among JaLC DOIs. CrossRef’s DOIs are out of coverage.
16 Summary • JaLC is established to enhance scientific communication with DOI • Ideal y support al activities by researchers • JaLC started service for journal articles, then wil extend it for books, e-learning, and data. • Need of knowledge and experience about data registratio n • Start the experiment in Fal . • Need for col aboration and coordination with DataCite
