  1. Integration of Disciplinary Repository, Institutional Repository and National Portal NAMIKI Takao*, HORIKOSHI Kunie, SUZUKI Masako , SUGITA Shigeki**, KIKUCHI Mitsushi, OJIRO Koichi*** * Faculty of Science, Hokkaido University ** University Library, Hokkaido University *** National Institute of Informatics

  2. We are • Hokkaido University, JAPAN • 2,100 researchers and17,500 students • Disciplinary repository • The Sea of Mathematics (Faculty of Science) • Institutional repository • HUSCAP (University Library) • National Institute of Informatics, JAPAN • National portal “JuNii” for IRs in Japan

  3. HUSCAPhttp://eprints.lib.hokudai.ac.jp • Institutional repository • Hokkaido University Collection of Scholarly and Academic Papers • Journal articles • Proceedings • Learning objects • Since Jul. 2005 • 200 OA materials

  4. HUSCAP (continued) • Dspace 1.2.2 • CJK searchable for fulltext of assets • Japanization How-to by SUZUKI Keiji (http://www12.ocn.ne.jp/~zuki/Japanization/) • 2 metadata schema • oai_dc • junii (Original DC Application Profile defined by National Institute of Informatics) • NDC (‘Nippon Decimal Classification’ like DDC) • Original dc:type vocabulary • Research Output – Article • Research Output – Others

  5. The Sea of Mathematicshttp://eprints.math.sci.hokudai.ac.jphttp://coe.math.sci.hokudai.ac.jp • Disciplinary Repository • EPrints 2.2.1 • First 2 digits of Mathematics Subject Classification • As a Data Provider • Self-archiving by mathematicians • To write, print and advertise are our routine work • Preprint, Technical Report, Institutional Journal, Conference paper, Video, Software,....

  6. The Sea of Math. (continued) • As a Service Provider • Metadata Mirroring and Search (arXiv,EUCLID, NUMDAM,...) • Visualized Subject Correlation Map • http://metron.math.sci.hokudai.ac.jp/search-new/navi/jp/ • Selection by Classification • MSC XX-0X means Review or Educational articles • Mapping to Curriculum

  7. 2004 • Tohoku Math. J. • Nagoya Math. J. • Kodai Math. J. • Metadata: • projecteuclid.org

  8. 2005/10arXiv.org

  9. JuNii • National portal for Japanese scientific information • Comprehensive search of information on universities resource through metadata • JuNii’s backend database includes metadata harvested from institutional repositories in Japan • Total number of metadata stored: 80,000 (as of Nov. 2005)

  10. Harvesting framework • Metadata and Resource Harvesting from the Sea of Mathematics into HUSCAP • Archiving as a library collection • Metadata Harvesting from HUSCAP into JuNii JuNii The Sea of Mathematics metadata HUSCAP metadata resource

  11. The Sea of Mathematics: Co-operation with HUSCAP • Subject Conversion • HUSCAP uses Nippon Decimal Classification • Constructing Translation Table from MSC to NDC • Realized by Perl Subroutine in EPrints 2.2.1 which is called within oai-pmh support function • Embedding Full-Text URIs into dc:relation • Simple wget command • Problem: Non-HTTP protocol • Video --- Streaming Media

  12. HUSCAP: Metadata Harvesting from SoM • make-dspace-import-data.pl • To get other DP’s metadata and setup for ItemImport • Available at: http://www12.ocn.ne.jp/~zuki/Japanization/make-import.html (in Japanese Only)

  13. HUSCAP: Resource Harvesting from SoM • Adding codes to make-dspace-import-data.pl • “wget -nd -np -r -q [identifier_uri]” • Check previous log (correspondence table of OAI Identifier of SoM and DSpace handle) • Store into two directories (new / update) • ‘deleted’ records -> manually check and withdraw

  14. HUSCAP: ItemImport • In the two (new / update) directories, • dsrun org.dspace.app.itemimport.ItemImport --add / replace--eperson=xxx@zzz.hokudai.ac.jp--collection=230--source=importDIR--mapfile=mapfile / mapfile.update

  15. HUSCAP: as a Data Provider for JuNii • JUNIICrosswalk.java • http://ju.nii.ac.jp/oai/junii.xsd • University ID Number • DSpace resource type -> JuNii vocabulary • Ex. Article, Preprint, Thesis -> ‘Research Output – Articles’ • identifier xsi:type=“URL” • http://hdl.handle.net/2115/XXX • subject.ndc→subject xsi:type=“NDC”

  16. For researchers in Japan Conclusion JuNii For research community on mathematics and related discipline As the showcase of research activities in Hokkaido University HUSCAP The Sea of Mathematics
