AIRway Project

• Launched 2006• Access Path to Institu

tional Resources via Link Resolvers

• Funded by NII (National Institute of Informatics, JAPAN

• Partners– Hokkaido University– Openly, OCLC– And,

– University of Tsukuba– Chiba University– Nagoya University– Kyushu Universtity– NII

Roadmap

• Phase 1 (May – Sep. 2006)– One IR and One Link Resolver

• Phase 2 (Oct. 2006 -)– Many IRs and Many Link Resolvers

HUSCAP

• Approximately 1,400 articles of Thomson-indexed journals– Many of them are

authors’ final drafts

• DSpace 1.3.2

Oct. 2006 Leeds, Cranfield and Bath 6

Users of HUSCAP

• From university web site• From Google

(and other search engines or directories)• From OAIster

(and OAI-compliant service providers)

What is needed?

• Rich metadata in IR– rich enough to be matched with publisher version

• Z39.88 (OpenURL) compliant?• Or publisher version’s DOI?

• How should the metadata be given to link-servers?– Preliminary harvesting into the knowledgebase?– Or on-the-fly transaction?

• Super repository needed for IRs? (like CrossRef)

Conclusion

• We, as a repository, need linking service to open access repositories for our researchers as authors

• And we, as a library, need linking service to open access repositories for our researchers as readers

• We’d like you to join us!
