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!
