• Author andReader perspective
• Linkauthorsandcontributorswiththeirresearchoutputandeasenamedisambiguation
• Service provider perspective
• Avoidoverloadingofoai_dcmetadata
• Makemaintenanceandmappingsofcontrolledvocabularieseasierbyhelpofidentifiers
• Makeidentificationofresourceseasier(e.g.forTDM)
• Improvealignmentwithotherregionalrepositorynetworks
• Agree on a shared set of metadata properties and controlled vocabularies
• Allow for region specific extensions
• Examples: LA Referencia, JAIRO (Japanese Institutional Repositories Online)
Upgrade needs from different perspectives

12. Application Profile
Overview

13. • Build an application profile based on established and widely
used metadata schemes in repositories
• DublinCoreandDataCitev4.1
• Allow for additional properties when needed
• Align with other repository networks
Approach

14. • Re-use and adaptation of controlled values used in the
DataCite schema
• E.g.identifiertypes,roletypes,relationtypes
• Controlled Vocabularies defined by the COAR community
• E.g.resourcetypes,accessrights,versiontypes
• Controlled Vocabularies defined in OpenMinTeD Guidelines
• E.g.licenses
Controlled Vocabularies

19. THE CHALLENGE
•Enrichment is straightforward
•Harvesting from repository and return to repository its records if they
have been “enriched” by deduplication and/or inference
•Addition is less obvious
•Based on relationships, in turn identified by inference algorithms
•Must be augmented with notion of “trust” to enable “tuning” options in
order to reduce false positive notifications
