Metadata Interoperability for Institutional Repositories: A Case Study in Malang City Academic Libraries

The aim of this study is to understand, describe, and analyze metadata interoperability in Universitas Brawijaya Library that used Brawijaya Knowledge Garden (BKG) and Eprints software, University of Muhammadiyah Malang Library that used Ganesha Digital Library (GDL) and Eprints software, and Malang State Library that used Muatan Lokal (Mulok) software. This study also discussed supporting and inhibiting factors for interoperability metadata. This study employed a case study-qualitative approach. The finding indicates that the metadata interoperability can be performed by using metadata crosswalks. Implementation metadata crosswalks by mapping BKG fields and GDL Fields to the Dublin Core Metadata Element Set (DCMES). The results in the mapping of appropriate metadata schemes without removing the existing metadata scheme element and demonstrating technical specifications for standard metadata. Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) features can use for metadata interoperability in the union catalog that have been being developed by the National Library of Indonesia, called Indonesia OneSearch. The supporting factors in metadata interoperability are standard metadata and a standard protocol for interoperability; whereas, the inhibiting factor is the minimum human resources having metadata capability and the open access policy that has not applied to each academic libraries. All of those academic libraries need to make an effort to external interoperability to union catalogs to improve visibility digital content and applied open access policies.
