This article discusses the Prometheus Unarchiver project, which is part of a project to promote the use of TUFS’s institutional repository by providing metadata for the language resources housed therewithin to the OLAC repository. It outlines how the institutional repository as a data provider transmits metadata through the Prometheus Unarchiver website, acting as a harvester, to the OLAC repository as a service provider, while addressing specific requirements and challenges encountered during implementation. First, it examines the transition from Prometheus Unarchiver to the OLAC repository based on the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) and OLAC Metadata. Second, it details the retrieval of metadata from the institutional repository in the Japan Consortium for Open Access Repository (JPCOAR) Schema format and its conversion to the OLAC metadata format. Third, it describes the implementation steps of the Prometheus Unarchiver project, including acquiring metadata in the JPCOAR format via OAI-PMH, transforming it into OLAC repository-compliant static XML data, and providing these data to the OLAC repository’s crawling robots. Additionally, it contrasts the OLAC repository’s open archive context with the Linguistic Linked Open Data cloud’s open data framework, indicating that while the two contexts may not be currently connected, registering research data in institutional repositories could create such a linkage through the Institutional Repositories DataBase. This article emphasizes the growing importance of metadata intermediaries, such as Prometheus Unarchiver, in enhancing research data discoverability and facilitating their use.
