  title: KURENAI Repository API (DSpace 7.6 + ) OAI-PMH REST API
  description: 'Machine-readable interfaces for the Kyoto University Research Information Repository (KURENAI), a DSpace 7.6 instance. Two confirmed-live surfaces are described: the DSpace REST API (HAL+JSON) rooted at /server/api, and the OAI-PMH 2.0 metadata harvesting endpoint at /server/oai/request. Only paths and shapes verified against the live system are included. Item-level REST endpoints require authentication; the public surfaces (root, communities, collections, OAI-PMH) are anonymous.'
