    Machine-readable description of the publicly accessible, read-only surface of
    the Repositorio Institucional Universidad Nacional de Colombia, powered by
    DSpace 7.6.5. Two interfaces are documented: the DSpace REST API (HAL+JSON)
    and the OAI-PMH 2.0 metadata harvesting interface. Only endpoints confirmed
    to resolve anonymously during discovery are included. Endpoints that require
    authentication (e.g. /server/api/core/items) are intentionally omitted.
