  title: edoc-Server DSpace REST API (Humboldt-Universität zu Berlin) Core Discovery API
  description: Public, read-oriented subset of the DSpace REST API powering the edoc-Server Open Access institutional repository of Humboldt-Universität zu Berlin. The repository runs DSpace 8 and exposes communities, collections, items, and a discovery search as HAL/JSON resources. This description was authored from the live API responses observed at the base URL; only publicly reachable, unauthenticated read endpoints are documented here. Write, submission, workflow, and authenticated endpoints exist in DSpace but are intentionally omitted because they require authentication and are not publicly self-service.
