edoc-Server DSpace REST API

Public, unauthenticated read API of the edoc-Server, the Open Access institutional repository of Humboldt-Universität zu Berlin, operated by the University Library's Arbeitsgruppe Elektronisches Publizieren. Live probe 2026-09-01 returned dspaceName "edoc-Server", dspaceVersion "DSpace 8.5-SNAPSHOT"; /core/communities and /discover/search/objects both answered 200, /core/items answered 401. The repository software is DSpace (open source, BSD, self-hosted) — the software is a third party's, the host, the deployment and the content are HU's, which is why this is `institution` and not `tenant`. HU publishes no OpenAPI for it; the three contracts below were authored by API Evangelist from live responses and each says so in its own description. They are three tag-split views of ONE surface, not three APIs — the June 2026 profile listed them as three separate entries and that inflation has been corrected here.

  title: edoc-Server DSpace REST API (Humboldt-Universität zu Berlin) Core 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.
