    - term: Institutional Repository of Peking University (北京大学机构知识库)
      definition: >-
        The university's own scholarly record, at ir.pku.edu.cn, run by the PKU Library
        (pkuir@lib.pku.edu.cn) with content back to 2015-09-25. Organised into communities
        that mirror the university — 理学部, 人文学部, 专利 (patents, 25,721 items) — and
        exposed through an unauthenticated REST API, an OAI-PMH 2.0 endpoint and an
        OpenSearch Atom feed.

    - term: Handle prefix 20.500.11897
      definition: >-
        The Handle.Net prefix the repository owns and resolves. Every community,
        collection and item carries a handle under it, and /rest/handle/{prefix}/{suffix}
        resolves one to its object.
