UKM e-Journal System (OAI-PMH)

Open Journal Systems 2.4.8.1 platform self-hosted at ejournal.ukm.my (CNAME ejournals.ukm.my), carrying the journals published by UKM faculties, institutes and UKM Press. Its OAI-PMH 2.0 interface is live and unauthenticated: repositoryName "UKM e-Journal System", adminEmail nurhafizah@ukm.edu.my, repositoryIdentifier ojs.ukm.my, earliestDatestamp 2012-02-19, deletedRecord policy persistent, gzip and deflate compression advertised, five metadata formats (oai_dc, oai_marc, marcxml, nlm, rfc1807) and 100 sets. This surface was not in UKM's profile before 2026-09-01. It is the publishing counterpart of the university's Crossref membership — UKM Press mints 10.17576 DOIs against the articles it exposes. OJS 2.4.8.1 predates the PKP REST API, so OAI-PMH is the only machine-readable interface it offers; /api/v1/contexts returns 404.

  title: UKM e-Journal System — OAI-PMH 2.0
  version: '2.0'
  summary: OAI-PMH metadata harvesting interface for UKM's Open Journal Systems journal platform.
  description: >-
    Institution-operated OAI-PMH 2.0 harvesting interface for the UKM e-Journal System, an Open
    Journal Systems 2.4.8.1 installation self-hosted by Universiti Kebangsaan Malaysia on its own
    domain, ejournal.ukm.my (CNAME ejournals.ukm.my). Repository name "UKM e-Journal System",
    adminEmail nurhafizah@ukm.edu.my, repositoryIdentifier ojs.ukm.my, earliestDatestamp
    2012-02-19T15:55:15Z, deletedRecord policy "persistent", granularity to the second, gzip and
    deflate compression advertised. Five metadata formats are offered: oai_dc, oai_marc, marcxml,
    nlm, rfc1807. ListSets returns 100 sets — one per journal and journal section carried by the
    platform. No authentication.

    This surface was not in UKM's profile before 2026-09-01. It is the publishing counterpart of
    the university's Crossref membership: UKM Press (Crossref member 7332, prefix 10.17576) mints
    DOIs for the articles this endpoint exposes.

    OJS 2.4.8.1 predates the PKP REST API, which arrived in OJS 3.x — /api/v1/contexts returns 404
    on this deployment, so OAI-PMH is the only machine-readable interface it offers. This
    description was written by API Evangelist from live probes on 2026-09-01; UKM publishes no
    OpenAPI of its own.
