  Live probes 2026-08-19 of s-space.snu.ac.kr (DSpace Generator meta tag),
  kossda.snu.ac.kr (DSpace Generator meta tag), the eduGAIN metadata registration
  extension for https://kafegw.snu.ac.kr/idp/simplesamlphp, and negative probes for
  changelog / status / deprecation surfaces on snu.ac.kr.
versioning:
  scheme: protocol-version
  mechanism: >-
    None of SNU's surfaces are versioned by SNU. Each is pinned to the version of the
    protocol it implements — OAI-PMH 2.0, OpenSearch 1.1, SAML 2.0 — and the only version
    that moves is the version of the software underneath it, which SNU does not announce.
  docs: null
  notes: >-
    There is no API version header, no version path segment, and no published version
    policy on any SNU surface. A consumer's only version signal is the `<meta
    name="Generator">` tag the repository software emits.
software_versions:
  - surface: S-Space
    host: s-space.snu.ac.kr
    software: DSpace 5.5
    evidence: '<meta name="Generator" content="DSpace 5.5"/> in the served HTML, 2026-08-19'
    note: >-
      DSpace 5.5 was released in 2016 and is long out of support upstream; DSpace 7 and 8
      have shipped since. This matters to an integrator: the DSpace 7 REST API
      (/server/api) that most current DSpace tooling targets does not exist here, and the
      repository's only programmable surfaces are the 5.x-era OAI-PMH and OpenSearch ones.
  - surface: KOSSDA
    host: kossda.snu.ac.kr
    software: DSpace 5.6
    evidence: '<meta name="Generator" content="DSpace 5.6"/> in the served HTML, 2026-08-19'
  - surface: SNU Identity Provider
    host: kafegw.snu.ac.kr
    software: SimpleSAMLphp
    evidence: >-
      Endpoint paths /saml/module.php/saml/idp/* are the SimpleSAMLphp layout; exact
      release not disclosed.
deprecation:
  policy_url: null
  changelog: null
  sunset_header: false
  notes: >-
    SNU publishes no deprecation policy, no changelog, and no RFC 8594 Sunset or
    Deprecation headers on any surface. A consumer would learn of a breaking change by
    the harvest failing.
key_expiry:
  - surface: SNU Identity Provider
    what: SAML signing and encryption X.509 certificates
    not_after: '2028-06-03'
    issued: '2018-06-04'
    note: >-
      Ten-year self-signed certificates issued to CN=kafegw.snu.ac.kr. Recorded because
      it is the one hard dated commitment anywhere in SNU's public surface, and because a
      federation partner needs the rollover date.
  - surface: SNU Identity Provider registration
    what: KAFE federation registration
    registered: '2024-06-25'
sla:
  url: null
  public_uptime_target: null
  status_page: null
  notes: >-
    No status page was found on any snu.ac.kr host. KOSSDA's OAI-PMH Identify required a
    read timeout above 45 seconds to complete on 2026-08-19 and failed at 30s and 45s;
    there is no published availability commitment against which to read that.
