description: >-
  Versioning, stability and retirement posture for the Umo IQ Public Feed, taken from the
  provider's own documentation and from what the live host does today. The headline finding is
  that this is a long-lived legacy surface: the host name itself ("retro") and the licence's
  unilateral termination clause are the provider's own framing of it.
versioning:
  in_contract: false
  scheme: document-revision
  current: '1.24'
  current_dated: '2021-05-18'
  detail: >-
    No version appears in the URL, query string or headers. Only the documentation is versioned.
    Revision 1.24 (18 May 2021) is the newest and moved the host from webservices.nextbus.com to
    retro.umoiq.com; the document's own revision history runs back to 1.0 (2 November 2009).
stability_policy:
  published: true
  url: https://retro.umoiq.com/xmlFeedDocs/NextBusXMLFeed.pdf
  statement: >-
    "It is intended that the commands and the resulting XML data change as little as possible in
    the future. There will be situations though when the feed will need to change. In particular,
    additional XML elements and properties might be added. This should not affect a proper XML
    client though because any new elements should simply be ignored."
  contract: additive-only; clients must ignore unknown elements
deprecation_policy:
  published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  detail: >-
    No deprecation policy, no notice period, no Sunset or Deprecation headers. The licence
    reserves the opposite: "Umo IQ reserves the right to terminate or limit the Feed to any or
    all users at any time and for any reason." An integrator has no contractual warning window.
  evidence_of_silent_change: >-
    The documentation's worked example agency, sf-muni, now returns 'Agency parameter "a=sf-muni"
    is not valid.' (probed 2026-09-19). Agencies leave the feed without any deprecation signal,
    and the published examples were not updated when they did.
sla:
  published: false
  detail: >-
    None. The licence disclaims all warranties, caps liability at the greater of one dollar and
    fees paid, and states "No support is to be provided by Umo IQ to external use of the Feed
    except for those under written contracts."
status_page:
  published: false
  url: null
  detail: >-
    No status page was found for the Umo IQ Public Feed. Searched the feed host, umoiq.com,
    umomobility.com and www.cubic.com on 2026-09-19; nothing public. No StatusPage pointer is
    wired in apis.yml as a result.
support:
  channel: email
  contact: umoiq.support@cubic.com
  detail: The feed documentation directs comments and suggestions to umoiq.support@cubic.com.
  announcements: >-
    Revision 1.11 of the documentation (2011) references e-mail groups for announcements and
    discussions; no current public list or archive was located in 2026.
