Getty's Ex Libris Primo gateway caps any single query at offset<=1999 and
limit<=1000, so GettyHarvester -- which pages by offset -- retrieves ~2,000 of
~101,400 records and reports SUCCESS. That silent 98% shortfall reached
production in February 2026, and it is why the hub has been on hold since its
last good harvest in February 2021.
A single record IS retrievable by id, with no offset involved:
q=rid,exact,GETTY_ROSETTAIE10176553 -> exactly 1 record
GettyRefreshHarvester looks up every known record id directly, then asks Getty's
own `newrecords` facet for anything added in the last 90 days. Validated against
the live endpoint: 101,384 of 101,393 records (99.99%), mapping 101,384
attempted / 101,384 successful / 0 failed.
The seed is `getty.harvest.seed`, the previous harvest's OriginalRecord.avro, so
each run's output becomes the next run's seed and discovered ids carry forward
automatically rather than by hand.
Hardening, because this runs ~101K requests against a partner's production
system:
- Aborts after 3 consecutive 403s rather than working through the whole seed
against an endpoint that has already refused us.
- Probes the route on the first lookup and fails immediately if the
allowlisted egress is not applied.
- Refuses to publish if under half the seeded ids resolve, so a collapsed
harvest cannot quietly replace a good one.
- Serialises Avro writes; the inherited writer is not thread-safe.
- Paces after the response body is read and the connection is closed. Sleeping
inside the urlopen context holds an idle connection open and the server drops
it, which looks like rate limiting and gets "fixed" by raising the delay --
making it strictly worse.
GettyHarvester is retained but no longer wired up. It becomes the correct
implementation again the moment Ex Libris lifts the offset cap, which is the
outcome we are pressing Getty for.
This method is temporary and does not guarantee completeness, which the docs and
scaladoc state plainly: `newrecords` tops out at 90 days, so a quarterly schedule
has no margin; and the GETTY_OCP side (78,613 of 101,393 records) carries no
usable facets -- measured 2026-09-12, it collapses to one rtype value and one
local2 value -- so it cannot be enumerated and its coverage rests entirely on the
seed. That has held only because OCP has not gained a record since 2021.

…ndow Getty's `newrecords` facet reaches back only 90 days, so an interval longer than that opens a permanent blind spot: records added after the last harvest but before the window opens are in neither the seed nor the discovery results, and no later run will find them either. GettyRefreshHarvester now reads the previous harvest's date out of the seed's activity path and logs a banner warning naming the exact date range that was lost. It warns rather than fails -- a late harvest is still much better than none, and refusing to run would widen the gap. Paired with moving Getty to a bi-monthly schedule (in ingestion3-conf), which leaves about a month of margin instead of sitting on the 90-day edge.

Update — the 90-day window is now mitigated on both sides. Two changes since the PR was opened, in 1. Getty moves to bi-monthly, not quarterly ( 2. The harvester warns when the interval exceeds the window anyway. It names the exact date range that was lost, so the operator knows what is unrecoverable rather than just that something is wrong. It warns rather than fails on purpose: a late harvest is still far better than none, and refusing to run would widen the very gap being reported. 10 more tests (33 in this suite, 1,271 total, all passing), including the edge case that 90 days exactly should stay quiet — crying wolf on a schedule that is working would train people to ignore it — and that a text-file seed carrying no date says nothing rather than guessing.

getty.harvest.seed named a specific harvest directory, which would have meant editing i3.conf after every ingest. That is run state, not configuration, and it is state the code can derive: OutputHelper writes activity directories as YYYYMMDD_HHMMSS-<hub>-<schema>, so the previous harvest is discoverable and the timestamp sorts lexically. GettyRefreshHarvester now lists the hub's harvest activity directory and takes the newest completed run. Directories without _SUCCESS are skipped, so a crashed Spark write cannot become the seed and silently shrink the next harvest. The output root is a run parameter (--output), not configuration, so it reaches the harvester through a new SeedsFromPreviousHarvest mixin that HarvestExecutor populates. Harvesters that do not mix it in are unaffected. getty.harvest.seed stays in the schema as an override for backfills and re-seeding, but is no longer set, so routine ingests need no config change.

A bootstrap id list belongs somewhere durable, not on whichever box happens to run the harvest. Source.fromFile cannot read an S3 URI; going through the same FileSystem API already used for directory listing makes a local path and an s3a:// URI behave identically.

The Slack notification echoed i3.conf's raw email value, so every name after the first ran straight into the previous address: Partner email sent to Sela Constan-Wahl<a@getty.edu>,Alyssa Loera<b@getty.edu> format_recipients normalises the separator to ", " for display. It collapses existing spacing first, so a list already written with spaces is not double-spaced. Display only. get_hub_email keeps returning the raw configured value, because send-ingest-email.sh passes that straight to the mail command -- the formatting is for humans reading Slack, not for the sender. Not Getty-specific; affects every hub's completion notification. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Getty lists every thumbnail twice in delivery.link. Measured across the 2026-09-12 harvest: all 101,384 records carry exactly two entries labelled "thumbnail", and in every one the two linkURLs are identical -- distinct count after dedup is 1 for 101,384 of 101,384 records. The entries differ only in their blank-node @id and a couple of empty attributes, so there is no preferred copy to choose between. It is a duplicate, not a choice. The effect was a "More than one value mapped, one expected, preview" warning on 100% of Getty records -- 101,384 warnings, 21% of everything the hub emits -- while Mapper.validatePreview silently kept whichever happened to come first. Harmless while the two values are identical, but it meant the selection was positional and nobody could see past the noise to the warnings that matter. The existing test asserted the duplicate as expected output; it now pins the dedup instead, and checks the fixture still contains both source entries so the test cannot quietly stop covering the case. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Getty had no edmRights mapping at all -- GettyMapping never defined the method, so it inherited the base trait's empty default and every record reached DPLA with edmRights unset. Across the 2026-09-12 harvest exactly two of 101,384 records publish a standardized rights URI (http://rightsstatements.org/vocab/InC/1.0/, in lds27). Those were reaching DPLA as free-text rights: a URI sitting in a text field, where it cannot function as a rights statement. This promotes it. A scan of every field of every record confirms Getty has no separate rights-URI field, so alongside the free text is the only place one can appear. (The only other pattern hits were "PDM" inside an inscription description -- "woven monogram in lower guard, right [partially legible in photograph]: PDM" -- which is why the match is against the whole value, not a substring.) Deliberately NOT a crosswalk. Getty's local statements -- the Open Content Program wording alone covers 77.5% of the hub -- stay in free-text rights untouched. What those statements mean is Getty's to declare, and assigning a URI to them here would change what the record says. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
All three are the same failure mode this harvester exists to prevent: finishing with fewer records than the source has, and reporting success. 1. Worker exceptions were discarded. ExecutorService.submit parks a task's exception in the Future it returns; dropping that meant a worker could die mid-record -- saveOutRecords on a full disk, an interrupt in the pacing sleep -- and take the id it was holding with it. The remaining workers drained the queue, so the run still "succeeded", just short. The futures are now retained and get() re-raises after the latch. 2. An indeterminate lookup could publish. After retries are exhausted, LookupFailed wrote no record, so the id would be absent from the next harvest's seed and never asked about again -- a transient error turning into permanent, invisible loss. Only Gone establishes absence; any LookupFailed now aborts before publishing. Re-running costs hours, losing records nobody notices costs more. 3. Discovery paging stepped past the ceiling. Offsets advanced 0 -> 1000 -> 2000, and 2000 > MaxOffset ended the loop without ever requesting 1999, skipping records 2000-2998 whenever a page came back full. Now 0 -> 1000 -> 1999, with seenHere suppressing the overlap, and a full page at the ceiling raises rather than returning a truncated set that looks whole. Also documents the accepted harvest.seed formats: a harvest directory, or a newline-delimited id file ending .txt/.ids. The extension is the only signal, so a .csv would have gone to the Avro reader and failed obscurely. Raised by CodeRabbit on #778. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

LocalHarvester.close() flushes and closes the inherited Avro writer, and nothing else does: HarvestExecutor calls cleanUp() on both success and failure, and cleanUp() only deletes the temp directory. harvest closed on three paths and leaked on five: an empty seed, a refused route probe, a worker exception re-raised from futures.get(), the discovery offset ceiling, and the resolved-fraction floor. Each left the writer holding a file cleanUp() was about to remove. Wrapped in try/finally. close() cannot simply be called twice -- it flushes first, and flushing a closed writer throws -- so it now goes through an idempotent guard, and the explicit calls at the throw sites are gone since the finally covers them. The normal close still happens before spark.read, per the issue #760 ordering. Raised by CodeRabbit on #778. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Both runbooks said getty.harvest.seed was "for backfills only", which is wrong in the case that actually bites: on a box with no completed Getty harvest there is nothing to auto-discover and the harvest aborts. The first production run hit exactly this and needed a bootstrap seed, which the docs did not mention. Now stated in both: the override wins when set, otherwise the newest harvest directory carrying _SUCCESS is used; a first run without one must be given a seed explicitly; an explicit seed is either a harvest activity directory or a newline-delimited id file ending .txt or .ids, since the extension is the only signal; and the override is removed once a harvest completes so carry-forward resumes.

The test defined its own copy of the next-offset formula and asserted against that, so it verified the test's arithmetic rather than the harvester's. Changing the production line would have left it green -- a test that could not fail. Extracted the step as a package-visible nextOffset and pointed both at it.

Harvest-side follow-up:
|
This branch has not been deployed
1 participant
Getty has been on hold since its last good harvest in February 2021. This gets it running again: 101,384 of 101,393 records (99.99%), mapping 101,384 attempted / 101,384 successful / 0 failed, validated against the live endpoint.
The problem
Getty's Ex Libris Primo gateway caps any single query at
offset <= 1999andlimit <= 1000.GettyHarvesterpages by offset, so it retrieves ~2,000 of ~101,400 records — and reports success. That silent 98% shortfall reached production in February 2026.It is not rate limiting. No retry, backoff, or page-size change moves it.
The approach
A single record is retrievable by id, with no offset involved:
GettyRefreshHarvesterlooks up every known record id directly, then asks Getty's ownnewrecordsfacet for anything added in the last 90 days.The seed is
getty.harvest.seed— the previous harvest'sOriginalRecord.avro. Each run's output becomes the next run's seed, so discovered ids carry forward automatically instead of by hand.Hardening
This makes ~101K requests against a partner's production system, so:
LocalHarvesteris not thread-safe.23 new unit tests (1,261 total, all passing). Everything load-bearing — URL construction, id extraction, the route-loss signal, seed parsing — lives in the companion object so it tests without Spark or a network.
This is temporary, and it does not guarantee completeness
Stated plainly in the scaladoc,
SCRIPTS.md,README_INGESTS.md, i3.conf and Confluence:newrecordsoffers only 07/30/90 days back, cumulative; 90 is the longestGETTY_OCPcannot be enumeratedrtypevalue and onelocal2value. Nothing to partition on.It keeps the aggregation from drifting. It is not a guarantee that DPLA holds every record Getty publishes. The real fix is Ex Libris lifting the cap or Getty providing a bulk feed — which is worth continuing to press for.
GettyHarvesteris retained but no longer wired up. It becomes correct again the moment the cap is lifted;GettyProfilejust needs re-pointing.Also here
getty.harvest.seedadded to the conf schema.PrimoVEHarvester.scala:74: it extracts ids as(doc \\ "control" \ "recordid").toString, which yields the json4s AST'stoStringrather than the id (there is already aFIXMEon the line). Harmless while ids are only written out, but it would corrupt exactly the seed round-trip this design depends on — so the new harvester extracts cleanly and a test pins it. This also affects MWDL and Mississippi and is worth a separate look.Before first run
getty.harvest.seedpoints ats3://dpla-master-dataset/getty/harvest/20260912_213156-getty-OriginalRecord.avro, which currently exists only on the ingest EC2 — it has not been synced to S3.
