-# Fatcat Production Import CHANGELOG
-
-This file tracks major content (metadata) imports to the Fatcat production
-database (at https://fatcat.wiki). It complements the code CHANGELOG file.
-
-In general, changes that impact more than 50k entities will get logged here;
-this file should probably get merged into the guide at some point.
-
-This file should not turn in to a TODO list!

-## 2021-11
-
-Ran a series of cleanups. See background and prep notes in `notes/cleanups/`
-and specific final commands in this directory. Quick summary:
-
-- more than 9.5 million file entities had truncated timestamps wayback URLs,
- and were fixed with the full timestamps. there are still a small fraction
- (0.5%) which were identified but not corrected in this first pass
-- over 140k release entities with non-lowercase DOIs were updated with
- lowercase DOI. all DOIs in current release entities now lowercase (at least,
- no ASCII uppercase characters found)
-- over 220k file entities with incorrect release relation, due to an
- import-time code bug, were fixed. a couple hundred questionable cases remain,
- but are all mismatched due to DOI slash/double-slash issues and will not be
- fixed in an automated way.
-- de-uplicated a few thousand file entities, on the basis of SHA-1 hash
-- updated file metadata for around 160k file entities (a couple hundred
- thousand remain with partial metadata)

-## 2021-06
-
-Created new containers via chocula pipeline. Did not update any existing
-chocula entities.
-
-Ran DOAJ import manually, yielding almost 130k new release entities.
-
-Ran dblp import manually, resulting in about 17k new release entities, as well
-as 108 new containers. Note that 146k releases were not inserted due to
-`skip-dblp-container-missing` and 203k due to `exists-fuzzy`.
-
-## 2020-12
-
-Updated ORCIDs from 2020 dump. About 2.4 million new `creator` entities.
-
-Imported DOAJ article metadata from a 2020-11 dump. Crawled and imported
-several hundred thousand file entities matched by DOAJ identifier. Updated
-journal metadata using chocula took (before the release ingest). Filtered out
-fuzzy-matching papers before importing.
-
-Imported dblp from a 2020 snapshot, both containers (primarily for conferences
-lacking an ISSN) and release entities (primarily conference papers). Filtered
-out fuzzy-matching papers before importing.
-
-## 2020-03
-
-Started harvesting both Arxiv and Pubmed metadata daily and importing to
-fatcat. Did backfill imports for both sources.
-
-JALC DOI registry update from 2019 dump.
-
-## 2020-01
-
-Imported around 2,500 new containers (journals, by ISSN-L) from chocula
-analysis script.
-
-Imported DOIs from Datacite (around 16 million, plus or minus a couple
-million).
-
-Imported new release entities from 2020 Pubmed/MEDLINE baseline. This import
-included only new Pubmed works cataloged in 2019 (up until December or so).
-Only a few hundred thousand new release entities.
-
-Daily "ingest" (crawling) pipeline running.
-
-## 2019-12
-
-Started continuous harvesting Datacite DOI metadata; first date harvested was
-`2019-12-13`. No importer running yet.
-
-Imported about 3.3m new ORCID identifiers from 2019 bulk dump (after converting
-from XML to JSON): <https://archive.org/details/orcid-dump-2019>
-
-Inserted about 154k new arxiv release entities. Still no automatic daily
-harvesting.
-
-"Save Paper Now" importer running. This bot only *submits* editgroups for
-review, doesn't auto-accept them.
-
-## 2019-11
-
-Daily ingest of fulltext for OA releases now enabled. New file entities created
-and merged automatically.
-
-## 2019-10
-
-Inserted 1.45m new release entities from Crossref which had been missed during
-a previous gap in continuous metadata harvesting.
-
-Updated 304,308 file entities to remove broken
