+Note: running 2021-05-28 pacific time, but 2021-05-29 UTC.
+
+First downloaded bulk metadata from doaj.org and uploaded into archive.org item
+as a snapshot.
+
+## Journal Metadata Import
+
+Before doing article import, want to ensure journals all exist.
+
+Use chocula pipeline, and to be simple/conservative don't update any
+containers, just create if they don't already exist.
+
+Run the usual chocula source update, copy to data dir, update sources.toml,
+etc. Didn't bother with updating container counts or homepage status. Then
+export container schema:
+
+    python -m chocula export_fatcat | gzip > chocula_fatcat_export.2021-05-28.json.gz
+
+Upload to fatcat prod machine, unzip, and then import to prod:
+
+    export FATCAT_AUTH_WORKER_JOURNAL_METADATA=[...]
+    ./fatcat_import.py chocula /srv/fatcat/datasets/chocula_fatcat_export.2021-05-28.json
+    => Counter({'total': 175837, 'exists': 170358, 'insert': 5479, 'exists-by-issnl': 5232, 'skip': 0, 'update': 0})
+
+That is a healthy batch of new records!
+
+## Article Import
+
+Transform all the articles into a single JSON file:
+
+    cat doaj_article_data_*/article_batch*.json | jq .[] -c | pv -l | gzip > doaj_article_data_2021-05-25_all.json.gz
+    => 6.1M 0:18:45 [5.42k/s]
+
+    zcat doaj_article_data_2021-05-25_all.json.gz | shuf -n10000 > doaj_article_data_2021-05-25_sample_10k.json
+
+Also upload this `_all` file to archive.org item.
+
+Ready to import! Start with sample:
+
+    export FATCAT_AUTH_WORKER_DOAJ=...
+    zcat /srv/fatcat/tasks/202105_doaj/doaj_article_data_2021-05-25_sample_10k.json.gz | ./fatcat_import.py doaj-article --issn-map-file /srv/fatcat/datasets/ISSN-to-ISSN-L.txt -
+    => Counter({'total': 10000, 'exists': 8743, 'exists-fuzzy': 1044, 'insert': 197, 'skip': 14, 'skip-title': 14, 'skip-doaj-id-mismatch': 2, 'update': 0})
+
+Then the full import, in parallel, shuffled (because we shuffled last time):
+
+    zcat /srv/fatcat/tasks/202105_doaj/doaj_article_data_2021-05-25_all.json.gz | shuf | pv -l | parallel -j12 --round-robin --pipe ./fatcat_import.py doaj-article --issn-map-file /srv/fatcat/datasets/ISSN-to-ISSN-L.txt -
+    => Counter({'total': 512351, 'exists': 449996, 'exists-fuzzy': 50858, 'insert': 10826, 'skip': 551, 'skip-title': 551, 'skip-doaj-id-mismatch': 120, 'update': 0})
+    => extrapolating, about 129,912 new release entities. 2.1% insert rate
+
+NOTE: large number of warnings like:
+
+    UserWarning: unexpected DOAJ ext_id match after lookup failed doaj=5d2ebb760ad24ce68ec8079bc82c8d78 ident=dvtl2xpn4nespfrj6gad6mrk44
