I dumped all the CGSpace DOIs and resolved them with my crossref_doi_lookup.py script
- Then I did some work to add missing abstracts (about 900!), volumes, issues, licenses, publishers, and types, etc

Spend some time looking at duplicate DOIs again…

Discuss RSS feeds and OpenSearch with IWMI
- It seems our OpenSearch feed settings are using the defaults, so I need to copy some of those over from our old DSpace 6 branch
I saw a patch for an interesting issue on DSpace GitHub: Error submitting or deleting items - URI too long when user is in a large number of groups
- I hadn’t realized it, but we have lots of those errors:

$ zstdgrep -a 'URI Too Long' log/dspace.log-2024-04-* | wc -l
1423

- I finally finished looking at the duplicate DOIs for journal articles
- I updated the list of handle redirects and there are 386 of them!

Spend some time working on the IFPRI 2020–2021 batch
- I started by checking for exact duplicates (1.0 similarity) using DOI, type, and issue date

I couldn’t figure out how to do a complex join on withdrawn items along with their metadata, so I pull out a few like titles, handles, and provenance separately:

dspace=# \COPY (SELECT i.uuid, m.text_value AS uri FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=25) TO /tmp/withdrawn-handles.csv CSV HEADER;
dspace=# \COPY (SELECT i.uuid, m.text_value AS title FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=64) TO /tmp/withdrawn-titles.csv CSV HEADER;
dspace=# \COPY (SELECT i.uuid, m.text_value AS submitted_by FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=28 AND m.text_value LIKE 'Submitted by%') TO /tmp/withdrawn-submitted-by.csv CSV HEADER;

Then joined them:

$ csvjoin -c uuid /tmp/withdrawn-title.csv /tmp/withdrawn-handles.csv /tmp/withdrawn-submitted-by.csv > /tmp/withdrawn.csv

This gives me an insight into who submitted at 334 of the duplicates over the past few years…
I fixed a few hundred titles with leading/trailing whitespace, newlines, and ligatures like ﬀ, ﬁ, ﬂ, ﬃ, and ﬄ
