## 2024-05-01

- 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

- 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](https://github.com/DSpace/DSpace/issues/9544)
  - I hadn't realized it, but we have lots of those errors:

```console
$ 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!

## 2024-05-09

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- I couldn't figure out how to do a complex join on withdrawn items along with their metadata, so I pull out a few like titles, handles, and provenance separately:

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\COPY (SELECT i.uuid, m.text_value AS uri FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=25) TO /tmp/withdrawn-handles.csv CSV HEADER;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\COPY (SELECT i.uuid, m.text_value AS title FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=64) TO /tmp/withdrawn-titles.csv CSV HEADER;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(SELECT i.uuid, m.text_value AS submitted_by FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=28 AND m.text_value LIKE 'Submitted by%') TO /tmp/withdrawn-submitted-by.csv CSV HEADER;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

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$ csvjoin -c uuid /tmp/withdrawn-title.csv /tmp/withdrawn-handles.csv /tmp/withdrawn-submitted-by.csv 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 /tmp/withdrawn.csv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