|
||
|
||
- 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
|

```

- Spend some time looking at duplicate DOIs again...
|
||
- 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
|
||
|
||
## 2024-05-12
|
||
|
||
- I couldn't figure out how to do a complex join on withdrawn items along with their metadata, so I pull out a few like titles, handles, and provenance separately: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\COPY (SELECT i.uuid, m.text_value AS uri FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=25) TO /tmp/withdrawn-handles.csv CSV HEADER;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\COPY (SELECT i.uuid, m.text_value AS title FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=64) TO /tmp/withdrawn-titles.csv CSV HEADER;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(SELECT i.uuid, m.text_value AS submitted_by FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=28 AND m.text_value LIKE 'Submitted by%') TO /tmp/withdrawn-submitted-by.csv CSV HEADER;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$ csvjoin -c uuid /tmp/withdrawn-title.csv /tmp/withdrawn-handles.csv /tmp/withdrawn-submitted-by.csv 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 /tmp/withdrawn.csv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
|
||
|
||

|
||
|
||
- Export a list of IFPRI information products with handle links and CONTENTdm links:
|
||
|
||
```
|
||
$ csvgrep -c 'dc.description.provenance[en_US]' -m 'CONTENTdm' cgspace.csv \
|
||
| csvcut -c 'id,dc.description.provenance[en_US],dc.identifier.uri[en_US]' \
|
||
| tee /tmp/ifpri-redirects.csv \
|
||
| csvstat --count
|
||
2645
|
||
```
|
||
|
||
- I discovered the `/server/api/pid/find` endpoint today, which is much more direct and manageable than the `/server/api/discover/search/objects?query=` endpoint when trying to get metadata for a Handle (item, collection, or community)
|
||
- The "pid" stands for permanent identifiers apparently, and we can use it like this:
|
||
|
||
```
|
||
https://dspace7test.ilri.org/server/api/pid/find?id=10568/118424
|
||
```
