--- title: "May, 2024" date: 2024-05-01T10:39:00+03:00 author: "Alan Orth" categories: ["Notes"] --- ## 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 ## 2024-05-05 - Spend some time looking at duplicate DOIs again... ## 2024-05-06 - Spend some time looking at duplicate DOIs again... ## 2024-05-07 - 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... ## 2024-05-08 - 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(1.0 similarity) using DOI, type, and issue date ## 2024-05-12 - I couldn't figure out how to do a complex join on withdrawn items along with their metadata, so I pull out a few like titles, handles, and provenance separately: ```psql dspace=# \COPY (SELECT i.uuid, m.text_value AS uri FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=25) TO /tmp/withdrawn-handles.csv CSV HEADER; dspace=# \COPY (SELECT i.uuid, m.text_value AS title FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=64) TO /tmp/withdrawn-titles.csv CSV HEADER; dspace=# \COPY (SELECT i.uuid, m.text_value AS submitted_by FROM item i JOIN metadatavalue m ON i.uuid = m.dspace_object_id WHERE withdrawn AND m.metadata_field_id=28 AND m.text_value LIKE 'Submitted by%') TO /tmp/withdrawn-submitted-by.csv CSV HEADER; ``` - Then joined them: ```console $ csvjoin -c uuid /tmp/withdrawn-title.csv /tmp/withdrawn-handles.csv /tmp/withdrawn-submitted-by.csv 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 /tmp/withdrawn.csv ``` - This gives me an insight into who submitted at 334 of the duplicates over the past few years...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
