Work on CGSpace duplicate DOIs more

2024-04-08

Start working on IFPRI’s 2022 batch import
- I ran the duplicate checker against CGSpace and started downloading all linked PDFs

2024-04-09

Continue working on IFPRI’s 2022 batch import
- I started validating the potential duplicates in OpenRefine

2024-04-12

Finish working on the 650 IFPRI 2022 records that were not already on CGSpace, then uploaded them
- I need to merge the metadata for the remaining 212 that are already on CGSpace
Spend some time looking at duplicate DOIs again…

Delete ~260 duplicate metadata values using the elaborate SQL and sort method I documented here: https://github.com/DSpace/DSpace/issues/8253#issuecomment-1331756418
Tony noticed that the DSpace 7 REST API is very slow with the embeds so I profiled a bit:

$ time curl -s -o /dev/null 'https://cgspace.cgiar.org/server/api/discover/search/objects?query=cg.identifier.project%3AIFPRI*&scope=8f1e9650-fe87-4e6e-889a-1cacfb747408&page=0&size=100&embed=thumbnail,bundles/bitstreams&sort=dcterms.issued,desc'
curl -s -o /dev/null   0.01s user 0.01s system 0% cpu 47.515 total
$ time curl -s -o /dev/null 'https://cgspace.cgiar.org/server/api/discover/search/objects?query=cg.identifier.project%3AIFPRI*&scope=8f1e9650-fe87-4e6e-889a-1cacfb747408&page=0&size=100&sort=dcterms.issued,desc' 
curl -s -o /dev/null   0.01s user 0.01s system 0% cpu 4.764 total

Finalize processing the remaining 206 items from the IFPRI 2022 batch set that already existed on CGSpace
- I merged metadata with the existing items
- There are still six remaining items that I identified as being duplicates (3x2) in the IFPRI set itself
