## 2023-05-03

- Alliance's TIP team emailed me to ask about issues authenticating on CGSpace
  - It seems their password expired, which is annoying
- I continued looking at the CGSpace subjects for the FAO / AGROVOC exercise that I started last week
  - There are many of our subjects that would match if they added a "-" like "high yielding varieties" or used singular...
  - Also I found at least two spelling mistakes, for example "decison support systems", which would match if it was spelled correctly
- Work on cleaning, proofing, and uploading twenty-seven records for IFPRI to CGSpace

<!--more-->

- I notice there are a few dozen locks from the `dspaceWeb` pool that are five days old on CGSpace so I killed them

```console
$ psql < locks-age.sql | grep " days " | awk -F"|" '{print $10}' | sort -u | xargs kill
```

- Sync DSpace Test with CGSpace
- I replaced one item's thumbnail with a WebP version and XMLUI displays it fine
- I spent some time checking the CMYK issue with Arch's ImageMagick 7 and the Docker container and I think ImageMagick 7 just handles CMYK wrong...
  - libvips does it correctly automatically and looks closer to the PDF
- Meeting about CG Core types

- Write a script to find the `metadata_field_id` values associated with the non-AGROVOC subjects I am working on for Sara
  - This is useful because we want to know who to contact for a definition
  - The script was:

```bash
while read -r subject; do
    metadata_field_id=$(psql -h localhost -U postgres -d dspacetest -qtAX <<SQL
        SELECT DISTINCT(metadata_field_id) FROM metadatavalue WHERE LOWER(text_value)='$subject'
SQL
)
    metadata_field_id=$(echo $metadata_field_id | sed 's/[[:space:]]/||/g')

    echo "$subject,$metadata_field_id"
done < <(csvcut -c 1 ~/Downloads/2023-04-26\ CGIAR\ non-AGROVOC\ subjects.csv | sed 1d)
```

- I also realized that Bernard Bett didn't have any items on CGSpace tagged with his ORCID identifier, so I tagged 230!

## 2023-05-11

- CG Core meeting
- Finalize looking at the CGSpace non-AGROVOC subjects for FAO

## 2023-05-12

- Export the Alliance community to do some country/region fixes
  - I also sent Maria and Francesca the export because they want to add more regions and subregions
- Export the entire CGSpace to check for missing Initiative collection mappings
  - I also adding missing regions

- I finally cleaned up and published my latest evaluation of [JPEG, WebP, and AVIF](https://alanorth.github.io/improved-dspace-thumbnails/evaluating-jpeg-webp-avif.html)
  - I [filed an issue on DSpace](https://github.com/DSpace/DSpace/issues/8849) to track this

## 2023-05-17

- Re-sync CGSpace to DSpace 7 Test
- I came up with a naive patch to use WebP instead of JPEG in the DSpace ImageMagick filter, and it works, but doesn't replace existing JPEGs... hmmm
  - Also, it does PDF to WebP to WebP haha

## 2023-05-18

- I created a [pull request](https://github.com/DSpace/DSpace/pull/8850) to improve some minor documentation, typo, and logic issues in the DSpace ImageMagick thumbnail filters
- I realized that there is a quick win to the generation loss issue with ImageMagickThumbnailFilter
  - We can use ImageMagick's internal MIFF instead of JPEG when writing the intermediate image
  - According to the [libvips author PNG is very slow](https://github.com/libvips/libvips/issues/571)!
  - I re-ran my `generation-loss.sh` script using MIFF and found that it had essentially the same results as PNG, which is about 1.1 points higher on the ssimulacra2 (v2.1) scoring scale
  - Also, according to my tests with the cosmo rusage.com utility, I see that MIFF is indeed much faster than PNG
  - I updated my pull request to add this quick win
- Weekly CG Core types meeting
  - Low attendance so I just kept working on the spreadsheet
  - We are at the stage of voting on definitions
