- Bosede from IITA said we can use "SOCIAL SCIENCE & AGRIBUSINESS" in their new IITA theme field to be consistent with other places they are using it
- Run all system updates on DSpace Test (linode19) and reboot it
## 2019-02-12
- I notice that [DSpace 6 has included a new JAR-based PDF thumbnailer based on PDFBox](https://jira.duraspace.org/browse/DS-3052), I wonder how good its thumbnails are and how it handles CMYK PDFs
- On a similar note, I wonder if we could use the performance-focused [libvps](https://libvips.github.io/libvips/) and the third-party [jlibvips Java library](https://github.com/codecitizen/jlibvips/) in DSpace
- Testing the `vipsthumbnail` command line tool with [this CGSpace item that uses CMYK](https://cgspace.cgiar.org/handle/10568/51999):
```
$ vipsthumbnail alc_contrastes_desafios.pdf -s 300 -o '%s.jpg[Q=92,optimize_coding,strip]'
```
- (DSpace 5 appears to use JPEG 92 quality so I do the same)
