|

- Skype with Michael and Peter, discussing moving the CGIAR Library to CGSpace
|
||||
- CGIAR people possibly open to moving content, redirecting library.cgiar.org to CGSpace and letting CGSpace resolve their handles
|
||||
- They might come in at the top level in one "CGIAR System" community, or with several communities
|
||||
- I need to spend a bit of time looking at the multiple handle support in DSpace and see if new content can be minted in both handles, or just one?
|
||||
- Need to send Peter and Michael some notes about this in a few days
|
||||
- Also, need to consider talking to Atmire about hiring them to bring ORCiD metadata to REST / OAI
|
||||
- Filed an issue on DSpace issue tracker for the `filter-media` bug that causes it to process JPGs even when limiting to the PDF thumbnail plugin: [DS-3516](https://jira.duraspace.org/browse/DS-3516)
|
||||
- Discovered that the ImageMagic `filter-media` plugin creates JPG thumbnails with the CMYK colorspace when the source PDF is using CMYK
|
||||
- Interestingly, it seems DSpace 4.x's thumbnails were sRGB, but forcing regeneration using DSpace 5.x's ImageMagick plugin creates CMYK JPGs if the source PDF was CMYK (see [10568/51999](https://cgspace.cgiar.org/handle/10568/51999)):
