Here is a thread to get an overview of who will be attending FOSDEM 2024.
So far I am aware of @Ainali attending and I will also be there. I will give a lightning presentation of the reproducibility project in the Open Research devroom. It is also likely that some staff members from Code for Science & Society and Wikimedia Deutschland will attend.
It seems that Svante Schubert (the maintainer of the odftoolkit library we use to parse LibreOffice files in OpenRefine) will also attend and I will try to use this opportunity to get a better sense of the state of this library.
I'd be happy to identify more people to talk to, whatever their relation to OpenRefine may be.
