Since 2019, it is possible to add structured data to files on Wikimedia Commons  (SDC = Structured Data on Commons). But there are no very advanced and user-friendly tools yet to edit the structured data of very large and very diverse batches of files on Commons. And there is no batch upload tool yet that supports SDC.
The OpenRefine  community wants to fill this gap: in the upcoming year, we would like to build brand new features in the open source OpenRefine tool, allowing batch editing and batch uploading SDC :-) As these are major new functionalities in OpenRefine, we have applied for a Project Grant . Your feedback  and (if you support this plan) endorsements are very welcome.
Thanks in advance, and many greetings,
Sandra (User:Spinster / User:SFauconnier) as member of the OpenRefine steering committee
Antonin (User:Pintoch) as OpenRefine developer
