In this meetup, the OpenRefine team demonstrated how it's already possible to edit structured data on existing Wikimedia Commons files, using a version 3.6 snapshot release of OpenRefine (it's not possible with the 3.5.x versions or earlier). An explanation of this process can be watched in the meetup's video recording.
The start of this process is also explained in this short video:
Monthly OpenRefine / Wikimedia office hours
In the upcoming months, the OpenRefine team will host monthly office hours for OpenRefine users from the Wikimedia community. You can meet and ask questions to other OpenRefine users here, and talk to members of the development team. These office hours are informal, have no set agenda, and are not recorded.
For now, we have scheduled office hours until end June 2022. Time of the day alternates to accommodate participants from diverse time zones. If these office hours prove to be popular, we will plan more of these later!
