I finally made the batch upload I was planning for a while. I’m the kind of person who likes to try out a new technology first and then figure out the problems… (I think I should have made this test batch smaller). My data had some issues–I ended up removing all of the external links that I added as official websites. You can see some of the uploads on my Wikidata contributions page.
My batch had about 2400 reconciled items. We had matched 711 through mix’n’match; I used the property for the MLCAD as a proxy for mix’n’match reconciliation… I think? I also tried to reconcile using birthdates as a way to match items. That means that some 1300 items were ones that I matched using the reconciliation tool in OpenRefine. Some of these, at least several hundred, were incorrect. Other Wikidata users reverted some of my batch edits because they were reconciled to the wrong person. I would like to update my data with their reversions. Is there a way to download which items were reverted and un-reconcile them in my openrefine file?
