Any ideas as to what would be good practices for annotating images on #wikicommons using structured data?

cf. annotations such as these, but with #wikidata items and not wikipedia links: https://commons.wikimedia.org/wiki/File:Prequile_lyon_1863.jpg

maybe @abbe98 's Image annotator app? https://image-annotator.toolforge.org/

It doesn't appear to be working now, however.

@awinkler yeah, it died to WMFs tool purge a few years ago.

I built it for a former employer and WMF as a part of a SDC research project so I bet no one feels any ownership today.
