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.

@librerli yes, thanks, this tools does what I was looking for. UX is not entirely intuitive yet (especially in contexts of editathons with a non-specialist public)
@awinkler for the editathon purpose look at ISA tool: https://commons.wikimedia.org/wiki/Commons:ISA_Tool

@librerli that's 'just' structured data, right? No regions, if I understand correctly.

For structured data this looks very interesting.

@awinkler exactly. ISA tool is "just" for adding the depicts statement (P180) to a file.
but if added a depicts statement to a file, it is just one step behind to add the region with the Structured Region tool afterwards.
@librerli I'm wondering if @aboutgeo 's Annotation tools could be combined with the wikicommons annotation backend?
@awinkler @librerli I'd love to hear & learn more about it. In theory, annotorious.dev is embeddable into pretty much anything. But the way JS bundling works for Wikimedia/MediaWiki works is a bit of a mystery to me.
@aboutgeo @librerli maybe @LucasWerkmeister and @abbe98 can help, I don't know enough about these things. What is needed (imho): 1) Load image from Commons, 2) select region (rectangular or polygon), 3) provide suggestions for Wikidata items in input box, 4) write selected WD-Item either as P180 or P9664 + region as P2677 (rectang) or P8276 (polygon) Qualifier to Wikicommons.

@aboutgeo @librerli @LucasWerkmeister @abbe98 My usecase: Annotation of historic city map (https://commons.wikimedia.org/wiki/File:Selter_Berlin_1809.jpg). A tool with sleek ux would be great for editathons, object documentation in GLAMs and, why not, research. Storing info directly in Wikicommons would be very cool and FAIR (2/2)

@awinkler @aboutgeo if I would make another annotation tool I would probably use Annotorious + Wikimedias new client side auth rather than bother with userscripts/gadgets.
