It would be good if the duplicity list showed the best-match WD label (for my language :)) and allowed a one click article-item merge. Many of the arz hits at the moment are galaxies with very distinct names, and even if they have slightly different hyphenation it would be easy to match many from the list without going through them individually.

Thanks for this. I like all your criteria, although I think I want an even tighter limit on #3, and am hoping for a little more pizzaz. For me "web" is a bit bland in that every extension is interacting with the www.

The name was rejected because it's "best to avoid using "Wikidata" (or other project names) as the first word in the app title". Has anyone got any other suggestions?

Eek, scary. Yes, here you go https://github.com/99of9/Wikidata-Connect . Please be gentle, it's still very rough, and I'm totally new to this game!

Here's a video demo of my first version.

Here's my similar first-step idea. You are browsing the web, and find a page on any other site about an item that should have a Wikidata item. You click a bookmarklet, which instantly tells you in a side panel which identifier property should be linked, and if it is linked, which Wikidata item the ID is linked from.

This used to work.

I don’t really like property_threshold ... with the output of « 0 (0%) » there is no way of telling whether this is an actual zero

I agree - I cannot imagine a situation where I would need this.

Looks good, thanks.

I've made progress on this. The page already calls a template ("Coloured cell") per cell, so my concern about template limits is irrelevant. So I decided to go with your "option 2", and made a helper template to generate these links. It has been set up as a wrapper for Coloured cell.

Or if that is too much, scrap the counts entirely (a percentage is already clear), and add two links with the symbols + and -. So it could end up simply as "86.56% (+ -)"

In the brackets you already show the number of items with this property. Hyperlink that. The second link for the negatives could also be in the brackets as a count, so it might look like "86.56% (2300:357)" where both the 2300 and the 357 are hyperlinks.

Does wikidata have a limit on how many templates can be on a page?

Thanks
