## Formatting a math formula property

Density, density (Q29539)
enwiki shows L^{-3}M N
Expected ${\displaystyle L^{-3}M}$

{{Infobox physical quantity}} reads ISQ dimension (P4020). That is a [itex] formatted text. However, in enwiki it shows unformatted (see infobox demo).

I tried this: | data5 = [itex]{{#property:P4020}}[/itex] → error.

Note: the symbols like L and M should be upright, not italics. Issue raised at d:Property talk:P4020. Does not alter this problem.

Any suggestions? - DePiep (talk) 10:09, 11 January 2018 (UTC)

@DePiep: {{#invoke:wd|property|Q29539|P4020}} seems to work: ${\displaystyle L^{-3}M}$. Thanks. Mike Peel (talk) 11:23, 11 January 2018 (UTC)

Done Applied and works fine. Thx. -DePiep (talk) 11:42, 11 January 2018 (UTC)

Hello, occasionally (not always, confusingly) when I delete an article on Wikipedia, I get a notification that I have made an edit to Wikidata. I am quite sure I haven't, but when I went to look on Wikidata, sure enough, I apparently have made 11 edits there ([1]). I definitely have not made these edits. Can someone explain to me in simple terms a) What those edits are, and b) how I can stop them happening without my consent? Thanks fish&karate 14:56, 18 January 2018 (UTC)

It is removing the sitelink to enwiki when you delete the article. It'll only happen when the article has a Wikidata item linked, so very new articles or CSD candidates usually won't. -- ferret (talk) 15:00, 18 January 2018 (UTC)
Yes, but why are they showing up as my edits? I'm not making them. fish&karate 15:04, 18 January 2018 (UTC)
You are making them by deleting the article here. You shouldn't normally get notifications apart from on milestones - presumably you got saying that you'd made 10 edits on Wikidata? If so, the next one you should get is 100 edits. Thanks. Mike Peel (talk) 15:16, 18 January 2018 (UTC)
Thanks Mike, that makes sense. That being said I don't really want to edit Wikidata without consenting to do so, I assume I don't have a say in the matter? fish&karate 12:24, 19 January 2018 (UTC)
I am afraid the only option is to get blocked on Wikidata (or otherwise to stop moving and deleting pages completely).--Ymblanter (talk) 12:29, 19 January 2018 (UTC)
These sitelinks maintain the interwiki language links. It's mildly important that they get updated when you move or delete pages. -- ferret (talk) 12:38, 19 January 2018 (UTC)
I think the point is that Fish and karate didn't actually go to Wikidata and remove the sitelinks; the software did that for them. That must be unexpected for anyone who's not aware of the interconnectedness of everything, as Dirk Gently would put it. On the other hand, Fish and karate, you must accept that someone deleted those sitelinks on Wikidata, and if it wasn't you, who was it? --RexxS (talk) 14:05, 19 January 2018 (UTC)
That's what freaks me out man fish&karate 14:44, 19 January 2018 (UTC)
It is no different to what happens if you rename (move) or delete an image or other file on Commons - your action would show up in the edit history of any article that was transcluding that image, here and on any other Wikipedia or sister project. This has been the case for well over a decade. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 23:32, 20 January 2018 (UTC)
This is not correct. If I delete a file on Commons, it gets deleted by a bot here. It used to be like this but changed four or five years ago.--Ymblanter (talk) 00:57, 21 January 2018 (UTC)
"Delete" duly struck; thank you - but my general point stands. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:29, 21 January 2018 (UTC)

## Merge talk pages?

We seem to have both this page, and Wikipedia talk:Wikidata/2018 State of affairs (and, for that matter, Wikipedia talk:Wikidata/2017 State of affairs) that seem to be unnecessarily splitting discussions about wikidata - discussions on the state of affairs pages are going far beyond just discussing the topic of those pages. Why not have them all on this page instead? Thanks. Mike Peel (talk) 16:30, 7 February 2018 (UTC)
