Disallow Wikidata URLs

Is there a meaningful use of this with Wikidata URLs? I just fixed these. We should fix the regex to stop this. --- Jura 09:44, 1 April 2021 (UTC)

It’s used by a lot of properties to link to property proposal pages. I think this use is legitimate, but links to the main namespace don’t seem to be acceptable ever. What about excluding only mainspace links? —Tacsipacsi (talk) 22:46, 1 April 2021 (UTC)

• If it's doable, sure. Otherwise, I don't think we loose much if anything by removing it from the property pages. --- Jura 20:29, 2 April 2021 (UTC)

  Maybe ((?!wikidata.org/(wiki/|w/index.php\?title=)Q).)* could work to filter out most item usages based on the constraints of image (P18) (as an additional constraint rather than a replacement for the current one). —Tacsipacsi (talk) 23:01, 2 April 2021 (UTC)

  • If it works, let's go for it. --- Jura 08:19, 7 April 2021 (UTC)

    I’m not 100% sure, but went ahead and added it—worst case we have to revert. —Tacsipacsi (talk) 01:22, 8 April 2021 (UTC)

Oh, Krbot uses it to indicate how statements are inferred (sample). Forgot about that. That is actually useful. Maybe a complex constraint checking for the absence of inferred from (P3452) could to work. --- Jura 09:09, 8 April 2021 (UTC)

That tends to time out: [1], but finds some odd stuff. --- Jura 09:43, 8 April 2021 (UTC)

(Non-Wikimedia) import URL?

what if I imported something automatically from a html document with a url? I know I could use reference URL (P854) but that implies that the information was hand-picked by somebody and can be verified by looking at the website (which might not be the case, when the information was imported from hidden metadata). should there be a generic Import URL property? WikiProject Schemas has more than 50 participants and couldn't be pinged. Please post on the WikiProject's talk page instead. --Loominade (talk) 12:10, 7 June 2021 (UTC)

• No. This may have been the assumption earlier. Where did you get hand-picked from? --- Jura 12:21, 7 June 2021 (UTC)

Multiple format constraint violations not reported

Here we don’t see anything about The Accidental Spy (Q77950154) which wasn’t edited for months. What is wrong with updater? Incnis Mrsi (talk) 07:45, 17 August 2021 (UTC)
