new Constraint

@User:Lockal: In this edit you just added a new constraint. Can you explain what it means as I do not understand it. --Jarekt (talk) 21:29, 30 September 2020 (UTC)

@Jarekt: It means that this property should be used only on items, not on other entity types like properties or Commons files. This is obviously wrong and the result of a not careful enough bot action; I’ve expanded it to allow Commons files (probably it shouldn’t be used on other types of entities indeed). —Tacsipacsi (talk) 00:14, 1 October 2020 (UTC)

@Tacsipacsi:, thank you, you are 100% correct, I ignorantly overlooked few of MediaInfo external identifiers due to they are non-queryable via WDQS (added statements were based on usage from WDQS and P31/P279*), with exceptions, I've handled manually (I targeted to find lexeme-only properties, that were incorrectly used in Wikidata items). Luckily, there are only few external identifiers currently used in WCQS. I'll handle them manually too. --Lockal (talk) 08:26, 1 October 2020 (UTC)

Check regular expression - fix needed

In the documentation, the check is changed to allow 20[012]... The controls below the documentation still mentions 20[0-1]...

I came across this whilst adding a ticket]. Who can fix this? Thanks in advance, RonnieV (talk) 11:21, 29 January 2021 (UTC)

@RonnieV: There’s a regular expression statement and there’s another, independent, constraint statement. Only the former was updated before, now I’ve adjusted the latter as well. —Tacsipacsi (talk) 15:25, 29 January 2021 (UTC)

@Tacsipacsi: I could not find that one (did not scroll down to the Constraints-section). Learned something, so thanks for that, and for solving it. RonnieV (talk) 15:41, 29 January 2021 (UTC)

I had a new look at the expression, and it seems to me it could even be shorter. There were now two parts handling years starting with 2. RonnieV (talk) 17:57, 29 January 2021 (UTC)
