So this is essentially a front-end to Wikidata?

Do I understand this correctly: every file on Commons is also a node (item?) on Wikidata, in the sense that it is assigned a QID, and thus you can start making statements about it — the structured data tab is essentially a front-end to the Wikidata database? The main difference to editing statements on Wikidata appears to be that this interface does not show the subject QID anywhere! Or are you using other URIs as resource identifiers? (Being explicit with such technical details would have helped me understanding what this was all about.)

Do you have any examples of statements relating one file to another? (I didn't encounter anything like that, browsing a few of the examples in the list of properties.) Practical application: relating different BSicons to each other. 88.129.117.158 14:59, 7 July 2024 (UTC)[reply]

No, each image does not have a QID. Each media item instead has an identifier consisting of "M" followed by its page ID, but as you say the interface mostly hides this. I don't think there's any way to relate files to one another directly; I've certainly never seen one. Notably, when Wikidata wants to refer to Commons files, it does it by name and not by using the "M" IDs. --bjh21 (talk) 15:31, 7 July 2024 (UTC)[reply]

Bot to remove duplicate statements

Hi folks, sometimes we end up with duplicate statements on files. This often happens when bots edit the same file twice. I set up bot to clean that up about once a month (code). It goes through the latest dump at https://dumps.wikimedia.org/commonswiki/entities/ (the copy on Toolforge) and removes any duplicate statements. It hashes the statement for quick processing so it doesn't catch cases (yet) like this one where the qualifiers are in different order. Multichill (talk) 20:29, 7 July 2024 (UTC)[reply]

List of bots involved

i think it'd be good for information, reference and documentation purposes to have a page that lists all bots and how they are involved in editing sdc. then we will know, whether a specific task in mind is already taken charge of, or if any bot malfunctions which tasks are not carried out, etc. RZuo (talk) 10:41, 6 August 2024 (UTC)[reply]

for example, i want to know now whether some bot is already in charge of migrating accidental addition of coordinate location (P625) to location of creation (P1071). RZuo (talk) 10:43, 6 August 2024 (UTC)[reply]

thx a lot.

also i made a mistake above. should be moving p625 to coordinates of the point of view (P1259) instead of p1071. RZuo (talk) 11:57, 6 August 2024 (UTC)[reply]

Cannot find haswbstatement:P1259

https://commons.wikimedia.org/w/index.php?search=haswbstatement:P1259 shows nothing despite File:Martin-Luther-Kirche Behringen 2024-04-09 03.jpg for example. why? this shouldnt be expected, right? RZuo (talk) 11:58, 6 August 2024 (UTC)[reply]

@RZuo: Ah yes, I remember looking at this before. I think CirrusSearch can only see properties whose values are text or Wikidata items. If you use the API to get cirrusbuilddoc for that page (API sandbox link) you'll find that statement_keywords contains source of file (P7482), copyright license (P275), copyright status (P6216), captured with (P4082), media type (P1163), and checksum (P4092), but not creator (P170), inception (P571), data size (P3575), or coordinates of the point of view (P1259). bjh21 (talk) 17:37, 6 August 2024 (UTC)[reply]

Inception for files where only Upload date is available

Is there a preferred way to add SDC inception (P571) claims for files with unknown creation date, but known {{Upload date}}? As far as I see, there's no "upload date" qualifier on Wikidata. Is it ok to simply use the upload date for inception (P571)? Fl.schmitt (talk) 20:30, 22 August 2024 (UTC)[reply]

@Fl.schmitt: how about "unknown value" with qualifier latest date (P1326) and the upload date. - Jmabel ! talk 04:30, 23 August 2024 (UTC)[reply]

@Jmabel - that's a good solution! I've used it already at Karte Bodensee Birnau.png - and {{Information}} is able to use latest date (P1326) as default if there's no date parameter - great! I wasn't able to set "unknown date" manually, but pywikibot was able to create such a claim with snaktype "somevalue". Fl.schmitt (talk) 07:16, 23 August 2024 (UTC)[reply]
