Planned useThis SDC property will be used by file infoboxes on Commons to indicate which item should be used as basis for the infobox. It will have single-value constraint (Q19474404)
Robot and gadget jobsUser:JarektBot or others will populate this property based on current digital representation of (P6243): copying the values for 2D artworks and moving them for other objects.

Motivation[edit]

Property digital representation of (P6243) was originally proposed to be used with c:template:Artwork and be equivalent to {{Artwork|wikidata=...}}. It is being used that way right now by couple hundred thousand files and several templates. However other users had plans to use this property for 2D artworks only to indicate that the file is a faithful reproductions of two-dimensional works of art that meets requirements of c:template:PD-Art or to tag files where wikidata relative position within image (P2677) properties are valid. As a result Wikidata:Property proposal/Digital representation of proposal when finally approved was ambiguous about its purpose. Ever since, most of the discussions at Property_talk:P6243 revolve around multiple visions different users have for this property. Based on Property_talk:P6243#2D_vs._3D discussion it seems like the best solution is to split digital representation of (P6243) into at least 2 properties: one to be used by Commons infobox templates and one for digitizations of 2D artworks. --Jarekt (talk) 04:36, 28 September 2020 (UTC)[reply]

How is it different from other properties:

In general, getting a new single-purpose property with name linking it to its purpose is important, since adding this property would affect the displayed metadata, and should be independent of any other task.--Jarekt (talk) 12:53, 28 September 2020 (UTC)[reply]

Discussion[edit]

Mike, Can you provide details on your proposal? How would it work? Depict statements seem particularly badly suited for this task:
If depicts (P180) is used correctly (i.e., for the specific things depicted, not random things), then it works well. E.g., see commons:File:Jodrell Bank Mark II 5.jpg, which uses commons:Template:Structured Data to pull out information about multiple telescopes in the image. The same should work fine in the cases here. Thanks. Mike Peel (talk) 18:28, 5 October 2020 (UTC)[reply]
However depicts (P180) is usually not used correctly and yes you can handcraft an image where it works but for great many images it does not. c:template:Artwork uses depicts (P180) to find and list depicted people. That code was crashing on some pages due too many depict statements and taking too long. I had to limit it to only first 50 depicts for which I was looking up instance of (P31). That is why "Infobox based on" only allows a single value. The purpose of depict is to list depicted people, places, objects, etc. and purpose of "Infobox based on" is to choose a single item to base the infobox on. Those 2 purposes are very different. We already tried to use a single property for 3 different tasks: digital representation of (P6243) and as a result it does not work well for any of them. --Jarekt (talk) 00:56, 7 October 2020 (UTC)[reply]
Sure --Jarekt (talk) 02:09, 1 November 2020 (UTC)[reply]
It would not work well with depicts (P180) as you might have large number of those and it might be a mess to find the depict with the qualifier. main subject (P921) might work because there should be only one of those. Tools like c:User:Magnus Manske/sdc tool.js which I currently use to add digital representation of (P6243) to files, do not support qualifiers. Is main subject (P921) appropriate for files which show image details or for PDF files which we would link to items? --Jarekt (talk) 01:28, 20 April 2021 (UTC)[reply]

Switched to using main subject (P921) on Commons so I think we can close this one. Multichill (talk) 21:07, 14 April 2022 (UTC)[reply]

In that case I'm closing this discussion. If I made a mistake please feel free to revert my closing. Thanks. RPI2026F1 (talk) 16:30, 4 January 2023 (UTC)[reply]
