What properties to use to mark media files as l-r-stereoscopic, having nude content, having sexual content?[edit]

I like to add properties to my uploaded files for stereoscopic content, for containing nude depictions, for containing sexual depicitions. What properties would I use for that? C.Suthorn (@Life_is@no-pony.farm - p7.ee/p) (talk) 22:08, 16 December 2023 (UTC)[reply]

Steroscopy as a technique is stereo photography (Q17165350), but oddly there doesn't seem to be a property for photographic technique (Q1439691).
For the others, I'm guessing they can be done with depicts: nudity (Q10791), sexual intercourse (Q5873), cunnilingus (Q8402), fellatio (Q8401), etc.- Jmabel ! talk 23:55, 16 December 2023 (UTC)[reply]
While adding depicts is useful (and as time allows I will do that), but I was more looking for a type of rating. DSA/DMA is coming and WM is affected by it. Ideally I would like to add the information that is needed in the form a future MW content rating system will need it, or at least in a way that it can be automagically translated into the form that future sysetm will need it.

I have just created stereo photograph (Q123906082), which may be used with has characteristic (P1552). Categorisation of pornographic images in the manner suggested would require a wider discussion and consensus on Commons.

There also a whole set of projections that really should be modelled, which I think it is good to have a discussion about.
For instance, stereoscopy can be lr, rl, tb, interlaced, red/green shift etc. And for 360 photography/videography you have projections like equirectangular, cylindrical, cube, eac etc, which in turn can be encoded with stereoscopy as well. I've been meaning to open a discussion about this, but haven't gotten around to it yet. —TheDJ (talkcontribs) 10:08, 19 December 2023 (UTC)[reply]
Agree to that. Also wiggle stereoscopy. But the majority of stereoscopic images are probably lr. Either PD stereo cards from the past, and images from @VasuVR an me. C.Suthorn (@Life_is@no-pony.farm - p7.ee/p) (talk) 19:47, 23 December 2023 (UTC)[reply]
Thank you for tagging in this discussion, @C.Suthorn. My earlier stereoscopic photographs I have tagged with stereoscopy (Q35158), under "depicts" (P162) - may not be really appropriate (example Flowers at Bristol ). Any final suggestion can be applied to all of my stereoscopic L-R images, which are in the category Category:Files (stereoscopic) by VasuVR. Please tag me with final decisions, suggestions. Thank you. VasuVR (talk, contribs) 08:59, 24 December 2023 (UTC)[reply]
Depicts is certainly wrong for photographic technique. - Jmabel ! talk 09:45, 24 December 2023 (UTC)[reply]

what property to mark a file that contains use of german sign language?[edit]

How do I add info about use of german sign language to a foto or to a video? C.Suthorn (@Life_is@no-pony.farm - p7.ee/p) (talk) 17:18, 25 December 2023 (UTC)[reply]

1. Click "Add statement".
2. Add property language of work or name (P407).
3. Add item German Sign Language (Q33282).

Aerial photographs[edit]

How do you identify whether an aerial photo was taken from an airplane, a balloon or a drone? XRay 💬 19:20, 1 February 2024 (UTC)[reply]

By "identify" I assume you mean "indicate (if known)", not how you work it out from looking at the photo (which often you can't). - Jmabel ! talk 20:28, 1 February 2024 (UTC)[reply]
You're right, indicate. --XRay 💬 20:38, 1 February 2024 (UTC)[reply]
I'm a little surprised we don't have a property corresponding to photographic technique (Q1439691). Then you could set the value of that to drone photography (Q12033087) (for example). Can anyone see a way to do an an equivalent of that? - Jmabel ! talk 20:36, 1 February 2024 (UTC)[reply]
Please have a look to Category:Aerial photographs by camera vehicle. How to model camera vehicle? --XRay 💬 20:42, 1 February 2024 (UTC)[reply]
Slightly off topic, but shouldn't Category:Aerial photographs by Smart Drone‎ be a subcat of Category:Unmanned aerial vehicle aerial photography? - Jmabel ! talk 01:56, 2 February 2024 (UTC)[reply]
@XRay: It has been suggested on Wikidata that we could use genre (P136) with drone photography (Q12033087). - Jmabel ! talk 16:26, 4 February 2024 (UTC)[reply]
This is logical and understandable. However, another value that is often used is more general: aerial photography (Q191839). You can't tell from the value whether it was a drone, an airplane, a hot air balloon or something else. --XRay 💬 18:14, 4 February 2024 (UTC)[reply]
captured with (P4082) exists for drones and the like. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:34, 4 February 2024 (UTC)[reply]

How to depict flexed muscles with expression, gesture or body pose (P6022)?[edit]

How do you recommend modelling flexed muscles with expression, gesture or body pose (P6022) for photos like this one or other photos in Category:Biceps brachii? ? Lovelano (talk) 03:12, 5 March 2024 (UTC)[reply]

instead of p6022, try
depicts (P180)
Preferred rank Erin Cummings

Garbage "tags" still being added in bulk[edit]

So this is what the universe looks like. And NASA.

Well-intentioned users are still being encouraged by apps to stuff the depicts statement with garbage "tag" values.

For instance this recent edit tagged the above image of part of the surface of the Earth from the ISS as depicting the ISS, "Expedition 22", "outer space", NASA, and the universe. The edit summary includes #suggestededit-add-tag 1.0" and the edit is tagged "Mobile edit Mobile app edit Android app edit Suggested Edits edit".

How do we get this stopped? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 17:21, 10 March 2024 (UTC)[reply]

Seconding this request. I find myself clearing crap like this off of the file pages of my pictures every day or two. How much of this must be accumulating on file pages that no one is watching? - Jmabel ! talk 18:33, 10 March 2024 (UTC)[reply]
Strange, I never had crap tags added to the files I uploaded (not to say it is impossible, but it never happened to my pictures). Ymblanter (talk) 18:35, 10 March 2024 (UTC)[reply]
Better instructions in the apps or a visual example? I'm speculating here but if people see a blank page they have no idea how to use correct properties so something to steer people towards right approach would be useful? Let's say people want to add "creation date" but the property they need is called "inception" - something to steer people towards right property might be useful. Another thing entirely is how well-made the translations for different languages are.. Ipr1 (talk) 21:29, 21 March 2024 (UTC)[reply]
Imagine being a new user and you see an empty box on the page, so maybe you would assume that is where you put things and magic happens. Adding a statement? A claim? A qualifier? It takes a more experienced users to know what those are and how they relate to values they see on the page. Ipr1 (talk) 21:40, 21 March 2024 (UTC)[reply]
I frequently have crap tags added to my pictures, which I remove.
It isn't a matter of better teaching clueless newbies what is a good value to add as a "depicts" on someone else's picture. It's a matter of not encouraging clueless newbies to add these. - Jmabel ! talk 07:01, 22 March 2024 (UTC)[reply]

Maintenance category broken?[edit]

Quality images missing SDC Commons quality assessment currently has over 14,000 files in it. But from a random sample of 15 files in this category, I found 9 to actually already include the statement. Clearing the category's cache didn't help. This makes that category not really helpful any more. Any ideas, what could cause this problem?

@Mike Peel, @Dschwen: could QICbot possibly set Commons quality assessment (P6731) Wikimedia Commons quality image (Q63348069) upon promotion and make this maintenance category obsolete? MB-one (talk) 10:34, 11 March 2024 (UTC)[reply]

This was being done by @Multichill's bot, I'm not sure why that stopped? I haven't figured out how to set SDC values using pywikibot/the API yet, it's on my to-do list, but I'm not sure when I'll get to it. Thanks. Mike Peel (talk) 11:27, 11 March 2024 (UTC)[reply]
Indeed https://commons.wikimedia.org/w/index.php?sort=last_edit_desc&search=-haswbstatement%3AP6731+hastemplate%3AQualityImage+filetype%3Abitmap&title=Special%3ASearch&profile=advanced&fulltext=1&advancedSearch-current=%7B%22fields%22%3A%7B%22hastemplate%22%3A%5B%22QualityImage%22%5D%2C%22filetype%22%3A%22bitmap%22%7D%7D&ns6=1 shows far fewer results and no false positives so far. MB-one (talk) 18:46, 11 March 2024 (UTC)[reply]
@MB-one and Mike Peel: Jobs User:BotMultichillT used to run have been disabled by the Wikimedia Foundation, see phab:T319912. Didn't really have the motivation to fix it yet. Multichill (talk) 17:40, 15 March 2024 (UTC)[reply]
@Multichill: so do I understand correctly that you decided that with this change of technical environment, you are abandoning all your bot tools and have no interest in migrating them? Are you willing to work at all with some other user who might be interested in migrating them? I suspect there are a fair number of these someone would like not to lose. - Jmabel ! talk 18:40, 15 March 2024 (UTC)[reply]
I've had to convert several of my bot scripts over to the new system (e.g., setup script for the venv, then new job submission script, with the run script loading the venv), would be happy to help here if you need. Although, this is why I run most of my scripts on an environment I have full control over... Thanks. Mike Peel (talk) 18:59, 15 March 2024 (UTC)[reply]

Some more examples might be helpful.[edit]

I've been adding SDC, but I'm really not sure if I'm doing it right. Could I have some feedback, and is there a place for more examples? (I looked at Commons:Structured data/Modeling/Depiction.)

See File:Cape Air ticket counter at MWA airport.jpg; I've described it as a ticket counter, which is part of the specific airport. Is that the best way to express this?

I've added a captured with statement for the drone model in File:Caspersen Beach aerial view.jpg, but this is showing a warning. An I doing it wrong, or should this be automatically populated from EXIF or categories like Category:Taken with DJI FC220 anyway? (Is that happening in some cases but not others?)

For construction equipment like File:Caterpillar backhoe loader at construction site in Sunnyvale, back view.jpg, I get a warning when I say it depicts the generic type of equipment, and specify the make as the manufacturing company. I'm also not sure how to specify the model number. See also File:Google self-driving Lexus RX450h rear view.gk.jpg; specifying the make and model of a car seems reasonable, but I get a warning with the make and didn't know how to specify the model.

Thanks in advance to anyone who can help. I'm intrigued by the tools, but I feel like I'm using them... not quite right. grendel|khan 11:11, 15 March 2024 (UTC)[reply]

Subtitles hardcoded into video track?[edit]

Secretary Janet Yellen on the Child Tax Credit

maybe there should be some properties about subtitles embedded in the video track? in contrast to subs from timed text files? RZuo (talk) 19:31, 23 March 2024 (UTC)[reply]

What properties to use to state conservation status and types of damage of old photographs[edit]

Hello! I'm trying to add structured data to several old photographs of my city we've uploaded to Commons, like this one: https://commons.wikimedia.org/wiki/File:Plaza_Constituci%C3%B3n_-_0001FMHC.tif I have a big dataset several datapoints available, including "conservation status" (good, bad or regular) and "types of damage" (like silver mirroring Q112581162, mutilation, scratchs, inscriptions...). Apparently all these data follows the General International Standard Archival Description conventions, but I still can figure out which Wikidata properties should I use. Any ideas? Thanks!
