area for reference?

Hi, I recently have added some depicts statements to a historic photo of a city based on a news article that had detailed information about which buildings were where in a particular image. Is there a way to reference the news article? I added "reference URL" as a qualifier to Town view with mountains but I know on Wikidata there is a separate area for references.

References are particularly useful when different sources say different things about an image. As far as I can tell, the SDC team's initial assessment was that anything that was notable enough to be the subject of references would by that fact be notable enough to have its own Wikidata item, so any references could live there, and would therefore not be needed on Commons.

That assumption seems unsafe to me, and probably ought to be reconsidered. But some good real-life case studies would very much help make the argument. Jheald (talk) 01:06, 10 January 2020 (UTC)

Replacing a class with a specific instance

Tracked in Phabricator
Task T252292

The picture File:Aberdour Castle - geograph.org.uk - 112485.jpg had depicts (P180) -> castle (Q23413) on it. castle (Q23413) is a class. I replaced it with a specific instance of castle: Aberdour Castle (Q2145629). That seems like the right way to go or does anyone not agree with these kind of changes?

Let's assume for now we agree on this. We have quite a bit of data to get from the class to the instance:

• The image is in Category:Aberdour Castle which connects to Aberdour Castle (Q2145629) (which has instance of (P31) -> castle (Q23413))
• The image has coordinates so we query Wikidata for the nearest castle (Q23413)
• The image has location of creation (P1071) so we can use that to query Wikidata too (Scotland is a bit messy here, works better in other regions)

This could be used as input for a (semi-)automatic tool. Will probably work best for geographic locations with a bit of history like castles and churches. Any thoughts? Might work on it on the hackathon next weekend. Multichill (talk) 11:30, 3 May 2020 (UTC)

What happens when the subject doesn't have its own entry on wikidata? Need to ensure it doesn't get sucked into a nearby one that does.

Your fallbacks ('nearest location' and 'camera location') might fail even if the correct entries exist. We have Kingswear Castle (Q2969487) and Dartmouth Castle (Q675259), but a file like File:Kingswear Castle from Dartmouth Castle.jpg could get wrong one applied.--Nilfanion (talk) 11:24, 5 May 2020 (UTC)

@Nilfanion: In that case we should be creating a new item on Wikidata -- part of the value of Structured Data on Commons is that it allows us to identify where Commons Categories or other metadata has greater precision/information, or concepts than are available on Wikidata. @Multichill: I think what we need in part, for something like this, is to pick a high level concept that has a cradle model, and suggest the 4-5 close items related to that concept (churches or buildings will have a lot of these, by example) if that item isn't available, push the person into a workflow for a good data model for a new item. I got a comment recently on my talk page from someone who appears to be a bit overwhelmed by the approach of creating specific wikidata items -- leveraging cradle is probably going to be important here.

I also think that we need to demonstrate that the various Wikidata trees are useful for sorting concepts (i.e. taking something like public transportation and making it more specific i.e. Train part of (P361) public transport (Q178512) or some similar with specific modeling). I keep thinking about Andrew Lih's Wikidata Art Description explorer which constrains the depicts that can be used in the workflow significantly, to things used on other paintings -> maybe there is a way that you could preform the workflow for something like "car" to car models, etc. Sadads (talk) 12:43, 5 May 2020 (UTC)

Hackathon this weekend so I wrote the bot. Works quite well on the churches near me. Multichill (talk) 15:15, 9 May 2020 (UTC)

Adding the depicted location

Hi everyone, planning to import a lot of Geograph images and what to put exactly in depicts (P180) was brought up. Take for example File:Former Maxwell's Hotel, Walmgate - geograph.org.uk - 6000242.jpg. Here the robot added depicts (P180) -> Grade II listed building (Q15700834). It was requested I also add the depicted location so depicts (P180) -> York (Q42462). Of course people can change it to a more specific location after upload. Any objections?

Edit title

How to edit that title Sureshkumar1213 (talk) 08:27, 17 May 2020 (UTC)

@Sureshkumar1213: What title? - Jmabel ! talk 17:52, 17 May 2020 (UTC)

An image title when I typed its “tra “ it should be tea Sureshkumar1213 (talk) 06:19, 18 May 2020 (UTC)

I think User:Sureshkumar1213 is referring to File:Tra plantation.jpg. Rehman 07:46, 18 May 2020 (UTC)

Sureshkumar1213, go to File:Tra plantation.jpg. On top click on "More" → "Move" and enter the correct file name. --Achim (talk) 09:44, 18 May 2020 (UTC)

But, unsurprisingly, there is already a File:Tea plantation.jpg, so you'll need to pick something else, e.g. File:Tea plantation 02.jpg. - Jmabel ! talk 15:38, 18 May 2020 (UTC)

Shouldn't (?) prompt when uploading audio files

I uploaded an .oga audio sample file (Media:Sine sawtooth square waveforms.oga) and was prompted with a blue "Depicts" link that took me to an "Items portrayed in this file \ depicts" page. That was a little unexpected for an audio file. I skipped the step, but is there a policy for audio files? (Very nice upload process BTW, more structure, better reuse!) -- Skierpage (talk) 06:29, 9 June 2020 (UTC)

Similarly, after skipping the depicts step and publishing the audio file, I was prompted "Help make images more findable for everyone"... -- Skierpage (talk) 06:30, 9 June 2020 (UTC)

•  Comment Mmh, "depicts" is probably the wrong term, but there certainly should be an equivalent property for audio that connects for example File:La Brabançonne.oga with The Brabançonne (Q161539), File:Sine Wave 10Hz 30s.ogg with sine wave (Q207527) and File:D7100 shot sound at Continous High(7fps).wav with Nikon D7100 (Q5062127) and shutter (Q691823). Some kind of "audio recording of", reverse of audio (P51) ... --El Grafo (talk) 09:29, 9 June 2020 (UTC)

• I would use "depicts" after adding aliases applicable to audio and video files. --Jarekt (talk) 16:40, 9 June 2020 (UTC)
