Infer Wikimedia Commons category from Wikidata to show photos (P373)

[dbogdanov]

As I understand, currently OsmAnd shows photos found on Wikidata (image) and Wikimedia Commons following the wikidata and wikimedia_commons tags for a node.

However, there will be many situations when there is no wikimedia_commons tag assigned, but it is possible to infer the associated Commons category from Wikidata.

Example:

• https://www.openstreetmap.org/node/7096334253
• https://www.wikidata.org/wiki/Q11953719
• https://commons.wikimedia.org/wiki/Category:Tur%C3%B3_del_Mar

I am not sure if the wikimedia_commons tag is commonly used on OSM, but I would expect the links from Wikidata to Wikimedia Commons to be better maintained.

Proposal: Look for wikimedia_commons and wikidata tags and if wikimedia_commons is not present look for Commons category on Wikidata to form the pool of photos to show.

Well for now it would require to process maps with Wikidata access cause OsmAnd now displays only images that are provided inside OSM tags. It's one extra step is needed online to get image from wikidata.

The image shown is already taken online from Wikidata. The only difference would be to also follow the link from Wikidata to Wikimedia Commons.

Another possibility would be that during map creation, Wikimedia Commons and Wikipedia tags are taken from the Wikidata object and then written into the tags if not already present.

OsmAnd now displays only images that are provided inside OSM tags

I was wondering what OSM tags OsmAnd was using to display photos and found this thread.
What I notice is that the image tag is used, but not the wikimedia_commons tag (at least with OsmAnd 4.1.1 on IOS).
It's a pity because the wikimedia_commons tag is the one that is recommended at the top of the list in the OSM wiki to link a photo gallery.
Would it be possible to add the use of this OSM tag in OsmAnd?
Thanks in advance-

@clwacker you probably want to open separate issue for ios cause this issue is fixed
At least for https://www.openstreetmap.org/node/7096334253

Currently only one image is shown. What about having a way to access all photos available for the POI? This could be done as a clickable "more photos" that links to the appropriate Wikimedia Commons category.

Yes, that exactly what I hoped to have in OsmAnd and asked a few days ago in #13548

Seconding this request for improved image pulling. Presently, if there is only a wikimedia_commons key, then all pictures are pulled. However, if there is both a wikimedia_commons key and a wikidata key, then only the image from the wikidata, if it even exists, is displayed. As well, if there is only a wikidata key available on the OSM entity, then only the image from wikidata is displayed (if it exists), even if there is a Commons Category statement on the wikidata entry.

OsmAnd~ 4.6.0#1007m, released: 2023-11-10
6 tested nodes with wikidata=* tag show pictures from wikimedia commons as expected.

• ToDo is missed

[vshcherb]

To do:

All OSM objects having tag wikidata or wikipedia or wikimedia_commons like https://www.openstreetmap.org/node/7096334253
should display following images:

1. Images from wikimedia_commons attached to OSM - https://commons.wikimedia.org/wiki/Category:Tur%C3%B3%20del%20Mar?uselang=en like https://www.openstreetmap.org/node/7096334253
2. Images from wikidata directly https://www.wikidata.org/wiki/Q11953719 property P18
3. Images from wikidata https://www.wikidata.org/wiki/Q11953719 wikimedia commons - propery https://www.wikidata.org/wiki/Property:P373
4. Images that has link to referenced wikidata - https://commons.wikimedia.org/wiki/File:Siilinkari.jpg reference https://www.wikidata.org/wiki/Property:P180

Merged with task - #13926
