Question
How to get the "depicts" of a given image, as JSON, using either a wikimedia-android-data-client library call or a REST HTTP request?

Answer 1

You can use some of the Wikibase APIs (exactly which or how is not well-documented at the moment, I think). E.g.
https://commons.wikimedia.org/w/api.php?action=wbgetclaims&format=jsonfm&entity=M78893847
{
"claims": {
"P180": [
{
"mainsnak": {
"snaktype": "value",
"property": "P180",
"hash": "7754bb4b4dcf94dd0a6b8524351b22df21328a88",
"datavalue": {
"value": {
"entity-type": "item",
"numeric-id": 12280,
"id": "Q12280"
},
"type": "wikibase-entityid"
},
"datatype": "wikibase-item"
},
"type": "statement",
"id": "M78893847$bf7f116a-4d08-0426-0e81-c9552a89fa63",
"rank": "preferred"
},
{
"mainsnak": {
"snaktype": "value",
"property": "P180",
"hash": "8ed7e126588c21d3cf88387d5ee875d528c00a74",
"datavalue": {
"value": {
"entity-type": "item",
"numeric-id": 1021645,
"id": "Q1021645"
},
"type": "wikibase-entityid"
},
"datatype": "wikibase-item"
},
"type": "statement",
"id": "M78893847$7830fc04-4a1e-f289-93bc-69d6bbf3b7fd",
"rank": "normal"
}
]
}
}
78893847 being the page ID which you can get via the query API:
https://commons.wikimedia.org/w/api.php?action=query&format=jsonfm&formatversion=2&titles=File%3AMomoyo-brug%20in%20Shibaura%2C%20gezien%20richting%20het%20zuidoosten%2C%20-15%20maart%202019.jpg
{
"batchcomplete": true,
"query": {
"pages": [
{
"pageid": 78893847,
"ns": 6,
"title": "File:Momoyo-brug in Shibaura, gezien richting het zuidoosten, -15 maart 2019.jpg"
}
]
}
