Simplify array of objects with children using JQ - jq

Question

From Wikidata, I get the following json:
# Sparql query
query=$(cat ./myquery.sparql)
response=$(curl -G --data-urlencode query="${query}" https://wikidata.org/sparql?format=json)
echo "${response}" | jq '.results.bindings'
[
{
"language": {
"type": "uri",
"value": "https://lingualibre.org/entity/Q100"
},
"wikidata": {
"type": "literal",
"value": "Q36157"
},
"code": {
"type": "literal",
"value": "lub"
}
},
{
"language": {
"type": "uri",
"value": "https://lingualibre.org/entity/Q101"
},
"wikidata": {
"type": "literal",
"value": "Q36284"
},
"code": {
"type": "literal",
"value": "srr"
}
}
]
I would like to have the keys directly paired with their values, such as :
[
{
"language": "https://lingualibre.org/entity/Q100",
"wikidata": "Q36157",
"iso": "lub"
},
{
"language": "https://lingualibre.org/entity/Q101",
"wikidata": "Q36284",
"iso": "srr"
}
]
I currently have a non-resilient code, which will break whenever the key names change :
jq 'map({"language":.language.value,"wikidata":.wikidata.value,"iso":.code.value})'
How to pair the keys with their values in a resilient way (not naming the keys) ?
I want to "prune" the child objects so to only keep the value.

You could use map_values which works like the outer map but for objects, i.e. it retains the object structure, including the field names:
jq 'map(map_values(.value))'
[
{
"language": "https://lingualibre.org/entity/Q100",
"wikidata": "Q36157",
"code": "lub"
},
{
"language": "https://lingualibre.org/entity/Q101",
"wikidata": "Q36284",
"code": "srr"
}
]
Note that this solution lacks the name conversion from code to iso.
