JSON Schema - Required object by value - json

Question

it is possible to validate required values in a JSON Schema?
I have the following JSON:
{
"genericData": [
{
"name": "field_one",
"value": "data_one"
},
{
"name": "field_two",
"value": [
"array_data_one",
"array_data_two"
]
},
{
"name": "field_three",
"value": {
"attr_one": "some_data",
"attr_two": "more_data"
}
}
]
}
For validating the objects in the array i have the following JSON Schema:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"properties": {
"genericData": {
"type":"array",
"minItems": 2,
"items": [
{
"type": "object",
"if": {
"properties": {
"name": {
"enum": [
"field_one"
]
}
}
},
"then": {
"properties": {
"name": {
"type": "string"
},
"value": {
"type": "string"
}
}
}
},
{
"type": "object",
"if": {
"properties": {
"name": {
"enum": [
"field_two"
]
}
}
},
"then": {
"properties": {
"name": {
"type": "string"
},
"value": {
"type": "array",
"minItems": 1,
"items": [
{
"type": "string"
}
]
}
}
}
},
{
"type": "object",
"if": {
"properties": {
"name": {
"enum": [
"field_three"
]
}
}
},
"then": {
"properties": {
"name": {
"type": "string"
},
"value": {
"type": "object",
"properties": {
"attr_one": {
"type": "string"
},
"attr_two": {
"type": "string"
}
},
"required": [
"attr_one",
"attr_two"
]
}
}
}
}
]
}
}
}
Now my question is: Is it possible to set the objects e.g. with the names "field_one" and "field_two" as required? I tried to set the propertie "name", in the "then" clause as required, but this has no impact!
Thanks,
Andreas

Answer 1

I found the solution. The keywords "allOf" and "contains" in combination with "pattern" did what i want:
...
"genericData": {
"type":"array",
"minItems": 2,
"allOf": [
{
"contains": {
"type": "object",
"properties": {
"name": {
"type": "string",
"pattern": "^field_one$"
}
}
}
},
{
"contains": {
"type": "object",
"properties": {
"name": {
"type": "string",
"pattern": "^field_two$"
}
}
}
}
],
"items": [
{
"type": "object",
"if": {
"properties": {
"name": {
"enum": [
"field_one"
]
}
}
},
...
