Json generic object type - json

Question

I'd like to define an object something like this, to map to something like a java Map (but not exactly, since this needs to interface with typescript as well). Ultimately, what I'm trying to figure out is how to declare the <T> type of something (say Dict<MyObj>) in another object (if this is even possible):
(this is obviously not a valid json schema)
{
"type": "object",
"javaType": "some.package.base.DictKeyValuePair",
"properties": {
"key": { "type": "string" },
"value": { "type": "<T>" }
}
}
which would be referenced in other json schemas something like this:
{
"type": "object",
"javaType": "some.package.base.Dict",
"properties": {
"key": { "type": "string" },
"value": { "type": "<T>" },
"keValuePairs": {
"type": "array",
"items": {
"$ref": "DictKeyValuePair.json",
"genericType": "<T>"
}
}
}
}
finally being used in an object similar to this:
{
"type": "object",
"javaType": "some.package.SomeObject",
"properties": {
"someDict": {
"$ref": "Dict.json",
"genericType": "SomeObjectOrSimpleType"
}
}
}
So... is this possible in a json schema?

Answer 1

It is possible to do something like that using json-schema but you need to define the schemas, take a look to this samples:
http://json-schema.org/learn/examples/address.schema.json
{
"$id":"https://example.com/address.schema.json",
"$schema":"http://json-schema.org/draft-07/schema#",
"description":"An address similar to http://microformats.org/wiki/h-card",
"type":"object",
"properties":{
"post-office-box":{
"type":"string"
},
"extended-address":{
"type":"string"
},
"street-address":{
"type":"string"
},
"locality":{
"type":"string"
},
"region":{
"type":"string"
},
"postal-code":{
"type":"string"
},
"country-name":{
"type":"string"
}
},
"required":[
"locality",
"region",
"country-name"
],
"dependencies":{
"post-office-box":[
"street-address"
],
"extended-address":[
"street-address"
]
}
}
