How to use definitions in JSON schema (draft-04)
Solution 1:
I think the recommended approach is the one shown in Json-Schema web, Example2. You need to use an enum to select schemas "by value". In your case it would be something like:
{
"type": "object",
"required": [ "results" ],
"properties": {
"results": {
"type": "array",
"items": {
"oneOf": [
{ "$ref": "#/definitions/person" },
{ "$ref": "#/definitions/company" }
]
}
}
},
"definitions": {
"person": {
"properties": {
"type": { "enum": [ "person" ] },
"name": {"type": "string" },
"dateOfBirth": {"type":"string"}
},
"required": [ "type", "name", "dateOfBirth" ],
"additionalProperties": false
},
"company": {
"properties": {
"type": { "enum": [ "company" ] },
. . .
}
}
}
}
Solution 2:
Sorry,
I don't get the point. The question is about the 'dependencies' keyword which is part of the last JSON Schema specification, right?
I do not find 'dependencies' in the accepted answer (?)
It is briefly explained in the last draft. But http://usingjsonschema.com explained both property and definition dependencies in the book:
http://usingjsonschema.com/assets/UsingJsonSchema_20140814.pdf
start at page 29 (see, explained at page 30)
"dependencies": {
"shipTo":["shipAddress"],
"loyaltyId":["loyaltyBonus"]
}
