Understanding the Generated JSON Schema

Understanding the generated JSON Schema

If you've turned on the JSON Schema generation, Jsonix Schema Compiler will produce one more JSON Schema files for each your modules according to the configuration.

Single-mapping module

We'll start with a single-maping module, that is, a module which contains just one mapping (see Modules and Mappings for more information).

The JSON Schema for a single-mapping module will contain:

• the id of the schema.
• the definitions sections which declares complex and enum types;
• the anyOf section which lists possible top-level elements as qualified name/expected value type pair.

Here's what it looks like:

{
    "id":"PurchaseOrder.jsonschema#",
    "definitions":{
        "MyComplexType":{ "type":"object", ... },
        "MyEnumType":{ "type":"string", ... },
        ...
    },
    "anyOf":[
        {
            "type":"object",
            "properties":{
                "name":{
                    "$ref":"http://www.jsonix.org/jsonschemas/w3c/2001/XMLSchema.jsonschema#/definitions/QName"
                },
                "value":{
                    "$ref":"#/definitions/MyComplexType"
                }
            },
            "elementName":{
                "localPart":"myComplexElement",
                "namespaceURI":""
            }
        },
        ...
    ]
}
