How can i write the json schema if json has multiple data set

问题

I am new to this json schema , i am able to write json schema if it has only one data set like below

{
    "employees": [
        {
            "id": 1,
            "name": "aaa"
        }
}

example json-schema for this is

{   
        "type" : "object",
            "required" : ["employees"],
            "properties" : {        
                "employees" : { "type" : "Array",
                                "items" : [
                                "properties" : {
                                                    "id" : {"type" : "integer"},
                                                    "name" : {"type" : "string"},                                                   
                                                },
                                            "required" : ["id","name"]
                                            ]
                                }
                            }
}

but i got stuck to write json schema in ruby if we have multiple data sets

{
    "employees": [
        {
            "id": 1,
            "name": "aaa"
        },
        {
            "id": 2,
            "name": "bbb"
        },
        {
            "id": 3,
            "name": "cccc"
        },
        {
            "id": 4,
            "name": "ddd"
        },
        {
            "id": 5,
            "name": "eeee"
        }
    ]
}

can anyone please help me to write json schema if it has multiple data sets for same schema to validate the response body

Here is the schema you are looking for.

{
  "type": "object",
  "required": ["employees"],
  "properties": {
    "employees": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "id": { "type": "integer" },
          "name": { "type": "string" }
        },
        "required": ["id", "name"]
      }
    }
  }
}

You were really close. The items keyword has two forms. The value of items can be a schema or an array of schemas(1).

If items is a schema, it means that every item in the array must conform to that schema. This is the form that is useful in this case.

If the value of items is an array of schemas, it describes a tuple. For example, this schema ...

{
  "type": "array",
  "items": [
    { "type": "boolean" },
    { "type": "string" }
  ]
}

would validate this ...

[true, "foo"]
