$ref 的 JSONSchema 验证失败（草案 v3）

Question

我已经按照 v3 规范草案创建了一个 JSON 架构。架构如下所示：

{
"$schema": "http://json-schema.org/draft-03/schema#",
"additionalProperties": false,
"type": "object",
"properties": {
    "ExecutionPlanList": {
        "type": "array",
        "items": [{
            "type": "object",
            "properties": {
                "model": {
                    "required": true,
                    "properties": {
                        "featureList": {
                            "required": true,
                            "items": {
                                "properties": {
                                    "featureName": {
                                        "type": ["string", "null"]
                                    },
                                    "featureType": {
                                        "type": "string"
                                    }
                                },
                                "type": "object"
                            },
                            "type": "array"
                        },
                        "modelId": {
                            "required": true,
                            "type": "string"
                        }
                    },
                    "type": "object"
                },
                "cascadeSteps": {
                    "required": false,
                    "items": {
                        "properties": {
                            "binaryModel": {
                                "$ref": "#/properties/ExecutionPlanList/items/properties/model",
                                "required": true
                            },
                            "threshold": {
                                "required": true,
                                "default": "0.0",
                                "maximum": 100.0,
                                "type": "number"
                            },
                            "backupModel": {
                                "$ref": "#/properties/ExecutionPlanList/items/properties/model",
                                "required": true
                            }
                        }
                    },
                    "type": "array"
                },
                "marketplaceId": {
                    "required": true,
                    "type": "integer"
                }
            }
        }]
    }
},
"required": true
}

本质上，executionPlanList包含model和cascadeStep的列表，每个cascadeStep包含两个带有编号的model。所以我试图在 cascadeStep 中重新使用模型的模式，但是验证 (https://www.jsonschemavalidator.net/) 失败 Could not resolve schema reference '#/properties/ExecutionPlanList/items/properties/model'.

如有任何关于此架构错误的指示，我们将不胜感激。

Answer 1

应该是'#/properties/ExecutionPlanList/items/0/properties/model'

顺便说一下，架构仅验证第一项。

Answer 2

如何添加一个 'definitions' 并像这样引用：

{
"$schema": "http://json-schema.org/draft-03/schema#",
"additionalProperties": false,
"type": "object",
"definitions": {
      "model": {
          "required": true,
          "properties": {
              "featureList": {
                  "required": true,
                  "items": {

                            },
                            "backupModel": {
                                "$ref" : "#/definitions/model",
                                "required": true
                            }
                        }
