我有一个json模式,将几何体表示为Point或MultiPoint。每个都在"定义":
中的模式中定义{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "http://schema.my-site.org/geometry.json#",
"type": "object",
"oneOf": [
{
"allOf": [
{
"required": [
"type",
"coordinates"
]
},
{
"oneOf": [
{
"$ref": "#/definitions/Point"
},
{
"$ref": "#/definitions/MultiPoint"
}
]
}
]
}
],
"definitions": {
"Point": {
"title": "Point",
"type": "object",
"properties": {
"type": {
"enum": [
"Point"
]
},
"coordinates": {
"$ref": "#/definitions/position"
}
}
},
"MultiPoint": {
"title": "MultiPoint",
"type": "object",
"properties": {
"type": {
"enum": [
"MultiPoint"
]
},
"coordinates": {
"$ref": "#/definitions/positionArray"
}
}
},
"position": {
"type": "array",
"minItems": 2,
"maxItems": 2,
"additionalItems": false,
"items": [
{
"type": "number"
},
{
"type": "number"
}
]
},
"positionArray": {
"type": "array",
"items": {
"$ref": "#/definitions/position"
}
}
}
}
现在我想制作另一个使用Point定义的模式。目前,我在属性" startPosition"中复制了Point和position的定义。和" endPosition"它的工作原理。但是有没有办法如何从我的geometry.json模式中引用Point的定义?
注意:我只想允许在这里使用Point而不是MultiPoint - 而geometry.json ref将允许两者都使用。
{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "http://schema.my-site.org/myitem.json#",
"type": "object",
"additionalProperties": false,
"required": [
"myproperty"
],
"properties": {
"myproperty": {
"type": "array",
"minItems": 0,
"items": {
"type": "object",
"additionalProperties": false,
"properties": {
"id": {
"type": "string"
},
"startPosition": {
"geometry": {
"required": [
"type",
"coordinates"
],
"title": "Point",
"type": "object",
"properties": {
"type": {
"enum": [
"Point"
]
},
"coordinates": {
"type": "array",
"minItems": 2,
"maxItems": 2,
"additionalItems": false,
"items": [
{
"type": "number"
},
{
"type": "number"
}
]
}
}
}
},
"endPosition": {
"geometry": {
"required": [
"type",
"coordinates"
],
"title": "Point",
"type": "object",
"properties": {
"type": {
"enum": [
"Point"
]
},
"coordinates": {
"type": "array",
"minItems": 2,
"maxItems": 2,
"additionalItems": false,
"items": [
{
"type": "number"
},
{
"type": "number"
}
]
}
}
}
}
}
}
}
}
}

我自己没有测试过,但根据this,您可以使用JSON pointers:
在文件geometry.json中:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "http://schema.my-site.org/geometry.json",
"type": "object",
"definitions": {
"Point": { ...},
"MultiPoint": {...}
}
}
在文件myitem.json中:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "http://schema.my-site.org/myitem.json#",
"type": "object",
"properties": {
"point": {
"$ref": "http://schema.my-site.org/geometry.json#definitions/Point"
}
}
}
