我有一个JSON模式,表示一个点或多个点的几何形状。每个都在模式中通过“定义”进行定义:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "http://schema.my-site.org/geometry.json#",
"type": "object",
"oneOf": [
{
"allOf": [
{
"required": [
"type",
"coordinates"
]
},
{
"oneOf": [
{
"$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"
}
}
}
}
现在我想创建另一个模式,它利用了Point的定义。目前,我将Point和position的定义复制粘贴到属性“startPosition”和“endPosition”中,这样就可以使用了。但是,有没有一种方法可以仅从我的geometry.json模式中引用Point的定义呢?
注意:我只想在这里允许使用Point,而不是MultiPoint - 引用geometry.json会允许两者。
