我正在尝试使用 JSON 调整产品的本体及其属性。下面提到的 JSON 结构是我正在考虑的。
Each Product (Concept) has two types of properties: 1. Data Properties 2. Object Properties
使用 Protege 时这些属性的典型定义如下 SO Thread :
In Protégé there are are different tabs for creating Object Properties and Datatype Properties. If a property should relate individuals to individuals, then it needs to be an object property, and if it relates individuals to literals, then it needs to be a datatype property.
我认为每个属性都具有以下属性:
name: string
url: string
type: dataprop or objprop
objPropSource: available only for Objproperties
我已经制定了一个小的递归 JSON,如下所示:
{
"name": "chair",
"url": "http://namespace.org#chair",
"type": "main",
"properties": [
{
"name": "height",
"url": "http://namespace.org#height",
"type": "dataprop"
},
{
"name": "width",
"url": "http://namespace.org#width",
"type": "dataprop"
},
{
"name": "horizontalsurface",
"url": "http://namespace.org#horizontalsurface",
"type": "objprop",
"objPropSource": "http://namespace.org#hasHorizontalSurface",
"properties": [
{
"name": "Legislation",
"url": "http://namespace.org#legislation",
"type": "objprop",
"objPropSource": "http://namespace.org#compliesWithLegislation",
"properties": [
{
"name": "hasLegislationName",
"url": "http://namespace.org#hasLegislationName",
"type": "dataprop"
}
]
}
]
},
{
"name": "legislation",
"url": "http://namespace.org#legislation",
"type": "objprop",
"objPropSource": "http://namespace.org#compliesWithLegistion",
"properties": [
{
"name": "hasLegislationName",
"url": "http://namespace.org#hasLegislationName",
"type": "dataprop"
}
]
}
]
}
在某种程度上,结构为椅子提供了一个二叉树,它具有 height
、width
等作为 dataproperties 和 horizontalsurface
和 立法
作为对象属性
JSON 到 Typescript 接口(interface)
我使用了 JSON to TS Online Converter查看如何将 JSON 转换为 Typescript 接口(interface),结果如下:
interface RootObject {
name: string;
url: string;
type: string;
properties: Property3[];
}
interface Property3 {
name: string;
url: string;
type: string;
objPropSource?: string;
properties?: Property2[];
}
interface Property2 {
name: string;
url: string;
type: string;
objPropSource?: string;
properties?: Property[];
}
interface Property {
name: string;
url: string;
type: string;
}
推理
我推断使用来自递归 JSON 的接口(interface)的方法是不可扩展的,因为这样的产品本体可以扩展到 1000 个属性和属性中的属性。如上面提到的示例所示,对于父属性中的每个属性,将继续创建接口(interface)。
期待
我应该期望使用具有这种 JSON 结构的 Typescript 接口(interface),还是应该坚持创建一个类,然后遵循创建二叉树的传统方法,即。
export class leaf {
name: string;
url: string;
type: string;
children: leaf[] = [];
}
然后写一个递归直到解析完整的结构?
长话短说
Can Typescript interfaces be used for Large Recursive JSON Structures?
最佳答案
您应该能够将该结构很好地表示为递归接口(interface):
interface Property {
name: string;
url: string;
type: string;
objPropSource?: string;
properties?: Property[];
}
您尝试使用的 JSON 到 TS 转换器似乎没有识别结构递归性质的功能。
工作示例:
interface Property {
name: string;
url: string;
type: string;
objPropSource?: string; // optional property
properties?: Property[];
};
var p: Property = JSON.parse(getJson());
alert(p.properties[2].properties[0].name);
alert(p.properties[3].objPropSource);
function getJson() {
return `{
"name": "chair",
"url": "http://namespace.org#chair",
"type": "main",
"properties": [
{
"name": "height",
"url": "http://namespace.org#height",
"type": "dataprop"
},
{
"name": "width",
"url": "http://namespace.org#width",
"type": "dataprop"
},
{
"name": "horizontalsurface",
"url": "http://namespace.org#horizontalsurface",
"type": "objprop",
"objPropSource": "http://namespace.org#hasHorizontalSurface",
"properties": [
{
"name": "Legislation",
"url": "http://namespace.org#legislation",
"type": "objprop",
"objPropSource": "http://namespace.org#compliesWithLegislation",
"properties": [
{
"name": "hasLegislationName",
"url": "http://namespace.org#hasLegislationName",
"type": "dataprop"
}
]
}
]
},
{
"name": "legislation",
"url": "http://namespace.org#legislation",
"type": "objprop",
"objPropSource": "http://namespace.org#compliesWithLegistion",
"properties": [
{
"name": "hasLegislationName",
"url": "http://namespace.org#hasLegislationName",
"type": "dataprop"
}
]
}
]
}`;
}
