jsonld for CWEType

对于CWEType实体的jsonld视图可通过显式方式或通过BASE_URL/.jsonld URL访问。它使用jsonld规范提供模式信息。

假设你有以下模式声明

class Person(EntityType):
    name = String()
    age = Int()
    birthdate = Date()

相应的jsonld输出将是

{
    "@context": {
        "xsd": "http://www.w3.org/2001/XMLSchema#",
        "creation_date": {
          "@id": "https://my-app.org/CWRType/creation_date",
          "@type": "xsd:dateTime"
        },
        "modification_date": {
          "@id": "https://my-app.org/CWRType/modification_date",
          "@type": "xsd:dateTime"
        },
        "cwuri": {
          "@id": "https://my-app.org/CWRType/cwuri",
          "@type": "@id"
        },
        "eid": {
          "@id": "https://my-app.org/CWRType/eid",
          "@type": "xsd:integer"
        },
        "name": {
          "@id": "https://my-app.org/CWAttribute/278",
          "@type": "xsd:string"
        },
        "age": {
          "@id": "https://my-app.org/CWAttribute/281",
          "@type": "xsd:string"
        },
        "birthdate": {
          "@id": "https://my-app.org/CWAttribute/301",
          "@type": "xsd:date"
        }
    }
}

jsonld for any rset

此视图与标准jsonexport视图有些相似，主要有两个不同点

• 它提供结果集元数据与实际数据一起，并尽可能接近sparql-results-json格式的总体形状，

• 每个单元格都作为一个“jsonld”对象公开。实体公开所有属性和dc属性，“最终”值公开其类型和值。

考虑RQL查询Any P,N LIMIT 2 WHERE P is Person, P name N，jsonld输出将如下所示

{
    "@context": {
        "cw": "http://ns.cubicweb.org/cubicweb/0.0/",
        "xsd": "http://www.w3.org/2001/XMLSchema#",
        "dcterms": "http://purl.org/dc/terms/",
        "myapp": "https://my-app.org/CWEType/"
    },
    "cw:head": {
        "rql": "Any P,N LIMIT 2 WHERE P is Person, P name N",
        "vars": ["P", "N"],
        "limit": 2
    },
    "cw:results": [
        [{
            "@context": "https://my-app.org/Person.jsonld",
            "@type": "myapp:Person",
            "cwuri": "https://my-app.org/1234",

            "dcterms:title": "the result of p.dc_title() on John",
            "dcterms:description": null
        },
        {
            "@type": "xsd:string",
            "@value": "John"
        }],
       [{
            "@context": "https://my-app.org/Person.jsonld",
            "@type": "myapp:Person",
            "cwuri": "https://my-app.org/4321",

            "eid": 4321,
            "dcterms:title": "the result of p.dc_title() on Mary",
            "dcterms:description": null
       },
        {
            "@type": "xsd:string",
            "@value": "Mary"
        }]
    ]
