Question

我正在研究JSON-LD，特别是与schema.org结合使用。

schema.org/Person的一个Json-LD示例让我觉得错误：

        {
          "@context": "http://schema.org",
          "@type": "Person",
          "address": {
            "@type": "PostalAddress",
            "addressLocality": "Seattle",
            "addressRegion": "WA",
            "postalCode": "98052",
            "streetAddress": "20341 Whitworth Institute 405 N. Whitworth"
          },
          "colleague": [
            "http://www.xyz.edu/students/alicejones.html",
            "http://www.xyz.edu/students/bobsmith.html"
          ],
          "email": "mailto:jane-doe@xyz.edu",
          "image": "janedoe.jpg",
          "jobTitle": "Professor",
          "name": "Jane Doe",
          "telephone": "(425) 123-4567",
          "url": "http://www.janedoe.com"
        }

我觉得错误的是colleague被定义为type = Person（参见上面的链接），而是提供了实体引用（url / text）。

格式化的正确方法似乎是在@context中提供额外信息，如下所示：

        {
          "@context": {
                "@vocab": "http://schema.org/",
                "colleague": { "@type": "@id" }
            },
          "@type": "Person",
          "address": {
            "@type": "PostalAddress",
            "addressLocality": "Seattle",
            "addressRegion": "WA",
            "postalCode": "98052",
            "streetAddress": "20341 Whitworth Institute 405 N. Whitworth"
          },
          "colleague": [
            "http://www.xyz.edu/students/alicejones.html",
            "http://www.xyz.edu/students/bobsmith.html"
          ],
          "email": "mailto:jane-doe@xyz.edu",
          "image": "janedoe.jpg",
          "jobTitle": "Professor",
          "name": "Jane Doe",
          "telephone": "(425) 123-4567",
          "url": "http://www.janedoe.com"
        }

schema.org（代码示例1）上的示例是否确实不正确/不完整，代码示例2是否正确？

或者一般来说：当引用而不是嵌入实体时，是否需要将其显式化（使用@type: @id），或者，在规范中是否存在一些隐含的概念，即当值是URL时它被认为是是@id的参考？

你是对的，这个例子不是100％正确。缺少对@id的类型强制。我提交了一个错误来解决这个问题：https://github.com/schemaorg/schemaorg/issues/929

do type = @ id值必须在JSON-LD中显式输入吗？
