用于不同Schema.org类型的多个JSON-LD脚本：为什么在使用Google SDTT进行测试时将它们合并为一种类型？

Question

[我有一篇文章包含汽车和视频的评论，并且我想使用JSON-LD实现以下Schema.org类型：Article，VideoObject和Review。

我为每种Schema.org类型创建了以下单独的片段：

（（1）条：

<script type="application/ld+json">
{ "@context": "https://schema.org", 
 "@type": "Article",
 "name": "TitleOfArticle",
  "headline": "TitleOfArticle",
 "description": "DescriptionOfArticle",
 "image": {
    "@type": "ImageObject",
    "url": "https://www.example.com/imageofcarinarticle.png",
    "width": 1200,
    "height": 800
  },
  "author": {
    "@type": "Person",
    "name": "John Smith"
  },
"wordcount": "628",
"publisher": {
    "@type": "Organization",
    "name": "MyCompany",
    "logo": {
      "@type": "ImageObject",
      "url": "https://www.example.com/companylogo.png"
    }
  },
 "url": "https://www.example.com/articleurl",
   "mainEntityOfPage": {
    "@type": "WebPage",
    "@id": "https://www.example.com/articleurl"
  },
  "datePublished": "2019-09-16T11:30:19",  
  "dateCreated": "2019-09-16T11:30:19",
  "dateModified": "2019-09-16T11:30:19",
  "thumbnailUrl": "https://www.example.com/imageofcar.png"
 }
</script>

2）VideoObject

<script type="application/ld+json">
    {
      "@context": "https://schema.org/",
      "@type": "VideoObject",
      "name": "TitleOfArticle",
      "@id": "https://www.example.com/articleurl",
      "datePublished": "2019-09-16T11:30:19",
      "uploadDate": "2019-09-16T11:30:19",
      "duration": "PT5M33S",
      "description" : "DescriptionOfArticle",
      "thumbnailURL" : "https://www.example.com/thumbnailurl.png",
      "thumbnail" : "https://www.example.com/thumbnailurl.png",
      "contentUrl": "https://www.example.com/videourl.mp4",
      "author": {
        "@type": "Person",
        "name": "John Smith"
      }
    } 
</script>

3）评论

<script type='application/ld+json'>
{
  "@context": "https://schema.org/",
  "@type": "Review",
  "itemReviewed": {
    "@type": "Car",
    "name": "Mini Countryman",
    "model": "Countryman",
    "manufacturer": "Mini",
    "bodyType": "hatchback",
    "vehicleModelDate": "2019"
  },
  "author": {
    "@type": "Person",
    "name": "John Smith"
  },
  "image": {
    "@type": "ImageObject",
    "url": "https://www.example.com/imageofcarinarticle.png",
    "width": 1200,
    "height": 800
  },
  "publisher": {
   "@type": "Organization",
    "name": "MyCompany",
    "logo": {
      "@type": "ImageObject",
      "url": "https://www.example.com/companylogo.png"
    }
  },
  "@id": "https://www.example.com/articleurl",
  "headline": "TitleOfArticle",
 "description": "DescriptionOfArticle",
  "datePublished": "2019-09-16T11:30:19",
  "dateModified": "2019-09-16T11:30:19",
  "reviewBody": "ReviewOfCar",
  "reviewRating": {
    "@type": "Rating",
    "ratingValue": "6.0",
    "bestRating": "10"
  }
}
</script>

[当我分别使用Google结构化数据测试工具测试每个脚本时，一切都很好，没有错误。

如果我在同一页面中测试所有脚本，我仍然没有错误，但是所有类型都'合并为一种类型，Article，如下图所示。

正确吗？

[我似乎记得在过去使用Microdata而不是JSON-LD时有Article，VideoObject和Review分别的类型。

Answer 1

[@id]唯一地标识一个事物，因此，如果两个事物具有相同的@id值，则它们are相同。

您的WebPage，VideoObject和Review具有相同的@id值：

"@id": "https://www.example.com/articleurl"

如果您要提供@id（这是一种很好的做法），则它们都应具有不同的值，除非它们确实相同。
