你如何结合几个JSON-LD标记？ [英] How do you combine several JSON-LD markups?

问题描述

我发现很难将几个或几个JSON-LD标记合并为一个新手。您能告诉我我做错了什么吗？

当我在Google结构化数据测试工具中输入以下标记时，它只显示组织模式类型，同时还有 BreadcrumbList 类型。

 < script type =application / ld + json> 
 {
@context：http://schema.org，
@type：Organization，
legalName：示例INC， 
logo：https://www.example.com/image.png，
url：https://www.example.com/，
 sameAs：[
https://www.facebook.com/example，
https://www.linkedin.com/company/example，
https：/ /twitter.com/example，
https://www.youtube.com/user/example，
https://en.wikipedia.org/wiki/example
] 
} 
@type：BreadcrumbList，
itemListElement：[
 {
@type：ListItem，
position：1，
item：{
@id：https://www.example.com/，
name：Homepage 
} 
} 
] 
< / script> 
  

解决方案

为了指定多个顶级项目，选项：
$ b

Array

 < ; script type =application / ld + json> 
 [
 {
@context：http://schema.org，
@type：组织
}，
 {
@context：http://schema.org，
@type：BreadcrumbList
} 
] 
   

缺点：您必须重复 @context 为每个项目。

@graph

 < script type =application / ld + json> 
 {
@context：http://schema.org，
@graph：
 [
 {
@type ：组织
}，
 {
@type：BreadcrumbList
} 
] 
} 
   

多个脚本元素

 < script type =application / ld + json> 
 {
@context：http://schema.org，
@type：Organization
} 
< / script> 
 
< script type =application / ld + json> 
 {
@context：http://schema.org，
@type：BreadcrumbList
} 
< / script> 
  

缺点：您必须重复脚本元素和 @context 为每个项目。

但它通常最好只提供一个顶层项目，并将其他项目嵌套在适当的属性下。尽管如此，这在所有情况下都是不可能的。

在你的情况下，通过添加一个 WebPage 项似乎是可能的，假设它是组织的页面，有这样的面包屑列表：

 < script type =application / ld + json> 
@context：http://schema.org，
@type：WebPage，
provider：
 { 
@type：Organization
}，
breadcrumb：
 {
@type：BreadcrumbList
} 
} 
< / script> 
  

（您可以在不嵌套的情况下实现相同的功能：为每个项目指定一个包含 @id 的URI，然后将这些URI作为属性值引用。）

I'm finding it difficult to merge couple or several JSON-LD markups together being a novice. Could you please tell me what I'm doing wrong?

When I enter the following markup into Google Structured Data Testing Tool, it only shows results for the Organization schema type while there's BreadcrumbList type too.

<script type="application/ld+json">
{
"@context": "http://schema.org",
"@type": "Organization",
"legalName": "Example INC",
"logo": "https://www.example.com/image.png",
"url": "https://www.example.com/",
"sameAs": [
"https://www.facebook.com/example",
"https://www.linkedin.com/company/example",
"https://twitter.com/example",
"https://www.youtube.com/user/example",
"https://en.wikipedia.org/wiki/example"
]
}
"@type": "BreadcrumbList",
"itemListElement": [
{
"@type": "ListItem",
"position": "1",
"item": {
"@id": "https://www.example.com/",
"name": "Homepage" 
}
}
]
</script>

解决方案

For specifying multiple top-level items, you have three options:

Array

<script type="application/ld+json">
[
  {
     "@context": "http://schema.org",
     "@type": "Organization"
  },
  {
     "@context": "http://schema.org",
     "@type": "BreadcrumbList"
  }
]
</script>

Drawback: You have to repeat the @context for each item.

@graph

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@graph": 
  [
    {
       "@type": "Organization"
    },
    {
       "@type": "BreadcrumbList"
    }
  ]
}
</script>

Multiple script elements

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "Organization"
}
</script>

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "BreadcrumbList"
}
</script>

Drawback: You have to repeat the script element and the @context for each item.

But it’s typically preferable to provide only one top-level item, and nest the additional items under suitable properties. This is not possible in all cases, though.

In your case it seems to be possible by adding a WebPage item, assuming it’s the organization’s page and this page has this breadcrumb list:

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "WebPage",
  "provider": 
  {
    "@type": "Organization"
  },
  "breadcrumb": 
  {
    "@type": "BreadcrumbList"
  }
}
</script>

(You can achieve the same without nesting: give each item a URI with @id, and then reference these URIs as property values.)
