我想在我的网站中集成JSON-LD。目前我使用Microdata进行语义标记：
<!DOCTYPE html>
<html itemscope itemtype="http://schema.org/WebSite">
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<meta charset="UTF-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
<title itemprop="name">Semantic Markup Sample</title>
<meta name="description" itemprop="description" content="Demonstrate some sample semantic markup."/>
<meta name="keywords" content="HTML, Semantic, Microdata, JSON-LD"/>
<meta name="author" content="burnersk"/>
<meta itemprop="datePublished" content="2017-10-12T09:48:17+02:00">
<meta name="date" itemprop="dateModified" content="2017-10-12T09:51:03+02:00"/>
<link rel="canonical" itemprop="url" href="https://example.com/semantic-markup-sample.html"/>
</head>
<body>
<header>

现在我想在Microdata旁边添加JSON-LD标记以进行测试运行。
然而，对于嵌套的JSON-LD标记来说，这是一种挑战。我找不到嵌套JSON-LD的资源。我没有看到JSON-LD的范围功能来指示HTML的哪些部分被描述（比如itemscope和Microdata。）
我的示例网站（见上面的代码）分为3个部分：
WebSite包含的对象
Article对象“第二条”和Article对象“第一条”。如何为这样的嵌套网站实施JSON-LD？
答案 0 :(得分：2)
Microdata 没有描述HTML部分，它只是使用 HTML作为传输媒介。因此，在提取微数据之后，任何与HTML的连接都将丢失。
以下代码段在语义上不同（HTML），但产生相同的微数据：
<div itemscope itemtype="http://schema.org/WebPage">
<p itemprop="name">Hello world</p>
</div>
<div itemscope itemtype="http://schema.org/WebPage">
<p itemprop="name">Hello <b>world</b></p>
</div>
<div itemscope itemtype="http://schema.org/WebPage">
<strong itemprop="name">Hello world</strong>
</div>
<h1>Hello world</h1>
<div itemscope itemtype="http://schema.org/WebPage">
<meta itemprop="name" content="Hello world" />
</div>
JSON-LD 的工作方式与上一个Microdata示例类似：现有HTML的数据gets specified independently：
<h1>Hello world</h1>
<script type="application/ld+json">
{
"@context": "http://schema.org",
"@type": "WebPage",
"name": "Hello world"
}
</script>
在您的Microdata示例中，您指定了三个顶级项目。要在JSON-LD中执行此操作，您可以使用multiple script elements（每个项目一个）或使用一个script元素with @graph，例如：
<script type="application/ld+json">
{
"@context": "http://schema.org",
"@graph":
[
{
"@type": "WebPage"
},
{
"@type": "Article"
},
{
"@type": "Article"
}
]
}
</script>
（请注意，如果可能的话，最好连接具有合适属性的项目。在典型情况下，您将只有一个顶级项目引用/嵌套其他项目。）
