假设我有一个关于一个人找工作的简单HTML页面：

<!DOCTYPE HTML>
<html>
    <head>
        <meta charset="utf-8">
        <title>New Job for John Doe</title>
    </head>
    <body>
        <h1>New Job for John Doe</h1>
        <p>This week John Doe accepted an offer to become a Software Engineer at MITRE.  John graduated from MIT in 2005 with a BS in Computer Science.  He previously worked at a small company near Boston.  Blah, blah, blah.</p>
        <p>The MITRE Corporation is a not-for-profit organization chartered to work in the public interest.  The MITRE Corporation has two principal locations: Bedford, Massachusetts, and McLean, Virginia.  Blah, blah, blah.</p>
    </body>
</html>

如果我使用schema.org词汇表添加语义数据，它可能如下所示：

<!DOCTYPE HTML>
<html>
    <head>
        <meta charset="utf-8">
        <title>New Job for John Doe</title>
    </head>
    <body>
        <h1>New Job for John Doe</h1>
        <p itemscope itemtype="http://schema.org/Person">This week John Doe accepted an offer to become a <span itemprop="jobTitle">Software Engineer</span> at <span itemprop="worksFor">MITRE</span>.  John graduated from <span itemprop="alumniOf">MIT</span> in 2005 with a BS in Computer Science.  He previously worked at a small company near Boston.  Blah, blah, blah.</p>
        <p itemscope itemtype="http://schema.org/Corporation">The MITRE Corporation is a not-for-profit organization chartered to work in the public interest.  The MITRE Corporation has two principal locations: <span itemprop="location">Bedford, Massachusetts</span>, and <span itemprop="location">McLean, Virginia</span>.  Blah, blah, blah.</p>
    </body>
</html>

第一段显然是关于无名氏，第二段是关于一家公司，MITRE公司。但第一段中的" MITRE“与第二段中的”MITRE Corporation“是相同的。我如何使用schema.org显式地声明它们是一个相同的东西？

我第一次尝试回答自己的问题是使用itemref属性，如下所示：

<p itemscope itemtype="http://schema.org/Person">
    This week John Doe accepted an offer to become a
    <span itemprop="jobTitle">Software Engineer</span>
    at <span itemprop="worksFor" itemref="TheMitreCorporation">MITRE</span>.
    John graduated from <span itemprop="alumniOf">MIT</span>
    in 2005 with a BS in Computer Science.
    He previously worked at a small company near Boston.  Blah, blah, blah.
</p>

<p itemscope itemtype="http://schema.org/Corporation" id="TheMitreCorporation">
    The MITRE Corporation is a not-for-profit organization chartered to work in the public interest.
    The MITRE Corporation has two principal locations:
    <span itemprop="location" itemscope itemtype="http://schema.org/Place">
        <span itemprop="name">Bedford, Massachusetts</span>
    </span>, and
    <span itemprop="location" itemscope itemtype="http://schema.org/Place">
        <span itemprop="name">McLean, Virginia</span>
    </span>. Blah, blah, blah.
</p>

但一些评论者正确地指出，这不是对该属性的正确使用。

因此，这是我的第二个尝试:使用itemid属性。公司名称的两个实例都被赋予了itemscope和itemtype属性，并且它们都被设置为相同的URL值，这是一个itemid。

spec says：“如果指定了itemid属性，它的值必须是可能包含在item中的有效URL值。item的全局标识符是其元素的itemid属性的值，如果有，则相对于该属性为specified...The的元素进行解析。不能在没有同时指定itemscope属性和itemtype属性的元素上指定itemid属性。”

<p itemscope itemtype="http://schema.org/Person">This week John Doe accepted an offer to become a <span itemprop="jobTitle">Software Engineer</span> at <span itemprop="worksFor" itemscope itemtype="http://schema.org/Corporation" itemid="http://www.mitre.org">MITRE</span>.  John graduated from <span itemprop="alumniOf">MIT</span> in 2005 with a BS in Computer Science.  He previously worked at a small company near Boston.  Blah, blah, blah.</p>
<p itemscope itemtype="http://schema.org/Corporation" itemid="http://www.mitre.org">The MITRE Corporation is a not-for-profit organization chartered to work in the public interest.  The MITRE Corporation has two principal locations: <span itemprop="location" itemscope itemtype="http://schema.org/Place"><span itemprop="name">Bedford, Massachusetts</span></span>, and <span itemprop="location" itemscope itemtype="http://schema.org/Place"><span itemprop="name">McLean, Virginia</span></span>.  Blah, blah, blah.</p>

//更新: Schema.org扩展了他们的perso模式规范

很明显，人与公司有关，所以你能做的就是在人和组织之间建立一个具有“Person‘s”项属性“从属关系”的关系，所以我所做的就是用项范围itemtype=" person“包装段落，并通过添加项属性”从属关系“和项范围itemtype=" organization”来扩展Schema Person，所以现在有了一个语义关系，个人与组织有关系。我还添加了带有itemprop="name“的meta标签，因为它需要满足"Person”规范。

<!DOCTYPE HTML>
<html>
<head>
    <meta charset="utf-8">
    <title>New Job for John Doe</title>
</head>
<body>
<div itemscope itemtype="http://schema.org/Person">
    <h1>New Job for John Doe</h1>
<meta itemprop="name" content="John Doe" />
    <p>This week John Doe accepted an offer to become a <span itemprop="jobTitle">Software Engineer</span> at <span itemprop="worksFor">MITRE</span>.  John graduated from <span itemprop="alumniOf">MIT</span> in 2005 with a BS in Computer Science.  He previously worked at a small company near Boston.  Blah, blah, blah.</p>
    <p itemprop="affiliation" itemscope itemtype="http://schema.org/Organization">The MITRE Corporation is a not-for-profit organization chartered to work in the public interest.  The MITRE Corporation has two principal locations: <span itemprop="location">Bedford, Massachusetts</span>, and <span itemprop="location">McLean, Virginia</span>.  Blah, blah, blah.</p>
</div> <!-- closing Schema "Person" -->
</body>
</html>

你可以把它放到谷歌丰富的代码片段测试工具中，我猜输出就是你想要的

Item 
type:   http://schema.org/person
property:   
name:   John Doe
jobtitle:   Software Engineer
worksfor:   MITRE
alumniof:   MIT
affiliation: Item 1


Item 1
type:   http://schema.org/organization
property:   
location:   Bedford, Massachusetts
location:   McLean, Virginia
