Question

假设我有一个关于找工作的人的简单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>

第一段显然是关于这个人，John Doe，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公司”相同。如何使用schema.org明确声明这些是同一个？

Answer 1

//更新：Schema.org扩展了他们的perso schema规范

显然，这个人与公司有关系，所以你能做的就是在人与组织之间建立一种“人”的关系“从属关系” 所以我所做的是用itemscope itemtype =“Person”包装段落，并通过添加itemprop“affiliation”和itemscope itemtype =“Organization”扩展Schema Person，所以现在有一个语义关系，这个人与组织有关系。我还添加了带有itemprop =“name”的元标记，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片段测试工具中，我猜输出就是你在哪里寻找

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

Answer 2

我第一次尝试回答我自己的问题是使用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>

但是一些评论者正确地指出这不是这个属性的正确用法。

所以这是我的第二次尝试：改为使用itemid属性。公司名称的两个实例都具有itemscope和itemtype属性，并且它们都设置为相同的itemid值，即URL。

spec says：“itemid属性（如果已指定）必须具有可能由空格包围的有效URL的值...项目的全局标识符是其元素的itemid属性的值，如果它有一个，相对于指定属性的元素进行解析...不能在没有指定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>

如何关联schema.org中的项目？
