schema.org:具有多个元素的SiteNavigationElement [英] schema.org: SiteNavigationElement with multiple elements

问题描述

我正在尝试为菜单导航实现schema.org微数据. 此导航将类似于以下内容:

I am trying to implement schema.org microdata for my menu navigation. This navigation will look similar to this:

<ul>
    <li><a href="#"><span>Name1</span></a></li>
    <li><a href="#"><span>Name2</span></a></li>
    <li><a href="#"><span>Name3</span></a></li>
</ul>

我想利用SiteNavigationElement，不幸的是，我只能在没有找到如何利用多个元素的明确答案的地方找到示例.

I want to make use of SiteNavigationElement, unfortunately all I could find where examples with no clear answer of how to make use of multiple elements.

有人肯定知道如何在多个元素上使用SiteNavigationElement吗?

Does anybody know for sure, how to use SiteNavigationElement on multiple elements?

更新:

这是我在阅读重复链接中的所有答案后想到的原始菜单结构:

This is my original menu structure I came up with after reading all answers in the duplicate link:

<nav class="menu" itemscope itemtype="http://schema.org/SiteNavigationElement">
    <ul class="main-menu" role="menubar">
        <li class="main-menu">Home</li>
        <li class="parent">
            <ul class="sub-menu">
                <li><a itemprop="url" role="menuitem" href="index.php"><span itemprop="name">Home</span></a></li>
                <li><a itemprop="url" role="menuitem" href="tricks.php"><span itemprop="name">Tricks</span></a></li>
                <li><a itemprop="url" role="menuitem" href="features.php"><span itemprop="name">Features</span></a></li>
            </ul>
        </li>
    </ul>
 </nav>

现在，所有内容都已被Google完全索引，我可以在 Google网站站长工具中看到它.

Now, everything has been fully indexed by google and I am able to see it in Google Webmaster Tools.

那么Google网站站长工具如何看到它?

Page URL   | Items | Items with errors | Last detected |    Name    | Errors
----------------------------------------------------------------------------
Page1.php  |   1   |          -        |     2/11/16   |  Features  |    -
Page2.php  |   1   |          -        |     2/11/16   |  Features  |    -
Page3.php  |   1   |          -        |     2/11/16   |  Features  |    -
Page4.php  |   1   |          -        |     2/11/16   |  Features  |    -
...

我所有已被索引并具有菜单(Page1.php-Page4.php)的页面，每个页面只有 1 个项目.并且检测到的项目始终只是 SiteNavigationElement 中指定的最后一个链接.

All my pages which have been indexed and have the menu (Page1.php - Page4.php), each only have 1 item. And the detected item is always only the last link specified in SiteNavigationElement.

因此显然必须有一个错误.

So there must be an error obviously.

• 为什么Google只看到一个链接?
• 为什么总是最后一个链接?

• Why is google only seeing one link?
• And why is it always the last link?

推荐答案

这是我阅读重复链接

除了我的答案，似乎;-)正如我在我对可能重复的问题的答案中所述，url属性应该不用于每个导航链接.相反，url属性应提供整个导航的URL(通常不存在).

Except my answer, it seems ;-) As I explained in my answer to the possibly duplicate question, the url property should not be used for each navigation link. Instead, the url property should provide a URL for the whole navigation (which, typically, doesn’t exist).

其他所有SiteNavigationElement属性也是如此(自Schema.org 版本2.2 )，例如您的示例中的name:它是用于导航的名称(例如，"Navigation")，而不是用于导航条目的名称.

The same goes for every other SiteNavigationElement property (as of Schema.org version 2.2), like name in your example: it’s for the name of the navigation (e.g., "Navigation"), not for the names of the navigation entries.

因此，使用 SiteNavigationElement 似乎不是很有用. WebPageElement 及其其他子类型也是如此.它们在特殊情况下和非HTML上下文中可能有用，但是通常我不会在典型的网页上使用它们

So using the SiteNavigationElement does not seem to be very useful. The same is the case with WebPageElement and its other sub-types. They may be useful in special cases and in non-HTML contexts, but generally I wouldn’t use them for typical Web pages.
