Question

如果我使用 <div>标签 itemprop="review"项目范围 itemtype="http://mydomainname.com/Review" itemtype 那么我是否需要在我的网站上创建一个名为 review 的页面？

Answer 1

我建议您阅读 this tutorial在 HTML5 微数据上。这是关于 itemtype 的文档的摘录:

The itemscope attribute us used to indicate that the element it is placed on and it’s children represent a microdata item. The itemscope should be paired with an itemtype attribute that defines the microdata vocabulary in use.

<p itemscope itemtype="http://www.data-vocabulary.org/Organization/"> ...

Additional data ...

Microdata vocabularies can be nested and can be dependent on one another. For example, the organization microdata vocabulary also contains an address as a member. The itemtype url can point to anything. Think of it as just a unique character string that various programs have agreed that when they see that specific ID, they know how to parse and look for the itemprop tags in the sub-elements to extract the meaning needed from the document.

有预定义的itemtype值，或者您可以创建自己的值。它们可以是 URL，但不一定是。
