The nameattribute is the "usual" way for specifying metadata in HTML. It's defined in the HTML5 spec.
该name属性是在 HTML 中指定元数据的“通常”方式。它在 HTML5 规范中定义。
The propertyattribute comes from RDFa.
该property属性来自RDFa。
RDFa 1.1 extends HTML5 so that it's valid to use metaand linkelements in the body, as long as they contain a propertyattribute.
RDFa 1.1 扩展了 HTML5，因此只要它们包含属性，就可以使用meta和 中的link元素bodyproperty。
You can use both ways, HTML5's nameand RDFa's property, together on the same metaelement.
您可以使用两种方式，HTML5的name和RDFa的property，一起上相同meta元素。
Note that you might also see metaelements with an itempropattribute. That would be from Microdata.
请注意，您可能还会看到meta带有itemprop属性的元素。那将来自Microdata。
