问题描述
试图在语义上标记有关特定地址的报告页面.该页面提供有关地址能耗的报告，并提供与能耗有关的服务的报价.我想在语义上表示该地点的地址，与该地址有关的能源报告以及该地址可用的报价.现在，我有一个标记，其中有一个RDFa lite节点用于放置，另一个节点用于商品.构造此关系以在这些事物之间建立关系的最佳方法是什么，例如，该地点的能源报告和相关报价?
trying to semantically mark up a report page about specific addresses. The page provides a report about the address's energy consumption and presents offers for a service related to the energy consumption. I would like to semantically represent the place's address, the energy report related to the address, and offers that are available to the address. Right now, I have markup that has an RDFa lite node for place and another node for the offers. What is the best way to structure this to establish a relationship between these things, e.g., energy report and related offers for this place?

推荐答案
<div vocab="http://schema.org/" typeof="Place" additionaltype="Offer" resource="#energyreport">
首先，additionaltype属性在HTML中无效，因此不应使用.使用RDFa，您可以安全地在typeof属性中放置多种类型，例如:typeof="Place Offer".
First of all, the additionaltype attribute is not valid in HTML and should not be used. With RDFa, you can safely put multiple types in the typeof attribute, like this: typeof="Place Offer".
要补充约书亚所说的话(很棒)，如果您不想添加可见链接，也可以使用不可见的<link>元素:
To complement what Joshua said (which is great), if you don't want to add a visible link, you can also use an invisible <link> element:
<link property="offer" href="#offer" />
另一个检查您的RDFa的是 RDFa/播放.可从 RDFa.info的工具中获得更多工具.
Another to check your RDFa is RDFa / Play. More tools are available from RDFa.info's Tools.
