尝试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，该位置的能源报告和相关报价？

最佳答案
<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，可以安全地将多种类型放入typeof属性中，如下所示:typeof="Place Offer"。为了补充约书亚所说的(很好)，如果您不想添加可见链接，也可以使用不可见的
<link>元素:<link property="offer" href="#offer" />
另一个检查您的RDFa的是RDFa / Play。 RDFa.info's Tools提供了更多工具。
