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源消耗的报告，并提供与能源消耗相关的服务。我想在语义上表示该地点的地址、与该地址相关的能源报告以及该地址可用的优惠。现在，我有一个标记，其中有一个 RDFa 精简版节点用于地点，另一个节点用于报价。构建此结构以在这些事物之间建立关系的最佳方式是什么，例如能源报告和该地点的相关报价？

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，不应使用。使用 RDFa，您可以安全地将多个类型放入 typeof属性，像这样:typeof="Place Offer" .
为了补充 Joshua 所说的(这很棒)，如果您不想添加可见链接，您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 .更多工具可从 RDFa.info's Tools 获得.
