为何我的Schema服务未被正确识别？请求验证定价表Microdata

我不确定我的定价表是否已按照Schema/Microdata规范正确配置，能否协助验证？Schema官方验证工具未检测到任何错误或警告，但在验证过程中，由于使用了PriceSpecification和minPrice，‘Hair colour’服务未被正确识别为Service类型。

原代码如下：

<table>
  <thead>
    <tr>
      <th scope="col">Treatment</th>
      <th scope="col">Price</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th colspan="2" scope="col">Cuts and hair colours</th>
    </tr>
    <tr itemscope itemtype="https://schema.org/Service">
      <td itemprop="name">Consultation<br /> <small>when you need ideas</small></td>
      <td itemprop="offers" itemscope itemtype="https://schema.org/Offer">
        <span itemprop="price" content="0">Free</span>
        <meta itemprop="priceCurrency" content="DKK" />
      </td>
    </tr>
    <tr itemscope itemtype="https://schema.org/Service">
      <td itemprop="name">Lady haircut<br /> <small>including wash</small></td>
      <td itemprop="offers" itemscope itemtype="https://schema.org/Offer">
        <span itemprop="price" content="660">660</span>
        <span itemprop="priceCurrency" content="DKK">kr.</span>
      </td>
    </tr>
    <tr itemscope itemtype="https://schema.org/Service">
      <td itemprop="name">Hair colour<br /> <small>including wash</small></td>
      <td itemprop="offers" itemscope itemtype="https://schema.org/Offer">
        <div itemscope itemtype="https://schema.org/PriceSpecification">
          <span itemprop="minPrice" content="1650">from 1.650</span>
          <span itemprop="priceCurrency" content="DKK">kr.</span>
        </div>
      </td>
    </tr>
  </tbody>
</table>

问题原因 #

问题出在Offer与PriceSpecification的关联逻辑上。按照Schema规范，Offer需要通过priceSpecification属性来关联PriceSpecification对象，原代码中仅嵌套了PriceSpecification但未指定该 itemprop，导致两者的关联关系未被验证工具识别，进而影响了上层Service类型的判定。

修正后的代码 #

<table>
  <thead>
    <tr>
      <th scope="col">Treatment</th>
      <th scope="col">Price</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th colspan="2" scope="col">Cuts and hair colours</th>
    </tr>
    <tr itemscope itemtype="https://schema.org/Service">
      <td itemprop="name">Consultation<br /> <small>when you need ideas</small></td>
      <td itemprop="offers" itemscope itemtype="https://schema.org/Offer">
        <span itemprop="price" content="0">Free</span>
        <meta itemprop="priceCurrency" content="DKK" />
      </td>
    </tr>
    <tr itemscope itemtype="https://schema.org/Service">
      <td itemprop="name">Lady haircut<br /> <small>including wash</small></td>
      <td itemprop="offers" itemscope itemtype="https://schema.org/Offer">
        <span itemprop="price" content="660">660</span>
        <meta itemprop="priceCurrency" content="DKK" />
        <span>kr.</span>
      </td>
    </tr>
    <tr itemscope itemtype="https://schema.org/Service">
      <td itemprop="name">Hair colour<br /> <small>including wash</small></td>
      <td itemprop="offers" itemscope itemtype="https://schema.org/Offer">
        <div itemprop="priceSpecification" itemscope itemtype="https://schema.org/PriceSpecification">
          <span itemprop="minPrice" content="1650">from 1.650</span>
          <meta itemprop="priceCurrency" content="DKK" />
          <span>kr.</span>
        </div>
      </td>
    </tr>
  </tbody>
</table>

修正说明 #

1. 在PriceSpecification的外层div添加itemprop="priceSpecification"，明确它是Offer的属性，建立起两者的关联关系，让验证工具能正确识别Service结构
2. 将所有priceCurrency的展示与Schema内容分离：用meta标签存储规范的货币代码（DKK），页面显示的"kr."单独用span标签，避免内容混淆，同时符合Schema规范

这样修改后，验证工具就能正确识别‘Hair colour’对应的Service类型，且无规范错误。
