作为博客发布一部分的图像/徽标的微数据错误

我在使用 Google 结构化数据测试工具获取发布商徽标和博客文章图像进行验证时遇到问题。

我目前拥有的一些示例标记是：

 <article class="post" itemscope itemprop="blogPost" itemtype="http://schema.org/BlogPosting">
     <div class="preview">
         <h2 itemprop="mainEntityOfPage headline"><a href="/blog/improving-the-patient-experience-through-the-revenue-cycle-part-1">Improving the Patient Experience through the Revenue Cycle Part 1</a></h2>
         <div class="meta">
         <span itemprop="datePublished" class="published-date">Friday, February 19, 2016</span>
         <span class="sep">|</span>
         <span itemprop="author" class="author"><a title="Posts by Laurie Shoaf" href="/blog/?author=Laurie+Shoaf">Laurie Shoaf</a></span>
         <span class="sep">|</span>
         <span class="category"><a title="Posts in Revenue Cycle Management" href="/blog/?category=Revenue+Cycle+Management">Revenue Cycle Management</a></span>
         <span class="sep">|</span>
         <span class="comments"><a title="Improving the Patient Experience through the Revenue Cycle Part 1 Comments" href="/blog/improving-the-patient-experience-through-the-revenue-cycle-part-1#comments">Comments<span class="hide" itemprop="discussionUrl">/blog/improving-the-patient-experience-through-the-revenue-cycle-part-1#comments</span></a></span>
         </div>
         <p itemprop="description" class="snippet">This three part series will focus on strategies to augment revenue cycle operations in order to improve the patient experience.

         <span class="hide" itemscope="" itemprop="publisher" itemtype="http://schema.org/Organization"><span itemprop="name">CCi</span><img itemprop="logo" src="/media/cci-small.png" alt="CCi Logo" title="CCi | Power on the Inside" /></span>
         <span class="hide" itemprop="dateModified">2/19/2016</span>
         <img itemprop="image" src="/media/blog featured/blog-post.png" class="hide" alt="Blog Post Graphic" title="Improving the Patient Experience through the Revenue Cycle Part 1" />
     </div>
    </article>

我在测试端收到的错误是：

• 发布者 -> 徽标：属性 itemtype 具有无效值。
• 图像：图像字段的值是必需的。

将这些属性嵌套在“blogPost”架构中以通过验证的正确方法是什么？

在这两种情况下，谷歌都希望看到ImageObject项目（用于显示他们的文章丰富片段).

<div itemprop="logo" itemscope itemtype="http://schema.org/ImageObject">
  <!-- … -->
</div>

<div itemprop="image" itemscope itemtype="http://schema.org/ImageObject">
  <!-- … -->
</div>
