I have a product reviews on a site and I am adding Schema.org markup to the reviews. Here is the code I am using:

<div class="blockquote-wrap">
 <blockquote itemprop="review" itemscope itemtype="http://schema.org/Review"><span itemprop="reviewBody">Text of the review itself.</span>
<cite><span itemprop="author">Author Name</span>, Location of Author</cite>

This is all the reviews are. When I test the page using Google's Structured Data Testing Tool I receive this error:

Error: Incomplete microdata with schema.org.

My question is what data is missing that is required? I don't see which data is required on the Schema.org page for reviews.

Needs to wrapped in /product or something appropriate. – closetnoc May 26 '14 at 21:57
As closetnoc commented, you'll need to nest the review under Product: <div itemscope itemtype="http://schema.org/Product"> and include a name (from the "Microdata" tab under "Examples" in the link you provided): <span itemprop="name">Kenmore White 17" Microwave</span>. That should remove the errors, as can be seen here. – dan May 27 '14 at 6:05
@dan - Will give it a try. Thank You. – L84 May 28 '14 at 5:35

Because microdata is structured, Review must be contained by an object or reference to an object being reviewed, or as the result (associated with an agent) of a ReviewAction. According to the documentation at http://schema.org/Review, instances of Review may appear as values for the following properties:

  • resultReview
  • Organization
  • Product
  • CreativeWork
  • Place
  • Offer
