¿Usando Schema.org Review con copyrightHolder?

When reviewing a video game, there are dos CreativeWorks (resp. more specific types) involved:

• el videojuego
• La revisión

Las propiedades copyrightYear y copyrightHolder refer to the nearest parent CreativeWork. You have to make sure not to mix them: it’s all about the correct nesting.

<div itemscope itemtype="http://schema.org/CreativeWork">
  <!-- this is *your* CreativeWork, i.e., the review -->
  <div itemprop="itemReviewed" itemscope itemtype="http://schema.org/CreativeWork">
    <!-- this is *not your* CreativeWork, i.e., the video game -->
  </div>
  <!-- this is, again, *your* CreativeWork -->
</div>

(Note that I’ve used the general CreativeWork type in this example; you should of course use more specific types if available, e.g., http://schema.org/Review for the review).

Daniel, you should use the review schema as your primary schema, then nest the others such as creative work within it. The review schema should include the item, the author's name, date of the review, and of course the actual review body and rating markups. But it really is not necessary to use the copyright item properties. You can simply leave those tags out if you wish.
