I have a site that has many articles on a specific dog breed. I want to help Google and other search engines to understand this article is specifcally on this breed or a topic realted to this breed. I thought about using productontology.org to define an additional type.
For example I have the following Schema.org markup:
<article itemscope itemtype="http://schema.org/Article"> <link itemprop="additionalType" href="http://www.productontology.org/id/dog_breed" /> <!-- Additional Code + Schema.org markup --> </article>
Is this the correct way to indicate with Schema.org markup that this article is on (or related to) this specific breed? If not, what is the proper way using Schema.org?
Note: I understand fully that the best way is with great content that uses keywords. However, I am looking to know how to do this from a schema.org perspective.
