Schema output for News SEO for WordPress

The schema output for News SEO for WordPress builds upon Yoast SEO for WordPress' base schema output, to provide additional news context and detail.

Core logic

When a post type has been elected as a News Article format, then:

• Change the the @type attribute of the Article to a NewsArticle.
• Add a copyrightYear property, with the year of publication.
• Add a copyrightHolder property, which references the publishing Organization by ID.

Additional scenarios

On pages which don't have an Article

In some rare cases, a non-post format (e.g., a page, a custom post type, a homepage, a product page, etc) may be elected as a news type. Typically, these page formats won't contain an Article. In these cases, an Article (and dependent pieces) should be added to the graph and upgraded to a NewsArticle, as if the page were a conventional news post. In the case that this results in multiple entities declaring a mainEntityOfPage relationship with the WebPage (e.g., when the page already contains a Product), then the mainEntityOfPage property on the conflicting node(s) (e.g., the Product ) should be altered to reference the ID of the NewsArticle.
