The Schema.org markup can help search engines and other crawlers understand better what your site and content is about. The <a href="https://wordpress.org/plugins/wordpress-seo/" rel="ugc">Yoast SEO</a> plugin does an amazing job of generating that markup.
But sometimes the markup generated by the Yoast plugin is not enough. There are some niche structures, that would not make sense to be implemented in a big plugin, as most of the users would not use those features. Any may be confused by their existence.
This is why this plugin exists. In this plugin we can add fun, useful and experimental Schema.org markup, that better describes what content is available on the site and what that content is about.
<h4>Current Extensions</h4>
Spouse 
You can select another WordPress user in a user profile that is then marked as a <a href="https://schema.org/spouse" rel="nofollow ugc">spouse</a> of that user. Be advised, this connection is not bidirectional.
Honorific Titles 
You can set a honorific <a href="https://schema.org/honorificPrefix" rel="nofollow ugc">prefix</a> and <a href="https://schema.org/honorificSuffix" rel="nofollow ugc">suffix</a> for a specific user.
<h4>Make this better</h4>
