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>

CherryPick Studios

A missing feature from Yoast SEO plugin. This is a very important SEO step to add your sitemap to the robots.txt, as a lot of bots (Google also) automatically search for sitemaps in the robots.txt file.
If you don’t have a separate robots.txt file on the server, than WordPress automatically generates a virtual robots.txt file with the necessary directives.
This plugin will add the Yoast SEO plugin’s XML Sitemap URL to the virtual robots.txt file, so search bots will find your sitemap and can crawl your site easily.
Multisite Network installs
This plugin is also working on Multisite installs, adding the right sitemap for all your subsites. The plugin checks, if Yoast SEO plugin is activated and if the XML Sitemap is enabled on the sites, so it will add the sitemap URL only, if the sitemap exists.
