Adds the <a href="http://visitmix.com/Lab/oomph" rel="nofollow ugc">Oomph Microformats toolkit</a>‘s microformat overlay to any WordPress-generated pages (as long as the page has a <a href="http://microformats.org/" rel="nofollow ugc">microformat</a> in it, of course).
This plugin is pretty idiotic (by which I mean brain-dead simple), but it does enable anyone to fully microformat-enable their blog with purely point-and-click operations. It’s recommended that you start with <a href="https://wordpress.org/extend/themes/tags/microformats" title="Check out the various WordPress themes that support microformats out of the box!" rel="ugc">a WordPress theme that already has built-in support for microformats</a>, and then add this plugin to the mix.
Alternatively, if you are comfortable with template code, you can write your own microformats into your custom template. Learn more <a href="https://codex.wordpress.org/Blog_Design_and_Layout" rel="nofollow ugc">about authoring and customizing WordPress templates at the Codex</a>.
Please note that all this plugin does is adds the Oomph toolkit’s functionality to a page. What that means is that the plugin has all the features and benefits, as well as all the limitations, of the Oomph toolkit. Most notably, the plugin only recognizes the <a href="http://microformats.org/wiki/hcard" rel="nofollow ugc">hCard</a> and <a href="http://microformats.org/wiki/hcalendar" rel="nofollow ugc">hCalendar</a> microformats for now.
If you want to send patches to improve this plugin, <a href="http://maymay.net/blog/2008/11/11/wp-oomph-add-the-oomph-microformat-overlay-to-your-wordpress-blog/" title="I welcome your input and code submissions!" rel="nofollow ugc">please do</a>.

Wikidata References for WordPress

Really liked this plugin. Useful. Doesn't add unnecessary taxonomies. Would be interested in seeing what other features it could add. Authors with Wikipedia pages or Wikidata entries could be linked as well from their profiles. 

One of the few plugins that seems to get the core idea really well.

Very excellent
