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>.

IndieWeb

Provides a <a href="http://microformats.org/wiki/microformats2-parsing" rel="nofollow ugc">Microformats2 JSON</a> “Feed” for every WordPress URL, and helps to allow other sites to get pre-parsed <a href="https://indieweb.org/jf2" rel="nofollow ugc">Microformats-JSON</a> even if the theme 
does not support Microformats2.
<a href="https://indieweb.org/microformats" rel="nofollow ugc">Microformats2</a> are a key <a href="https://indieweb.org/Category:building-blocks" rel="nofollow ugc">building-block</a> of the IndieWeb, but it is very hard (if not impossible) to get Microformats2 as a core feature for all WordPress themes. There are several themes that are supporting Microformats2, but everyone should choose his prefered theme and should not be limited to use one of the <a href="https://indieweb.org/WordPress/Themes" rel="nofollow ugc">few community themes</a>. After <a href="https://github.com/indieweb/wordpress-uf2/issues/30" rel="nofollow ugc">a lot of discussions</a> and some different plugin approaches, we are trying to provide an alternate (<a href="https://indieweb.org/rel-alternate" rel="nofollow ugc"><code>rel=altenate</code></a>) representation of the microformatted HTML.
The plugin is inspired by the URL design of <a href="https://github.com/aaronpk/p3k" rel="nofollow ugc">p3k</a> of <a href="https://github.com/aaronpk" rel="nofollow ugc">@aaronpk</a>.
p3k Example:
<ul>
<li>Original: <a href="https://aaronparecki.com/2018/07/30/18/xray-updates" rel="nofollow ugc">https://aaronparecki.com/2018/07/30/18/xray-updates</a></li>
<li>Microformats2 JSON: <a href="https://aaronparecki.com/2018/07/30/18/xray-updates.json" rel="nofollow ugc">https://aaronparecki.com/2018/07/30/18/xray-updates.json</a></li>
