The Open Graph protocol enables any web page to become a rich object in a social graph. For instance, this is used on Facebook to enable any web page to have the same functionality as a Facebook Page.
While many different technologies and schemas exist and could be combined together, there isn’t a single technology which provides enough information to richly represent any web page within the social graph. The Open Graph protocol builds on these existing technologies and gives developers one thing to implement. Developer simplicity is a key goal of the Open Graph protocol which has informed many of the technical design decisions.
<h4>For Developers</h4>
Use <code>add_action('open_graph_head_pre','your_function');</code> and <code>add_action('open_graph_head_post','your_function');</code> to edit the meta data. For an instance of the class.
Always use <code>open_graph_instance()</code>

Open Graph WP implementation

Implements the Open Graph Protocol on a WordPress installation. Can be used by other plugins as a dependency.

This plugin will query the popular social network APIs and retrieve the number of shares/likes/plusones from each. All shares are added up and calculated together to give you the total number of shares. All that is returned is a simple number. This number represents the number of shares, likes, tweets, +1’s, and pins.
The plugin can be utilized two ways, the first method is the AJAX route which will require you to add a little javascript to your template. This method is the preferred method if you are requesting the share count for multiple posts on one page load. For example on an archive page. Below is a quick example of how that is done:
<pre><code>jQuery.get(ajaxurl, { action: "get_total_shares", url: "<?php the_permalink(); ?>" }).done(function(data) { var shareNum = parseInt(data); // your total number of shares }); </code></pre>
Note: You can call this AJAX anyway you wish, but you must pass <code>the_permalink();</code> as the <code>url</code> parameter and <code>"get_total_shares"</code> for the <code>action</code> parameter.
If you are just displaying the share count for one post at a time, you may use the plugin shortcode to return the number. That shortcode is <code>[tyme_share_count]</code>
This plugin also refreshes the Facebook Open Graph scraper each time a post is published. This ensures the proper images and content are being served to Facebook when shared.

Tyme Social Count

Calls popular social network APIs and returns a total share/like/+1/tweet/pin count from Facebook, Twitter, LinkedIn, Google Plus and Pinterest.
