<p>The <code>$mod</code> variable is defined early in the load process (in <code>WpssoHead-&gt;show_head()</code>, which is hooked to the 'wp_head' action) and is passed to most WPSSO methods and filters.</p>

<pre>
$wpsso =&amp; Wpsso::get_instance();

// In case we prefer using the global $post object.
$use_post = apply_filters( 'wpsso_use_post', in_the_loop() ? true : false );

// Get information about the current webpage.
$mod = $wpsso-&gt;page-&gt;get_mod( $use_post );
</pre>

<p>The <code>$mod</code> variable name stands for <em>module</em> and defines important reference values for the current WPSSO object type. The WPSSO object type can be a comment, post, term, or user object. An archive does not have an object type since an archive page is a collection of objects. For example, a monthly archive is a collection of posts for that month. In this case, <code>$mod[ 'obj' ]</code> would be false and other properties like <code>$mod[ 'is_archive' ]</code>, <code>$mod[ 'is_date' ]</code>, and <code>$mod[ 'is_month' ]</code> would be true.</p>

<p>The <code>WpssoPage-&gt;get_mod()</code> method can be used to determine the current webpage module. If you need to setup a <code>$mod</code> variable for a specific comment, post, term, or user, you can call the <code>get_mod()</code> method from those class objects.</p>

<pre>
$wpsso =&amp; Wpsso::get_instance();

// Get information for comment ID 123.
$mod = $wpsso-&gt;comment-&gt;get_mod( $comment_id = 123 );

// Get information for post ID 123.
$mod = $wpsso-&gt;post-&gt;get_mod( $post_id = 123 );

// Get information for term ID 123.
$mod = $wpsso-&gt;term-&gt;get_mod( $term_id = 123 );

// Get information for user ID 123.
$mod = $wpsso-&gt;user-&gt;get_mod( $user_id = 123 );
</pre>

<p>Functions to get the <code>$mod</code> array are also available:</p>

<pre>
// Get information about the current webpage (post, term, user, archive page, etc.).
$mod = wpsso_get_page_mod();

// Get information for comment ID 123.
$mod = wpsso_get_comment_mod( $comment_id = 123 );

// Get information for post ID 123.
$mod = wpsso_get_post_mod( $post_id = 123 );

// Get information for term ID 123.
$mod = wpsso_get_term_mod( $term_id = 123 );

// Get information for user ID 123.
$mod = wpsso_get_user_mod( $user_id = 123 );
</pre>
