The taxonomy is the basis of categories, keywords (tags) and other rankings in WordPress (like language with xili-language trilogy). Since WP 2.3, all key components are found in the file wp-includes / taxonomy.php. WP 4.4 release announces a big change. The developer will seek information in 3 files:
* Core Taxonomy API

/** Core taxonomy functionality */
require_once( ABSPATH . WPINC . '/taxonomy-functions.php' );
/** WP_Term class */
require_once( ABSPATH . WPINC . '/class-wp-term.php' );
/** WP_Tax_Query class */
require_once( ABSPATH . WPINC . '/class-wp-tax-query.php' );
including the new wp-term class that strengthens the previous object describing the terms methodically …
