Drupal core is the "stock" installation of Drupal, which can be optionally extended by third party contributions. In Drupal's default configuration, website content can be contributed by either registered or anonymous users (at the discretion of the administrator) and made accessible to web visitors by a variety of selectable criteria including by date, category, searches, etc. Drupal core also includes a hierarchical taxonomy system, which allows content to be categorized or "tagged" with key words for easier access.[1]
