What is taxonomy (bart)

What is taxonomy in Drupal 6?

"The taxonomy module allows you to categorize your content using both tags and administrator defined terms. It is a flexible tool for classifying

content with many advanced features."

People need to categorize, tag, sort, and otherwise organize stuff.

Administrators need to set it up so that other people who did not attend this session can also

categorize and tag.

Use cases of taxonomy

Taxonomy for Photo Gallery

Categorize your pictures into albums

No need to create the album first

Technique courtesy Dan Hakimzadeh (Agaric) and whoever he stole it from.

Taxonomy for Photo Gallery, cont.

● Not necessary for this demonstration, but we have three vocabularies here!

Taxonomy for Photo Gallery, cont.

You can create new photo albums on the fly, or select an existing one from autocomplete dropdown.

That links to the albumthat the photo is in.

It gets a nice namethanks to the ViewAlias module,drupal.org/project/view_alias

Taxonomy for Photo Gallery, cont.

Clicking the photo brings one to the album, rather than the individualphotograph.

Taxonomy for Photo Gallery, cont.

The same view can be used to show photos from different vocabularies.In addition to the event-based albums, you can instantly get category(such as Outreach, shown here) or even keyword-based albums.

Taxonomy for Everything

Most of the content types have corresponding vocabularies. In thiscase, we create a web link and through the power of free tagging adda new person to our categorization, which immediately will work forfaceted search and everywhere else we use taxonomy.

Taxonomy in Drupal 7

Taxonomy entities

/** * Implement hook_field_info(). * * Field settings: * - allowed_values: a list array of one or more vocabulary trees: * - vid: a vocabulary ID. * - parent: a term ID of a term whose children are allowed. This should be * '0' if all terms in a vocabulary are allowed. The allowed values do not * include the parent term. * */function taxonomy_field_info() { return array( 'taxonomy_term' => array( 'label' => t('Taxonomy term'), 'description' => t('This field stores a reference to a taxonomy term.'), 'default_widget' => 'options_select', 'default_formatter' => 'taxonomy_term_link', 'settings' => array( 'allowed_values' => array( array( 'vid' => '0', 'parent' => '0', ), ), ), ), );}

Trees can be whole vocabularies or just pieces.
