Taxonomy Everywhere

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.

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!


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


anjaliforberpratt.com/photos/Beijing-Paralympic-Games

That links to the album
that the photo is in.

It gets a nice name
thanks to the View
Alias module,
drupal.org/project/
view_alias


Clicking the photo brings one to the album, rather than the individual
photograph.


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, cont.

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