"There is more than one way to do it." This philosophy isn’t limited to Perl; it generally extends to open source software itself. Likewise, there are four modules that are intended to integrate taxonomy fields into the Content Construction Kit (CCK) for Drupal; these modules have been identified to have similar or overlapping functionality. Below is a list of the 4 modules.

• Content Taxonomy (content_taxonomy)
• CCK Taxonomy Fields (cck_taxonomy)
• Taxonomy Super Select (taxonomy_super_select)
• CCK Taxonomy Super Select Ultra (cck_taxonomy_ssu)

This document serves to compare and contrast these modules in order to make it easier for site owners to choose one to suit their site development needs. The following issues are addressed for each module:

• ease of installation and ease of use
• list of any dependencies or companion modules associated with each module (CCK, Taxonomy, Views, API modules, externally hosted code, etc.)
• features and functionality
• pros and cons
• list of access permissions
• evaluation of the documentation/handbook (if any)
• status of the most stable release (development, alpha, beta, official)
• if it is still in development, an evaluation for its potential for successful completion
• a brief examination of the its issue queues for any glaring or recurring problems
