Content Taxonomy

This module provides a CCK field type for referencing taxonomy terms.
The fields are independent from vocabulary settings. For every field you can specify following settings:

• widget type (see list below)
• general CCK settings (label, description, fieldgroup, weight, single/multiple, required, ...)
• the vocabulary to use
• further settings for hierarchical vocabularies, like the depth of the tree or a parent term for sub-trees
• storage settings: storage is done in the CCK tables. But for many modules it's necessary, that the saved values are also available to the core Taxonomy system. In this case it's possible to save values additionally to the core taxonomy database table. (Drupal 6)
• widget-specific settings

Content Taxonomy is going to hide all form fields from the core Taxonomy module from vocabularies, which are handled by a Content Taxonomy field (since Beta 6).

Further Content Taxonomy Fields have Views and Token support and can be used with Rules.

At the moment there are following widgets available:

• Select lists
• Radio Buttons / Checkboxes (depending if single or multiple field)
• Autocompletes (supports Active Tags)
• Hierarchical Select
• Activeselect (Drupal 5 only)
• Taxonomy Tree - requires the Taxonomy Manager (Drupal 6 only)
• Multiselect

A good comparison between the different CCK/Taxonomy Modules is available here.

Migration from D6 to D7 Term Reference Fields:
- first backup your DB
- run the core upgrade path
- download and install the Content Migrate (CCK) module
- download and install the Content Taxonomy Migrate module
- goto Structure > Migrate and select your fields to upgrade
- clear caches
- check if the data is available or rollback

note: the Content Taxonomy module in D7 allows you to select the parent term in the field settings, but all other advanced settings will be lost when upgrading.
