Private Taxonomy Terms Module

With the Private Taxonomy Terms Module it is possible to set vocabulary to 'private'. A private vocabulary allows users to own their own terms in a vocabulary. This associates every term in a private vocabulary with a user. Users with the permission 'administer own taxonomy' can maintain their own terms. This allows a user to create, modify and delete terms associated with them in a private vocabulary. Users with the 'view private taxonomies' permission can view the terms of other users. This allows a user to create content categorized with their terms in a private vocabulary and yet allow other users to see those terms. There also are settings to assign default terms in a private vocabulary to new users or to existing users. The Drupal 7 version of this module is also mature.
