Taxonomy Groups

Simplifies management of big taxonomies with huge number of terms by putting them into groups (by semantic or any other attribute or criterion).

It creates the Groups vocabulary (so the group is just a term in this vocabulary) and then uses the term_relation Drupal DB table to put terms into groups (as the related terms feature is mostly of no use in Drupal 6 and was removed from Drupal 7).
Bulk operations (put/move terms into group and merge terms) are done through the Views Bulk Operations (module comes with one default view).
So instead of looking at the whole list of all the terms in vocabulary, you can put terms into separate groups and manage them inside the groups.

Dependencies:

• Taxonomy
• Views Bulk Operations

So the module creates user interface at admin/content/taxonomy_groups (restricted by the 'administer taxonomy' permission). It lists all the created groups, allows to add new group (you can also do this by managing Taxonomy Groups vocabulary) and then lists all the terms by groups allowing to drill down into any group and move terms into/between them, merge terms and delete any term.
By default, all the terms from all the vocabularies are included in this view, and you can restrict them by overriding the default view 'taxonomy_terms_by_groups' (adding filters). Or you can create new displays or your own view with these actions, possibilities are limitless.
