class ForumVocabulary

Checks if the vocabulary being migrated is the one used for forums.

Drupal 8 Forum is expecting specific machine names for its field and vocabulary names. This process plugin forces a given machine name to the field or vocabulary that is being migrated.

The 'forum_vocabulary' source property is evaluated in the d6_taxonomy_vocabulary or d7_taxonomy_vocabulary source plugins and is set to true if the vocabulary vid being migrated is the same as the one in the 'forum_nav_vocabulary' variable on the source site.

Example:

process:
  field_name:
    plugin: forum_vocabulary
    machine_name: taxonomy_forums

Plugin annotation

@MigrateProcessPlugin(
  id = "forum_vocabulary"
)
