Drupal 7: Assigning vocabularies with Field API

This took me far too long to figure out, but here's how you create a vocabulary, and then a taxonomy field and instance, all through an .install file (or anywhere else you really care to put it). Took a bunch of debugging before I hit on the right magical combination. This is part of a demo I'm working on for the Drupal 7 and FRBR mental model I published last night.

  $libdb_vocabulary_endeavorers = (object) array(
    'name'          => 'Endeavorers',
    'machine_name'  => 'libdb_endeavorers',
    'description'   => t('FRBR Group 2 entities: Persons and Corporate Bodies.'),
    'help'          => t('Enter a comma-separated list of persons or corporations.'),
  );
  taxonomy_vocabulary_save($libdb_vocabulary_endeavorers);

  $vocabularies = taxonomy_vocabulary_get_names();

  $libdb_m_group2_field = array(
    'field_name'  => 'libdb_m_authors',
    'type'        => 'taxonomy_term',
    'cardinality' => FIELD_CARDINALITY_UNLIMITED,
    'settings' => array(
      'allowed_values' => array(
        array(
          'vid'     => $vocabularies['libdb_endeavorers']->vid,
          'parent'  => 0,
        ),
      ),
    ),
  );
  $libdb_m_group2_instance = array(
    'field_name'  => 'libdb_m_authors',
    'object_type' => 'node',
    'label'       => 'Authors',
    'bundle'      => 'libdb_book',
    'required'    => TRUE,
    'description' => t('Enter a comma-separated list of persons or corporations.'),
    'widget' => array(
      'type' => 'taxonomy_autocomplete',
    ),
  );
  field_create_field($libdb_m_group2_field);
  field_create_instance($libdb_m_group2_instance);
