Cannot add base table from module

Hello there,

I've been trying to add my custom modules table as a base table in views. This is how I've tried to implement it:

/mymodule.module

/**
 * Implements hook_views_api().
 */
function mymodule_views_api() {
  return array(
    'api' => 3,
    'path' => drupal_get_path('module', 'mymodule') . '/includes/views',
  );
}

/mymodule.install

/**
 * Implements hook_schema().
 */
function mymodule_schema() {
  
  $schema = array();
   
  $schema['mymodule_domains'] = array(
    'description' => 'Storage for the domains retrieved',
    'fields' => array(
      'id' => array(
        'description' => 'Primary key of the record.',
        'type' => 'serial',
        'unsigned' => TRUE,
        'not null' => TRUE,
      ),
      'domain' => array(
        'description' => 'Domain name.',
        'type' => 'varchar',
        'length' => 255,
        'not null' => FALSE,
      ),
      'type' => array(
        'description' => 'Domain type.',
        'type' => 'varchar',
        'length' => 255,
        'not null' => FALSE,
      ),
      'status' => array(
        'description' => 'Domain status',
        'type' => 'int',
        'length' => 1,
        'not null' => FALSE,
      ),
    ),
    'primary key' => array('id'),
  );
  
  return $schema;
}

/includes/views/domains.view.inc

/**
 * Implements hook_views_data().
 */
function mymodule_views_data() {
  
  $data = array();
  
  // Putting the table into its own groups so that we can recognize in the UI
  // where it comes from
  $data['mymodule_domains']['table']['group'] = t('MyModule');
  
  // Making the 'mymodule_domains' table a base table so a View can created based on it
  $data['mymodule_domains']['table']['base'] = array(
    'field' => 'id',
    'title' => t('MyModule Domains'),
    'help' => t('Contains domains exposed to Views.'),
    'weight' => -10,
  );
  
  // The ID field
  $data['mymodule_domains']['id'] = array(
    'title' => t('ID'),
    'help' => t('The domain ID.'),
    'field' => array(
      'handler' => 'views_handler_field_numeric',
    ),
    'sort' => array(
      'handler' => 'views_handler_sort',
    ),
    'filter' => array(
      'handler' => 'views_handler_filter_numeric',
    ),
  );
  
  // The Domain field
  $data['mymodule_domains']['domain'] = array(
    'title' => t('Domain Name'),
    'help' => t('The domain name.'),
    'field' => array(
      'handler' => 'views_handler_field',
    ),
    'sort' => array(
      'handler' => 'views_handler_sort',
    ),
    'filter' => array(
      'handler' => 'views_handler_filter_string',
    ),
  );
  
  // The Type field
  $data['mymodule_domains']['type'] = array(
    'title' => t('Type'),
    'help' => t('The domain type.'),
    'field' => array(
      'handler' => 'views_handler_field',
    ),
    'sort' => array(
      'handler' => 'views_handler_sort',
    ),
    'filter' => array(
      'handler' => 'views_handler_filter_string',
    ),
  );
  
  // The Status field
  $data['mymodule_domains']['status'] = array(
    'title' => t('Status'),
    'help' => t('The domain status.'),
    'field' => array(
      'handler' => 'views_handler_field_numeric',
    ),
    'sort' => array(
      'handler' => 'views_handler_sort',
    ),
    'filter' => array(
      'handler' => 'views_handler_filter_numeric',
    ),
  );
  
  return $data;
  
}

I have disabled, uninstalled, re-enabled the module then cleared all caches including the views cache, however the table still does not show up as a base table when creating a new view. What am I doing wrong?
