== Model metadata == Model metadata is "anything that's not a field", such as ordering options (ordering), database table name (db_table), or human-readable singular and plural names (verbose_name and verbose_name_plural). None are required, and adding class Meta to a model is completely optional. A complete list of all possible Meta options can be found in the [http://docs.djangoproject.com/en/dev/ref/models/options/#ref-models-options model option reference].
