Event series dates / Sub-events
===============================

Resource description
--------------------

Events can represent whole event series if the ``has_subevents`` property of the event is active.
In this case, many other resources are additionally connected to an event date (also called sub-event).
The sub-event resource contains the following public fields:

   :query page: The page number in case of a multi-page result set, default is 1
   :query active: If set to ``true``/``false``, only events with a matching value of ``active`` are returned.
   :query is_future: If set to ``true`` (``false``), only events that happen currently or in the future are (not) returned.
   :query is_past: If set to ``true`` (``false``), only events that are over are (not) returned.
   :query ends_after: If set to a date and time, only events that happen during of after the given time are returned.
   :param organizer: The ``slug`` field of a valid organizer
   :param event: The ``slug`` field of the main event
   :query datetime modified_since: Only return objects that have changed since the given date. Be careful: This does not
       allow you to know if a subevent was deleted.
   :query array attr[meta_data_key]: By providing the key and value of a meta data attribute, the list of sub-events
        will only contain the sub-events matching the set criteria. Providing ``?attr[Format]=Seminar`` would return
        only those sub-events having set their ``Format`` meta data to ``Seminar``, ``?attr[Format]=`` only those, that
        have no value set. Please note that this filter will respect default values set on 
        organizer or event level.
   :query with_availability_for: If set to a sales channel identifier, the response will contain a special ``best_availability_state``
                                 attribute with values of 100 for "tickets available", values less than 100 for "tickets sold out or reserved",
                                 and ``null`` for "status unknown". These values might be served from a cache. This parameter can make the response
