obspy.core.event - Classes for handling event metadata
======================================================
This module provides a class hierarchy to consistently handle event metadata.
This class hierarchy is closely modelled after the de-facto standard
format `QuakeML <https://quake.ethz.ch/quakeml/>`_.

.. note::

    For handling additional information not covered by the QuakeML standard and
    how to output it to QuakeML see the :ref:`ObsPy Tutorial <quakeml-extra>`.
