# openstack.identity.v3.system

## The System Class

The `System` class inherits from `Resource`.

class openstack.identity.v3.system.System(_synchronized=False, connection=None, **attrs)

  The base resource

  Parameters:

    - _synchronized (bool) – This is not intended to be used directly. See `new()` and `existing()`.

    - connection (openstack.connection.Connection) – Reference to the Connection being used. Defaults to None to allow Resource objects to be used without an active Connection, such as in unit tests. Use of `self._connection` in Resource code should protect itself with a check for None.

  base_path = '/system'

    The base part of the URI for this resource.
