+# Allow users to add additional/custom properties to images.
+#
+# Glance defines a standard set of properties (in its schema) that
+# appear on every image. These properties are also known as
+# ``base properties``. In addition to these properties, Glance
+# allows users to add custom properties to images. These are known
+# as ``additional properties``.
+#
+# By default, this configuration option is set to ``True`` and users
+# are allowed to add additional properties. The number of additional
+# properties that can be added to an image can be controlled via
+# ``image_property_quota`` configuration option.

+# Setting this option to ``glance.db.registry.api`` will force all

+#
+# NOTE: In v2 OpenStack Images API, the registry service is optional.
+# In order to use the Registry API in v2, the option
+# ``enable_v2_registry`` must be set to ``True``.
+#
+# Finally, when this configuration option is set to

+# cached images, fetch size of the cache, queue images for caching and
+# clean up
+# the cache, etc.
+#
+# The essential functions of a driver are defined in the base class
+# ``glance.image_cache.drivers.base.Driver``. All image-cache drivers
+# (existing
+# and prospective) must implement this interface. Currently available
+# drivers
+# are ``sqlite`` and ``xattr``. These drivers primarily differ in the
+# way they
+# store the information about cached images:
+# * The ``sqlite`` driver uses a sqlite database (which sits on
+# every glance
+# node locally) to track the usage of cached images.
+# * The ``xattr`` driver uses the extended attributes of files to

+# Upon receiving the request to cache an image, Glance touches a file
