Retrieve extended resources or attributes for core resources.

Extended attributes are implemented by a core plugin similarly to the attributes defined in the core, and can appear in request and response messages. Their names are scoped with the extension’s prefix. The core API version is passed to this function, which must return a map[<resource_name>][<attribute_name>][<attribute_property>] specifying the extended resource attribute properties required by that API version.

Extension can add resources and their attr definitions too. The returned map can be integrated into RESOURCE_ATTRIBUTE_MAP.

classmethod get_name()

The name of the extension.

e.g. ‘Fox In Socks’

classmethod get_namespace()

The XML namespace for the extension.

e.g. ‘http://www.fox.in.socks/api/ext/pie/v1.0

classmethod get_plugin_interface()

Returns an abstract class which defines contract for the plugin.

The abstract class should inherit from extesnions.PluginInterface, Methods in this abstract class should be decorated as abstractmethod

classmethod get_resources()

List of extensions.ResourceExtension extension objects.

Resources define new nouns, and are accessible through URLs.

classmethod get_updated()

The timestamp when the extension was last updated.

e.g. ‘2011-01-22T13:25:27-06:00’


Update attributes map for this extension.

This is default method for extending an extension’s attributes map. An extension can use this method and supplying its own resource attribute map in extension_attrs_map argument to extend all its attributes that needs to be extended.

If an extension does not implement update_attributes_map, the method does nothing and just return.
