/**
* SECTION: e-source-resource

* @short_description: #ESource extension for a remote resource
*
* The #ESourceResource extension holds the server-assigned identity of a
* remote calendar, address book, or whatever else an #ESource can represent.
*
* This extension is typically used by an #ECollectionBackend to note a
* server-assigned resource identity in an #ESource. Then in a later session,
* after querying the server for available resources, a resource identity can
* be paired with the same #ESource #ESource:uid from the previous session,
* allowing locally cached data from the previous session to be reused.
*
* Access the extension as follows:
*
* |[
* #include <libedataserver/libedataserver.h>
*
* ESourceResource *extension;
*
* extension = e_source_get_extension (source, E_SOURCE_EXTENSION_RESOURCE);
* ]|
