Important note: The News Repository APIs have been deprecated from the 4.0 release. These APIs are still functional for backward compatibility reasons - but no new feature is surfaced through these APIs. For any new development work, please refer to the OpenSocial Activity Stream APIs.
When you are viewing the latest updates listed on the Home page, you can mark an update as something you would like to read later by saving it as a saved story. A person's saved stories are listed in a collection. If you plan to update that collection using the resources made available through the Atom APIs, you must first retrieve the user's saved stories service document.
