FeedSync

FeedSync, previously Simple Sharing Extensions, are extensions to RSS and Atom feed formats designed to enable the aggregation of information by using a variety of data sources. Initially developed by Ray Ozzie, Chief Software Architect at Microsoft, it is now maintained by Jack Ozzie, George Moromisato, Matt Augustine, Paresh Suthar and Steven Lees. Dave Winer, the designer of the UserLand Software RSS variants, has given input for the specifications.

The standard is currently a work in progress, currently at version 1.0 which was released on December 4, 2007.FeedSync is licensed under the Creative Commons Attribution-ShareAlike License (version 2.5) and the Microsoft Open Specification Promise.

The scope of FeedSync is to define the minimum extensions necessary to enable loosely-cooperating applications to use XML-based container formats such as Atom and RSS as the basis for item sharing – that is, the bi-directional, asynchronous synchronization of new and changed items amongst two or more cross-subscribed feeds.

Examples of Real World Use

Though the specification is still under development there are several examples of "real world" use of SSE to synchronize data between applications.

trong Angel III

SSE was used extensively at the [http://www.strongangel3.net Strong Angel III] exercise in August 2006 as a lightweight middleware to [http://www.strongangel3.net/sse link applications] from Microsoft, Google, ESRI and others on desktops and mobile devices.
