FeedSync for Atom and RSS, previously Simple Sharing Extensions, are extensions to RSS and Atom feed formats designed to enable the synchronization 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 specification variants, has given input for the specifications. The current version of FeedSync for Atom and RSS specification is 1.02 can be found (here ). FeedSync for Atom and RSS is licensed under the Creative Commons Attribution-ShareAlike License (version 2.5) and the Microsoft Open Specification Promise. The scope of FeedSync for Atom and RSS is to define the minimum extensions necessary to enable loosely cooperating applications to use Atom and RSS feeds 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. Note that while much of FeedSync is currently defined in terms of Atom and RSS feeds, at its core what FeedSync strictly requires is: *A flat collection of items to be synchronized *A set of per-item sync metadata that is maintained at all endpoints *A set of algorithms followed by all endpoints to create, update, merge, and conflict resolve all items ''This means that FeedSync can be implemented by almost any programming language have its metadata represented in many structured data formats.'' ==Examples== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「FeedSync」の詳細全文を読む スポンサード リンク
