It's been a while in the works, but I'm happy to announce that we've update the specification for Simple Sharing Extensions. There are some pretty significant changes to this edition, including:

  • We added an SSE binding to the Atom feed format.
  • We made several changes to the sync algorithm to improve accuracy and efficiency
  • We reorganized the spec to improve readability
  • We removed the OPML binding from the v1 edition of the spec.

I've also updated the FAQ doc to go with the current spec. There are HTML/Javascript based tutorials for both Atom and RSS as well.

For those who are new to the spec, the scope of Simple Sharing Extensions (SSE) is to define the minimum extensions necessary for loosely-coupled applications to use XML-based container formats like Atom and RSS feeds as a way to synchronize a set of items across a distributed mesh of endpoints. In slightly more plain English, that means that you can have a set of applications and services that are all sharing the same underlying data in a loosely coupled way.
