Overview of RSS 2.0

RSS is a dialect of XML, and is used for syndicating Web content and metadata. RSS 0.91 is the most commonly used of several versions available. For new RSS feeds, it's better to use version 2.0 because it is the current spec and, as mentioned above, it's backward compatible with 0.91.
Dave Winer authored version 2.0 of the spec. He intentionally avoided changes to the specification that would make it more difficult to use, or that would break existing applications. Winer sums up his philosophy like this: "Keep it simple. That's the value of RSS. Anyone who can understand a little HTML can understand RSS. That's important!"
The spec is published under a Creative Commons license. This means that you're free to copy and distribute the spec, make derivative works, and to use it freely in commercial work. An advisory board is responsible for updating the spec, advocating for it, and documenting it.
