Blogging Roller: What exactly is RSS anyway?

What exactly is RSS anyway?

Is it this http://cyber.law.harvard.edu/rss/rss.html, promoted by Dave Winer?

This http://www.rssboard.org/rss-specification, from the RSS advisory board?

Or one of the other dozen or so incompatible formats.

It doesn't really matter. There's only one Atom: RFC-4287.

Hat tip to Sam Ruby.

Actually, there are two versions of Atom and they are incompatible. All versions of RSS 0.9x and 2.0 are compatible with each other. Nice lie.

I maintain that there is one version of Atom and that is RFC-4287. Some folks made the mistake of implementing Atom 0.3, which was clearly marked do not implement. As far as RSS compatibility is concerned, it depends on what your definition of compatible is. No lie.

The spec we're publishing and the spec Dave Winer has archived contain zero differences in RSS elements and attributes and how they are described. I don't want to get into an Atom vs. RSS thing, because I like Atom. But when Atom 0.3 was published, it sparked a lot of implementations, including some by leaders of the project. Was it really a mistake on their part, or was it an obvious consequence of how Atom 0.3 was released?

Dave, an RSS 0.91 still works with little problem in an RSS 2.0 parser. That's called compatibility. The fact you suggest otherwise indicates you can't get passed your biased.

Where compatibility equals "works with little problem" I'll agree with you. I'll also agree with you on this: I am biased towards Atom.
