Atom 1.0 vs RSS 2.0

heeeraldo writes "Is there another format war on the horizon? This wiki compares the two, and finds that even though RSS has far greater deployment (and mindshare), Atom 1.0 solves a lot of the problems associated with it."

  1. Atom's More Than A Syndication Format by arthurs_sidekick · · Score: 5, Informative

    Atom is both a syndication format and an API for creation, updating, and deletion of content. It's already in widespread use by Blogger.

    What's been (all but) finalized is the syndication format (and rules for extending it). This allows the working group to firm up the details of the publishing API, which, for my money, is the real payoff with Atom.

    A pretty good overview of the history of RSS and the motivations behind Atom is here.

  3. Re:I would consider... by superskippy · · Score: 5, Informative

    RSS and Atom are standardised ways of having a live list of stories appear from say a newssite (like this one) in various programs. Firefox calls these live bookmarks. I came here using firefox by clicking on my toolbar, seeing all of the new stories, and deciding I was interested in this one. You can also use it for desktop "news ticker" applets.

    The trouble with RSS (short answer) is that there are at least three different versions of it invented by different people. As far as I know there was an RSS 0.7, then someone else invented a new protocol and called it RSS 1, then the original person invented RSS and called it version 2, but some people argue 2 is worse than 1 :(. All of these standard's owners have been accused of not taking on board comments from the wider community.

    Atom is another protocol for doing the same thing. Technical issues aside, it gets my vote because they didn't decide to call it RSS 3. Or RSS 10.

  4. Parent Makes No Sense by samael · · Score: 4, Informative

    Atom isn't forked off of RSS, it's another implementation of the concept of syndicated content. RSS itself isn't a concept, it's a specification for a data transfer format.

    The parent post really doesn't make any sense at all.

  5. Re:Where's the comparison? by Isofarro · · Score: 4, Informative

    Atom cleanly specifies how to incorporate plain text, html and XHTML content in an entry. Covering how text and html needs to be escaped, etc.

    RSS2.0 had a problem last year where Reuters suffered a public embarrassment adopting the format. They followed the specification correctly, and it resulted in silent data loss - their stock identifiers were in angled brackets and got treated as an HTML tag by news aggregators.

    It wasn't rocket science, but this simple thing turned out to be impossible to do with RSS2.0 - it was tried many times. After the funky feed debacle, the community realised that a separate format independent of RSS2.0 was the only way to fix the underlying problem.

    The proponents of RSS2.0 tried to fix the silent data loss, and ended up breaking backwards compatibility with RSS0.92 - something they weren't prepared to do before Atom.

  6. As someone who's implemented them both by savala · · Score: 4, Informative

    Atom wins hands-down. Things are actually well specified .
    I can just walk through the atom specification, implementing it as I go, and not have any questions about what is required, what type of content can be present in any one element, I don't have to look up five even less well-specified different modules just to get the basics of the feed together (and thus also don't have to worry about namespaces), what elements and attributes mean (actually, I spent a minor five minutes agonizing over what I should put in the term atribute of the category element, given that the label attribute contains the human readable version, before realizing that I was completely free in this, as the "scheme" os up to myself, and deciding to mirror how categories are named in the url on the website (which I found to be consistent with various other already existing atom 1.0 feeds that I checked)), or... well, basically any kind of question that you need to think about as you implement a new and previously unknown specification.

    RSS on the other hand (any of the 9 incompatible versions)... *shudders* Those specifications don't tell me anything. I copy/paste from other feeds and heavily use the feedvalidator, but... *shakes his head*
    Once all feedreaders have been updated to support Atom 1.0 completely, I'll go and pull the plug on the remaining RSS feeds, and good riddance too!
