Microsoft said they will also support ATOM in Longhorn. http://www.winfuture.de/news,21461.html [winfuture.de] - I can't find an english news.

So all feeds supported in Longhorn will be:
RSS 0.9x
RSS 1.0
RSS 2.0
ATOM 0.3
ATOM 1.0

Re:No question (2, Informative)

Isofarro (193427) | more than 9 years ago | (#13093180)

Not exactly true. Microsoft have confirmed that their Longhorn RSS plans does include handling Atom. They have thrown their weight behind RSS as in syndication, not RSS as the file format.

Well it's not being able to see news articles in one place thats the big deal. If you are someone that has a regular group of web sites you check every day, say Slashdot, Register, MSDN blogs, your ex-girlfriend's blog etc... you don't have to manually visit every site to see if content has been updated and if it interests you. You just glance at some feeds real quick to see if interesting content has been updated.

superskippy (772852) | more than 9 years ago | (#13093038)

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.

Re:I would consider... (1)

SteveX (5640) | more than 9 years ago | (#13093227)

The claim that there are multiple incompatible versions of RSS is used as a way to try to make RSS look bad. I've written code to interpret an RSS feed, and I don't have any switching based on the version of RSS it is... I do have to figure out what to use as a unique identifier based on some heuristics, but that's not because there's multiple versions, it's because the spec intentionally allows you to include a minimum number of tags.

If you don't like something about a protocol, is the correct thing to do to revise the protocol? I think so... many of the Internet protocols we use have changed over the years, some of them in incompatible ways. Doesn't mean we have to toss them and make new ones.

The trouble with RSS (short answer) is that there are at least three different versions of it invented by different people.
The most complete history I've seen of the many different RSS variants can be found in Mark Pilgrim's essay, The myth of RSS compatibility [diveintomark.org] . As of early 2004, there were (by Mark's count) nine incompatible document formats all calling themselves "RSS" of one version or another.

It's easy to see why developing a robust feed parser [feedparser.org] is a real challenge (albeit a necessary one, to hide the current standards chaos from users).

Re:Where's the comparison? (4, Informative)

Isofarro (193427) | more than 9 years ago | (#13093292)

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.

TheRaven64 (641858) | more than 9 years ago | (#13093217)

Slashdot has the most broken RSS feed ever invented. You get banned for 72 hours if you access it more than once every 30 minutes. Not really a problem, except that Slashcode is braindead at identifying individuals. Two computers behind a NAT are treated as the same person, for example. Worse, my ISP uses a transparent proxy for everyone in my city (most people here with broadband use my ISP, since their cable service is a lot cheaper than competing ADSL suppliers). Does Slashdot recognise this? No, they block the transparent proxy whenever more than one person using it accesses the site within a 30 minute period. Clever, huh? The result is that the Slashdot feed is always blocked for me at home.

The RSS 2.0 specification is copyrighted by Harvard University and is frozen. No significant changes can be made and it is intended that future work be done under a different name; Atom is one example of such work.

This is the point: Atom is just a fork. RSS is a real concept. Forks come and go, a concept stands.

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.

Re:whoa nelly (0)

They are both file formats. Neither are concepts. Atom isn't a type of RSS, it's just that RSS got to the buzzword finishing line before Atom. Atom isn't a fork, it's a replacement.

Atom was created to address the deficiencies in RSS. Unsurprisingly, it's better than RSS. If it wasn't, then there wouldn't have been much point in creating it, would there?

Look at wikipedia (1)

quake74 (466627) | more than 9 years ago | (#13093361)

The article in wikipedia on RSS [wikipedia.org] is more balanced.

The fight between Atom and RSS2.0 was fueled for a while from (in my opinion) a clash of egos between Mark Pilgrim and Dave Winer. Nowadays heads are cooler and there might be some kind of standardization in the long end.

In passing, look at the interesting rant [scripting.com] by Dave Winer in his blog not too long ago.

Once again (5, Insightful)

Bad to the Ben (871357) | more than 9 years ago | (#13092916)

Back to the VHS Vs. Betamax days eh? If there's one thing that war proved, it's that technical sophistication is irrelevant: mindshare is what matters. If nobody's using it, it doesn't matter if it has the prettiest widgets.

That said, one nice thing about this format war is that there doesn't have to be a loser. It's fairly easy to handle multiple formats in software (note the number of redundant music formats), unlike hardware which is usually impossible. If the process of reading RSS tags or Atom tags is made transparent to the user, who cares who wins?

Re:Once again (3, Insightful)

$RANDOMLUSER (804576) | more than 9 years ago | (#13093016)

The difference, in this case, is that the decision to use RSS or Atom will be made by the website operators, not the end consumers. The consumers will use what the webmasters use. And I'm thinking that the webmasters will be attracted to the features rather than the ubiquity of a particular format.

If this was a VHS versus Betamax style debate than one standard would be proprietary and carry heavy licensing fees. That, and the shorter recording times, are the reasons why Beta lost out to VHS. This issue is simply a question of whether or not a derivative standard improves on, and thus should replace, a previous standard.

You typed `mindshare` when you meant to type `sales`. Mindshare is a metric used to work out what a company was worth during the amusing blip that was the "dot-com boom". You don't need to use the word any more - it's lost any credibility it ever had.

Atom's More Than A Syndication Format (5, Informative)

arthurs_sidekick (41708) | more than 9 years ago | (#13092934)

Atom is both a syndication format and an API [bitworking.org] 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 [computer.org] .

Besides industry support, my only question would be "which one is growing?" Which of these formats is expected to get a new version number sometime soon?
If you ask me, that is why Microsoft is talking about adding "extensions" to RSS -- by growing and adapting the standard, it gets more bells and whistles, more application support, and more momentum in the development community.

Re:Who cares? (1)

Rits (453723) | more than 9 years ago | (#13093452)

Atom has the advantage of having a very well defined spec. The user agent doesn't have to guess if pointy brackets are content or markup. By using Atom, as a producer you will probably be better off, because you can trust the user agents to get it right. And for the same reason, it will be easy for user agents to support Atom (easier than supporting the numerous RSS variants) so there is little doubt every serious user agent will support Atom in the near future.

That doesn't mean it will take over from RSS 2.0 any time soon, but it will be a pretty riskless change.

RSS 2.0 vs. Atom vs. RSS 1.0 (4, Insightful)

Feneric (765069) | more than 9 years ago | (#13093101)

AFAIK the format war between RSS 2.0 and RSS 1.0 hasn't even ended yet. In spite of the version numbering, RSS 2.0 is more of a .95 than a 2.0 since it's an incremental improvement over .94. It doesn't really add any capabilities to RSS 1.0 (both can support enclosures). The only real difference is that RSS 1.0 is based on RDF while 2.0 isn't; this supposedly makes 2.0 simpler, but potentially less capable.

It's a pity that all the RSS folks couldn't simply hash together a common standard rather than wasting time on competing standards. Is 2.0 really that much simpler than 1.0? Is 1.0 really that much more capable than 2.0? Does Atom really add much to the mix? It seems that it ought to be possible to find a middle ground.

One thing that really bothers me about RSS, no matter how much I like it, is how every site uses it differently. I was writing a simple aggregation program and using php/magpierss. Every single site puts the date and time of the items in a different tag. Some use datetime, some use pubdate, some use dc->date and some don't put the date! Seriously, no matter the standard it wont help if not everyone uses it fully and properly.

GUID (3, Interesting)

SteveX (5640) | more than 9 years ago | (#13093157)

For the most part it doesn't matter which you use because client software is going to have to work with both now that they've both been deployed (and for a while Google was only publishing Atom, I'm not sure if they still do that but it forced aggregator developers to get on board).

But because an Atom feed must include a guid element, the client has a way of uniquely identifying an item. This means that when you subscribe to an atom feed, you're not going to see duplicate articles the way you do with RSS when the RSS feed doesn't include a guid or any unique identifier (which is legal) and the client has to make one up by hashing the content.

I wrote a bit about this here [stevex.org] .

/second that

as long as rss doesn't require you to at least include blank versions of standardized tags we will have the same problems that html has. lots of people out there writing bad code that don't work well for the diversity of readers.

False dichotomy (1)

metamatic (202216) | more than 9 years ago | (#13093172)

Most of the problems with RSS 2.0 that the article points out, are fixed in RSS 1.0.

For those who don't know, RSS 0.9x was basically Dave Winer's personal plaything. When the standards community put together an RSS 1.0 standard, he took his most recent 0.9x 'standard' and renamed it RSS 2.0 to make it look more up-to-date.

Why not take RSS 1.0 and fix the few problems it has?

We can go on and on about the Atom and RSS war. But let me introduce you to something that uses the power of both. Please note that I'm not advertising my site.. I'm talking about Newster.net [newster.net] only because it is very relevant to this discussion.

Newster is aggregatates news from many websites that publish them in RSS. Once the news bits are in the database it uses the ATOM API to post it to the blog. And then it republishes it in ATOM (because its a blogger service). So what we have here is a website that publishes a new news every 15 minutes. No humans here.. and the cool thing is that RSS gets converted to ATOM. Its very easy to write such scripts... so why even fight??

software suggestion for software front page (1)

tolonuga (10369) | more than 9 years ago | (#13093199)

opensc.org has a front page with mostly news entries. I'd like to move from the manualy written php code to some software, where we
can publish announcements on new versions, and atom and/or rss feed would be nice. any suggestion?

All this format commotion just adds more work for programmers. And not a good kinda work either!

It isn't so hard to parse rss or atom, but to do both you pretty much have to separate it out and that might mean twice the code. Pretty lame. You can fake it on the differences between versions of rss if you don't mind leaving stuff out... I tried to fake it on the differences between atom and rss, seemed to work just fine, until I started comparing what it should look like with what it did!

I thought I was gonna be smart and maintain a feed for my personal site. When I finally got sick of trying to explain to all my relatives and friends about what rss is and how they could easily see what updates had been made... My feed's use became limited to listing updates on the front page of that site.

** by the way, for those interested, I just killed firefox- it died after I refused to accept a certificate for some site that I had already closed the tab for. I think firefox is still trying to figure out what to do about the refusal...

No e-mail obfuscation? (1)

baadger (764884) | more than 9 years ago | (#13093367)

Has anyone noticed none of these standards have any form of e-mail obfuscation, or any support for contact methods that protect publishers from harvesting?

Okay, tell me how you plan on implementing that in a standardized way that prevents spammers from retreiving email addresses but allows everyone else to?
