Is The Atom Publishing Protocol A Failure?
“The Atom Publishing Protocol is a failure.” Joe Gregorio says, admitting to having met his blogging-hyperbole-quotient for the day. In a post largely about the how the level of adoption that AtomPub is seeing, is far lower than the expectation. Joe writes that “There are still plenty of new protocols being developed on a seemingly daily basis, many of which could have used AtomPub, but don't.”
Joe Attributes the inability of AtomPub to become the “one true protocol”, to browser innovations.
According to Joe some of the key capabilities that AtomPub was designed to address are either easily available as a result of advances in browser technologies or are no longer a significant differentiator:
1. The capabilities of browsers were limited as an “editor” and AtomPub was created to be used by thick clients and RIA’s.
The reality is that more and more functionality is moving into the browser and that takes away one of the driving forces for an editing protocol.
2. AtomPub was designed to address the offline editing scenario.
Another motivation was the "Editing on the airplane" scenario. The idea was that you wouldn't always be online and when you were offline you couldn't use your browser. The part of this cliche that wasn't put down by Virgin Atlantic and Edge cards was finished off by Gears and DVCS's.
3. Serve as a common interchange format.
Joe points to successful implementations of AtomPub in a variety of services, and concludes saying “the advances in browsers and connectivity have conspired to keep AtomPub from reaching the widespread adoption”
Other use cases are still holding up over time, such as migrating data from one platform to another. Probably the biggest supplier of AtomPub based services is Google with the Google Data APIs, but it also has support from other services; just recently I noticed that flickr offers AtomPub as a method to post images to your blog.
Dare Obasanjo, echoes a similar sentiment over at his blog
The growth in popularity of object-centric JSON over document-centric XML as the way to expose APIs on the Web has been the real stake in the heart for the Atom Publishing Protocol.
With Microsoft betting on AtomPub with its cloud offerings and Google invested in it with with the Google Data APIs, it may not be such a failure after all. Joe’s original post is available at is blog.
