A brief Introduction to the Atom Publishing Protocol has been published on the AtomEnabled.org web-site. An HTML version of RFC 5023 is also available, based on the work of Julian Reschke.

The US Intelligence Community Metadata Working Group has issued a recommendation that the Intelligence Community, over time, move toward adoption of Atom Syndication Format as the Community’s standard XML-based language for syndication feeds.

James Snell has posted instructions on how you can produce valid Atom 1.0 feeds with WordPress.

Dave Johnson gave an excellent talk on the Atom feed format and Atom Publishing Protocol. Here's the abstract: Beyond blogging: Atom format and protocol. Like XML-RPC and SOAP before, feeds and publishing protocols were born in the blogopshere and quickly moved beyond blogging. Nowadays, web service providers are using RSS/Atom feeds and REST-based publishing protocols as lightweight alternatives to SOAP. And developers are finding new ways to combine web services from different sites into new applications, known as "mash-ups" in the lingo of Web 2.0. If you'd like to do the same, then attend this talk to learn about the new IETF Atom feed format (RFC-4287) and the soon-to-be-finalized Atom protocol, which together form a strong foundation for REST-based web services development. Check it out!

The following Blogger-generated but independently hosted weblogs have upgraded to Atom 1.0:

• AtomEnabled.org
• St. Cecilia Schola Cantorum
• An Antic Disposition

If your have a blogger-generated but independently hosted weblog, and your host supports PHP, you too can be on this list.

1. Install the script

   Download the script, and upload as atom.php. This file should go in the same directory as your weblog.

2. Promote the new feed

   This can be done in one of two ways:

   1. Redirect

      This is the most complete and comprehensive approach, however not all hosting providers allow users this level of control over the web server. If yours does, try adding the following to a file named .htaccess to the same directory that you placed the atom.php:

      Redirect atom.xml http://your.host.name/path-to-blog/atom.php

      Notes: these instructions are for the Apache Web Server. Instructions for other web servers, including Microsoft's IIS will differ. You will need to tailor your.host.name and path-to-blog.

   2. Advertise

      The other approach is to direct your existing and new subscribers to this new feed. Mention the change on your weblog. Update your auto-discovery and other links. To update your links, go into Settings / Site Feed (pictured below)

      Once you have navigated to that page, change the Site Feed URL to read:

      http://your.host.name/path-to-blog/atom.php

      Notes: You will need to tailor your.host.name and path-to-blog. You may also have other references on your template that need to be updated. Once complete, republish your blog via the Posting / Status tab.

If you have another Blogger produced site that has upgraded to Atom 1.0, feel free to leave a pointer to your site on the Atom wiki. Once your feed has been verified, this weblog post will be updated.

This site's Atom feed has been converted to Atom 1.0. Addionally, the Feed Validator is now issuing deprecation warnings whenever it encounters Atom 0.3 feeds.

An introduction to The Atom Syndication Format has been placed into the Developers > Syndication section of this website.

Thanks to Rakaz for his helpful article on Moving from Atom 0.3 to 1.0 for those looking to implement changes to fully support the 1.0 feed format.

Tim Bray has posted an update on Atom 1.0, with some key links as the IETF works to approve the standard. First, a quick comparison between Atom 1.0 and RSS 2.0, which is useful for implementors, and a number of Atom feed format tests, which the community can make contributions to. At this time, the IETF is expected to accept the draft published at atompub.org as soon as one registered objection is resolved.

Socialtext Atom enabled its Enterprise Social Software to gain offline editing, syndication across private spaces and provide an Atom enabled wiki -- built upon the open source Kwiki.

Mark Pilgrim wrote an excellent howto for making linkblogs in Atom.

Tim Bray is offering to host an Atom Community Meeting June 2nd at Sun’s Silicon-Valley offices. RSVP on the wiki if you can want to help and can attend.

Joe Gregorio implements an Atom enabled wiki

NewsGator Technologies' namesake application has just been launched in a version that's designed for Windows XP Media Center PCs. NewsGator Media Center Edition allows the display and interaction with feeds on your television. With support for rich media and audio, NewsGator MCE shows the importance of Atom's focus on rich data types.

A draft IETF working group charter for Atom has been posted on the wiki. In March, I expect the names of the IETF director(s) and advisors to be filled in, each bullet in the description to be replaced by a paragraph, and dates to be determine in the goals and milestones section.

Pertti Korhonen, Nokia’s new CTO introduced PhotoBlog for Series 60 in his keynote at ETech in San Diego. This application proof-of-concept is supporting the Atom API enabling users to post to leading blog platforms. The application was developed by Futurice, who is developing a Photblog platform.
