Dear Amar Ghandi, Group Program Manager of the Windows RSS team,
You guys actually invented the RSS parser and feed API? Your patent claim is baffling:

“A content syndication platform, such as a web content syndication platform, manages, organizes and makes available for consumption content that is acquired from the Internet. In at least some embodiments, the platform can acquire and organize web content, and make such content available for consumption by many different types of applications. These applications may or may not necessarily understand the particular syndication format. An application program interface (API) exposes an object model which allows applications and users to easily accomplish many different tasks such as creating, reading, updating, deleting feeds and the like.”

That describes tons of applications both corporate and open source. Any programmatic API like ROME comes to mind. Did you create the RSS Platform in Windows Vista before all of them? Please do tell, I’m all ears.
(More objections by Dave Johnson here. CNET coverage here.)

Just announced:

A new release of the RSS and Atom Utilities (ROME) project 0.9 (beta) is now available on the project’s Java.net website. This new release includes fixes to Atom relative URI resolution, easier parsing for RSS feeds that use , better support for mapping of RSS to and from Atom and numerous small fixes.

Here are some quick links to the relevant release docs and files.
• Release page
• Change list
• Javadocs

O’Reilly (the company, not Tim) asked me to put together a Short Cut on building RSS 2.0 feeds. The intended audience is people who would like a nice starter guide to building feeds and best practices, but don’t want to invest in a printed book just yet.

How to Build an RSS 2.0 Feed

Something unique to this piece is the stated intent to follow the RSS Advisory Board’s profile recommendations as much as possible. (AFAIK this is the first commercially-published work to do so.)

I’d like to repeat my hearty thanks to James Snell and Simon St. Laurent for their contributions.

The title page doesn’t give much of a sense what is inside, so I thought it might be helpful to give a full table of contents. The “Anatomy” chapter in particular goes through every RSS element in detail, giving examples of usage and identifying best practices where applicable.

The feed I use powered by MySyndicaat to look for interesting RSS and Atom stories picked up an unusual hit this morning… a project on ScriptLance.com:

RSS/Atom Writer/Generator

In search of RSS 2.0/Atom writer/generator in the form of PHP class to extract defined specific data fields. The same concept as the RSS feeds (on the fly) like Flicker.com .I.E (http://www.flickr.com/photos/missfit666/)

It should be a simplified, reusable and commented code. It should also include Automatic site URL detection by simply referencing the siteurl , $file = somefile.php. etc..

I’ve seen and written a few manual RSS generators in PHP, but nothing that would approach a library like Java’s ROME. I’ve got to believe there is a robust PHP library out there already. Anyone know of one?

Nathan Freitas has just announced the 1.0 release of ION, a desktop open-source media/podcast player that supports an array of audio/video/image file formats. ION works on *nix, Windows, and Mac platforms.

A video tour of ION and screenshots are available, or you can try ION right now via Java Webstart (~5MB):

From Nathan:

“Written in Java, available for Windows, Mac OS, and Linux/Solaris/*nix, uses ROME and the Modules subproject heavily, and is licensed under the Mozilla Public License.”

“… Learn about our playlist sharing service at http://iondb.com … Drag and drop any posts or media from other feeds or searches into a custom playlist… This is accomplished by ION being not only a parser/consumer of feeds, but also a generator - remixing items from other feeds into a new feed which is published up to our servers as RSS.”
