Atom 0.3 to RSS 1.0

My blogs are hosted on Blogger. Because Blogger only supports Atom, syndication applications that only read RSS can't subscribe to my blogs. Today I found a useful web service that helped me to create an RSS 1.0 feed from an existing Atom 0.3 feed.

http://cavedoni.com/2004/02/rss1.py

How does it work? The service reads an atom feed and transforms the feed into a live RSS using XSLT. For example, I take my atom feed (http://harry.hchen1.com/cat_semweb/atom.xml), and feed it to the service. I then get back http://cavedoni.com/2004/02/rss1?uri=http://harry.hchen1.com/cat_semweb/atom.xml.

To make the URL look pretty, I added a URL rewrite rule on my server.

RewriteEngine on
RewriteRule ^semweb\.rss$ http://cavedoni.com/2004/02/rss1?uri=http://harry.hchen1.com/cat_semweb/atom.xml [P]

Now, you can subscribe to the RSS 1.0 feed via http://harry.hchen1.com/cat_semweb/semweb.rss
