RSS2Timeline

This service provides an RSS to Timeline translator.
Using it, any RSS or Atom feed will be translated to JSON/Timeline format so that you can load it directly into your Timeline:

  Timeline.loadJSON("http://apassant.net/home/2006/07/rss2timeline/translate?uri=http://mywebsite/feed.rss", 
    function(xml, url) {
      eventSource.loadJSON(xml, url);
    }
  );
Just use the following URL with your feed as uri parameter, and you'll get the feed in JSON/Timeline format:
http://apassant.net/home/2006/07/rss2timeline/translate?uri=

You can check there what your feed will look like:
