Radar Masukami and I talk shop about the Second Simple Syndication (SSS) protocol. This is a very short version of the RSS protocol. It was needed to cut down the weight of RSS so that the titles, content links, and podcast links could come through. LSL scripts are only capable of reading a little bit of content.
I sent radar a few copies of files that were updated in the transition to PHP 5. The xml objects that PHP used in version 4 had been renamed and work differently. In addition, I had since updated the code to transform RDF and ATOM into SSS.
