Thanks to some tweaks suggested by Aaron Swartz, the Pie/Echo/Atom folks are exploring the possibility of formating the syndication format in RDF/XML.
As I’ve said in comments – this is a very good thing. It unifies RSS 1.0 and RSS 2.0 beautifully and justifies having yet another syndication effort. Discussion on this continues at the syndication feed email list.
Good job Aaron, Sam, others in the group.
