A couple of minutes ago I performed a massive Google search looking for information about the official sites of various Italian Ferrari clubs. Most of these sites (well, practically all) don't use RSS/Atom feeds, so it's almost impossible to try to aggregate them using their feeds. So I'll have to try another way. The point is that I basically need a common series of APIs to allow site developers to send their material through a common interface. PHP offers an excellent support to SOAP, so I think that this would be one of the feasible options. Using XML and Ajax would be nice too. The problem here lies in the definition of a common API used to send/receive data through the web. What I'm going to do in the next months is basically trying to develop such an API. Wish me good luck!
