What is the change? The old feed just listed events as they were approved into the system, which was useful, but not as useful as getting the events that are occurring today. If you subscribe,your RSS reader will get each days events a minute past midnight of each day.
What next? I need to sit down and write up an RSS API for people who want to customize their feed information a bit more (or who want to get a listing of all changes as they go through the system).
I am also playing around with dumping data in iCal format, for example here is an entry for the Seattle International Film Festival:
I'm not setting the mime-type right just yet so I can finish debugging it. One big problem in the system is that for time the field is just a text field, not a date or duration type. This means that setting iCal output correctly for time is a no go right now. The old system was Slash which had horrible support for time series information. The new system is my forked copy of everything, which has a bit better understanding of meta data (plus it is much easier to extend by me).
