I'm creating a phone app that needs to call data (calendar information, etc.) from a constantly changing website. I have control of the website, so generating a datafile on the website to feed to the phone is not a problem.
What I'm really looking for is something that works kind of like RSS, but where I can add more fields. Using the calendar example, I would need "date", "location", "time", etc. Does this exist? Or would I be better off just using a plain old CSV file?
