Brent Simmons describes the model he uses for consuming RSS and Atom feeds in Net News Wire.
His internal data format abstracts away from RSS and Atom so that when he displays a feed, he’s only manipulating Cocoa objects.
He says, this is ‘beginning programmer stuff,’ but it’s a powerful technique.
At my old, defunct, company, 2Roam, we never went from HTML to WML directly. We took a cleaned up XHTML version of the page we wanted to display and converted to our own RML markup that the server cached, and from there we’d generate WML optimized for the device, carrier and gateway.
If you click on the 2Roam links in that article, you go to Air2Web, who bought our technology after 2Roam went the way of most startups.
