GeoRSS stands for Geographically Encoded Objects (and we all know what RSS stands for). It could become the standard format for describing routes, trips, and so on.

Here is an example using Google maps. In this example, I created a track and transfered it as a KML file and then referenced it in a HTML page that creates a Google map and initialize it using this KML file.
