Google Maps has announced that it is now supporting GeoRSS as a data driven geographic content integration method within Google Maps API projects.
From the Google Maps API Blog:
We’ve built support for the Simple, GML, and W3C Geo encodings of GeoRSS — all you have to do is enter the full URL of a GeoRSS file into the Maps query box to load the file. For example, take a look at SlashGeo’s GeoRSS on Google Maps.
Most importantly, we’ve extended support for displaying geographic data — both KML and GeoRSS — into the Google Maps API. Now in addition to programatically adding content to a Maps API site, you can create your content as KML or GeoRSS and load it into the Map with a simple function call. This means that the more than 1 million KML files that are available from all over the web can easily be mashed up with the map on your site.
