[georss] Multiple GeoRSS representations in one feed?

[Josh@oklieb]

Jason,

"GeoRSS Simple" does support lines and polygons, so you don't need to  
go to GeoRSS GML just for that reason. Are you saying that clients  
only support points? Then the best course now would be two feeds.  
Providing multiple geometries as well as the policies and  
relationship tags that indicate when to use which one and why, is not  
yet (or perhaps ever) supported in GeoRSS due to its potential for  
complexity.

One approach which some are taking is to use a simple representation,  
such as a point, in GeoRSS / Atom but provide a link to a more  
complex representation, such as a full GML feature. This is something  
of the approach which might be taken with GeoRSS output from WFS.

Cheers,

Josh
