Hi Matt,

I think the reason we don't see this stuff in GeoRSS is that GeoRSS is assumed to describe data/documents that are downstream and where spatial information and geometry has already been computed. Maybe there should be a SatlelliteRSS (or whatever :) ) as a set of custom extensions to RSS similar to what GeoRSS does in its own right. 

Really good topic to discuss in general though.

My 2 cents,

When returning spatial information for these granules, according to the new spec we would need to calculate the MBR for the orbit track.  Difficulties of that aside, I don't see any handling of orbit information in either of the GeoRSS specifications.  Is this something you have discussed before?  Is there another specification that we may look to that handles orbit metadata, or are we on our own to specify custom tags if we want to return that information?
