[georss] "When" information in georss

[Andrew Turner]

Hi Charles & Brian - did you ever resolve this question?

I'm curious in particular in light of how best to support responses
from OpenSearch Geo and Time queries

OpenSearch Time makes it easy to request a feed with a begin/end time
points or periods - and then would be nice to support the response in
the RSS/Atom (which with pubdate et al. only nominally support "end
dates" (last updated))

http://www.opensearch.org/Specifications/OpenSearch/Extensions/Time/1.0/Draft_1

By having a time period for items as well as the overall feed would
let consumers/aggregators understand the time period that the feed is
valid for.

thanks,
Andrew
