[georss] Time and Space

[Knoth, Brian D.]

Hi,

I'm new to this mailing list, yet have been advocate of RSS and geoRSS
on some internal projects for a while. I do have a few concerns with
regard to real practical acceptance of geoRSS, yet, I understand the
need to try and balance simplicity and expressiveness. As such, we are
attempting to utilize GML geoRSS, however, we have needed to extend the
GML geoRSS with the ability identify time as well as space. 

I wanted to just send out our approach to doing this to get comments
from anyone else who might be interested in this on the mailing list.
Simply put, we have added a GML TimePeriod to each of the geoRSS nodes
along with the spatial representation. Here is an example:

<georss:where>
	<gml:TimePeriod>
   		<gml:begin>2006-06-17T09:55:00Z</gml:begin>
		<gml:end>2006-06-17T10:30:00Z</gml:end>
	</gml:TimePeriod>
	<gml:Point>
		<gml:pos>37.65356495497155 -114.5048399056895</gml:pos>
	</gml:Point>
</georss:where>

All comments would be appreciated.

Regards,
brian
