[Geoserver-users] gml temporal support for WFS filter

Any feedback on how or if a filter
can leverage gml temporal types
for WFS requests.

Something like.....

(<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc&quot;
xmlns:gml="http://www.opengis.net/gml&quot;&gt;
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>obsTime</ogc:PropertyName>
<gml:TimeInstant>
<gml:timePosition>2008-05-28T16:44:00</gml:timePostion>
</gml:TimeInstant>
</ogc:PropertyIsEqualTo>
</ogc:Filter>)

----------------------------

Or any of the other types defined in gml
temporal.xsd

Well... GeoServer does not do really any temporal stuff. It would be pretty straight forward to add it to the gml parser, the problem however is that our underlying datastore drivers do not really support time natively. But if your underlying dataset was a database with a date column then it could be mapped over. Feel free to create a task in the bug tracker to support some of the temporal elements .
