Extend temporal filtering for further time fields, e.g. valid time

[CarstenHollmann]

Currently the API only supports the temporal filtering for phenomenonTime.
A solution might be to add a referenceValue to the timespan query parameter, similar to the OGC SOS 2.0 KVP definition:

?timespan=validTime,2016-07-13T10:00:00Z/2016-07-13T15:00:00Z

Would prefer another request parameter timefilter which is set to phenomenon by default. Filtering could then performed by setting timefilter=valid ...

when having interval times (see #157) we may combine filters like this

• timspan=PT24H/2016-07-13T15:00:00Z&timefilter=valid:overlap
• timspan=2016-07-13T10:00:00Z/2016-07-13T15:00:00Z&timefilter=phenomenon:within

timefilter=phenomenon:within would be the default and could be ommitted to stay backwards compatible.

Thoughts?

What about validTime=overlaps,...?

Is this feature available now? I am looking for same requirement to filter observation within phenomenonStartTime and phenomenonEndTime for given datetime value in filter.

@sudhamani1983 unfortunately not. The only way to filter temporally is via timespan parameter which checks if phenomenonTimeStart and phenomenonTimeEnd lay within the given filter value.
