Failing requests for SOS 2.0.0: not parsing procedure names correctly #62

Open pesekon2 opened 4 years ago

pesekon2 commented 4 years ago

Not sure this issue should be opened in this istSOS repo, but as this is the one with interface/admin, hopefully it is the right place

When I try to query the istSOS demo service with SOS version 1.0.0, the following query works without a problem:

http://istsos.org/istsos/demo?service=SOS&
    version=1.0.0&
    request=GetObservation&
    offering=temporary&
    observedProperty=urn:ogc:def:parameter:x-istsos:1.0:meteo:air:rainfall&
    responseFormat=text/xml;subtype="om/1.0.0"&
    eventTime=2015-05-28T00:00:00+0200/2015-06-02T00:00:00+0200&
    procedure=BELLINZONA

However, when I try to change the SOS version (1.0.0 to 2.0.0) and the response format (text/xml;subtype="om/1.0.0" to http://www.opengis.net/om/2.0) as in the following query, I always get an error saying Invalid parameter value in 'procedure' parameter: temporary. 

http://istsos.org/istsos/demo?service=SOS&
    version=2.0.0&
    request=GetObservation&
    offering=temporary&
    observedProperty=urn:ogc:def:parameter:x-istsos:1.0:meteo:air:rainfall&
    responseFormat=http://www.opengis.net/om/2.0&
    eventTime=2015-05-28T00:00:00+0200/2015-06-02T00:00:00+0200&
    procedure=BELLINZONA

Seems like the offering attribute is somehow erroneously parsed into the procedure one.

Hi, In sos 2.0 the offering has changed its meaning, so you can skip the parameter or use the same name as the procedure. Look at the interface for available offerings.

Okay, that sounds very much like my fault/missing knowledge about SOS 1.0.0/2.0 differences. Thank you. And sorry.

However, after changing it to the procedure name or skipping the parameter, I always end up in this error message. Is it something on my side, or on the server side?
