: in an XML based SOS implementation the filter context can be defined via XPath expressions – see Table 48 in Subclause 13.1.
11.2.1.2 Response
The SOS
GetResultTemplateResponse
data type derives from the SWES
ExtensibleResponse
data type defined in OGC 09-001 and inherits its properties.
Table 41: Properties of GetResultTemplateResponse data type Name
Definition Data type and values
Multiplicity and use
resultStructure The structure of the results which
may be requested in subsequent GetResult calls.
AbstractDataComponent see [OGC 08-094]
One mandatory
resultEncoding The encoding of the results which
may be requested in subsequent GetResult calls.
AbstractEncoding see [OGC 08-094]
One mandatory
Note: different to the result insertion extension, in the result retrieval extension the intention is not to construct complete observations with the result values returned via the
GetResultResponse . Consequently, there is no
requirement on SOS services to include components in the sos:GetResultResponsesos:resultStructure
to provide the phenomenon or result time of observations in. Such components may of course be part of an observation result. As such, SWE Common defined observation
results can easily be retrieved via the GetResultTemplateGetResult operations.
