Hi Ben and Gavin,
The XMl encoder was relaxed to support this use cases:
https://github.com/geoserver/geoserver/commit/6d110b2222bf03db683f8a5c59c566bb75d4d1db
So not sure why it is not working, Galvin can you share with us the XML element
that is including the GnssReceiver element and the related mappings ?
What output do you get with your current mappings, can you past an example ?
Could you also try your WFS request with GeoJSON format ? GeoJson complex
encoder doesn't care about GML stripping rule, if the returned GeoJSON
contains the data you are expecting to see your mappings are ok. Please note
that complex GeoJSON encoder is available only in recent version of GeoServer.
That say, Ben is correct this violate the GML "stripping" and the XML schema
should be fixed.
Regards,
Nuno Oliveira

Gavin,
I do not think that this is a supported mapping pattern. As you note, this violates the
GML object/property "striping" rule. The only reason you see anything at all is
I think because of recent changes to make the encoder more permissive. The problem is
that the dateInserted property falls outside the GnssReceiver object and there is no way
(that I know) in app-schema to express its cardinality or associate it with the
GnssReceiver; this would have to work both for generating output and for converting
filter queries to SQL. Someone else may have a workaround.
I do not think you can express this attribute in UML either. You can think of
gnssReceiver as the UML line representing the relationship between another
class and the GnssReceiver class. In UML, classes have attributes, but as far
as I know, relationships do not.
I think this is a problem with the GeodesyML object model.
Kind regards,
Ben.

Hi,
I understand that App Schema enforces GML striping, i.e. “complex types are
never the direct property of another complex type; they are always
contained in a property type to ensure that their type is encoded in a
surrounding element.” However, in GeodesyML, there are complex types (
geo:GnssReceiver) and simple types (geo:dateInserted) *both* nested inside
a geo:gnssReceiver property element like so.
<geo:gnssReceiver>
<geo:GnssReceiver gml:id="GnssReceiver.87bff11d-a3bc-4e84-b7bc-5175f824f0f5">
<geo:notes>Receiver 1</geo:notes>

</geo:GnssReceiver>
<geo:dateInserted>1996-01-01T00:00:00.000Z</geo:dateInserted>
</geo:gnssReceiver>
I have a feature chained element such that I map geo:GnssReceiver type into
the geo:gnssReceiver property but I cannot figure out how to get
geo:dateInserted to appear in each (of *many*) geo:gnssReceiver elements. I
tried referencing the XPath and simply adding the AttributeMapping after my
GnssReceiver feature chain element (as below) but dateInserted only appears
on *one* instance of gnssReceiver.
...
<AttributeMapping>
<targetAttribute>geo:gnssReceiver</targetAttribute>
<sourceExpression>
<OCQL>fourid</OCQL>
<linkElement>geo:GnssReceiver</linkElement>
<linkField>FEATURE_LINK[1]</linkField>
</sourceExpression>
<isMultiple>true</isMultiple>
<encodeIfEmpty>false</encodeIfEmpty>
</AttributeMapping>
<AttributeMapping>
<targetAttribute>geo:gnssReceiver/geo:dateInserted</targetAttribute>
<sourceExpression>
<OCQL></OCQL>
</sourceExpression>
<encodeIfEmpty>true</encodeIfEmpty>
<isMultiple>true</isMultiple>
</AttributeMapping>
...
Does anyone have a suggestion on how to achieve this or am I missing
something obvious?
Regards,
Gavin
