Hi JcA,
now I see the issue: theAirspaceVolume is a single-value property, you
should do the feature chaining on the geometryComponent property, which is
multi-valued.
Try this mapping:
<FeatureTypeMapping>
<sourceDataStore>dataStore</sourceDataStore>
<sourceType>airspace</sourceType>
<targetElement>aixm:Airspace</targetElement>
<attributeMappings>
<AttributeMapping>
<targetAttribute>aixm:timeSlice/aixm:AirspaceTimeSlice/aixm:geometryComponent</targetAttribute>
<sourceExpression>
<OCQL>key_aip</OCQL>
<linkElement>aixm:AirspaceGeometryComponent</linkElement>
<linkField>FEATURE_LINK[1]</linkField>
</sourceExpression>
<isMultiple>true</isMultiple>
</AttributeMapping>
...
</attributeMappings>
</FeatureTypeMapping>
<FeatureTypeMapping>
<sourceDataStore>dataStore</sourceDataStore>
<sourceType>airspace_volume</sourceType>
<targetElement>aixm:AirspaceGeometryComponent</targetElement>
<attributeMappings>
<AttributeMapping>
<targetAttribute>FEATURE_LINK[1]</targetAttribute>
<sourceExpression>
<OCQL>key_aip_parent</OCQL>
</sourceExpression>
</AttributeMapping>
<AttributeMapping>
<targetAttribute>aixm:theAirspaceVolume/aixm:AirspaceVolume</targetAttribute>
<ClientProperty>
<name>gml:id</name>
<value>strConcat('AV.', id)</value>
</ClientProperty>
</AttributeMapping>
<AttributeMapping>
<targetAttribute>aixm:theAirspaceVolume/aixm:AirspaceVolume/aixm:upperLimit
</targetAttribute>
<sourceExpression>
<OCQL>upper_value</OCQL>
</sourceExpression>
<isMultiple>true</isMultiple>
</AttributeMapping>
...
</attributeMappings>
</FeatureTypeMapping>
App-schema should correctly encode multiple aixm:geometryComponent
elements, each with a nested aixm:AirspaceVolume element.
Please, let us know how it goes.
