Jody, I have run into a problem at the last step of getting GeoServer to encode a complex feature WFS response. I hope you can help by suggesting a way forward.
GeoServer GML3OutputFormat uses org.geotools.feature.FeatureCollection.getSchema() to get the FeatureType that is to be returned (the content model), and uses it to find the name of the WFS feature type, to locate the FeatureTypeInfo in the catalog. GML3OutputFormat appears to make the unwarranted assumption that the WFS feature type name is the same as the XML schema type name. In general, this is not the case. For example, in GeoSciML we have a WFS feature type gsml:MappedFeature which has XML schema type gsml:MappedFeatureType. As Simon Cox kindly explained to me yesterday: (1) The XML schema complex type definition provides the content model for an XML schema element declaration. [This is the type returned by getSchema().] (2) The XML element declaration defines the WFS feature type and name. [This is the feature attribute descriptor name.] Looking at the old GeoServer 1.6 community-schemas fork, I see that a concrete feature collection implementation was used that allowed access to the underlying feature attribute descriptor, and hence the WFS feature type name. A possible solution is to add a getName() method to FeatureCollection to allow the discovery of the WFS feature type name used to create the FeatureCollection. This will require modification of numerous implementations. To avoid changing many implementations, I could instead add a new interface (e.g. NamedFeatureCollection) extending FeatureCollection, and use instanceof in GML3OutputFormat. Which would you prefer?
