Hi, first of all, thanks for you hints - they pushed me in the right direction so I can say now that I have been quite successful parsing data sets with complex properties.
In our application we're using a custom API to parse the application schema and create FeatureTypes that represent the definition in the schema (as good as we can) including complex property types and XML attributes. For all concrete feature and property types that are referenced in the schema a binding is created in the configuration, which creates features/complex-attributes quite similar to how it is done in GML2ParsingUtils. Because of our custom API for the schemas this solution can't be integrated directly back into Geotools, but I think there could be done something similar. In any case I hope our results may be useful to someone who also wants to parse features with complex properties. You can find the complete source code online (http://community.esdi-humboldt.eu/repositories/show/hale), for the classes that are relevant to the GML parsing look here: http://community.esdi-humboldt.eu/repositories/browse/hale/eu.esdihumboldt.hale.gmlparser/src/eu/esdihumboldt/hale/gmlparser (most interesting might be the HaleSchemaConfiguration class and its dependencies) Cheers, Simon Am 14.09.2010 13:05, schrieb Jody Garnett: > The parser pays attention to the schema referenced by your GML file; for > anything that it cannot find it will treat it as a hashmap.
