Hi, I am trying to have a Geoserver display GML its output in the GeodesyML schema, outlined here <https://geoscienceaustralia.github.io/GeodesyML-Github-Pages/> . In particular, I am working with GPS monument meta data. For now I'm trying to just output the siteName in GeodesyML schema when I click GML in the Layers Preview in Geoserver. The relevant XML schema definition file for GeodesyML is called monumentInfo.xsd. Unfortunately, I can't seem to get the mapping correct from my database schema to GeodesyML. In particular I think the problem is in the <targetElement> or <targetAttribute> fields within <FeatureTypeMapping>. I concluded that I should use geo:GeodesyML as the argument to schemaUri because it is the only xsd file with a top level element (type GeodesyMLType).
How can I use the schema outlined in the monumentInfo.xsd schema definition? Specifically here, how can I map site_name in my database schema to siteName in the GeodesyML schema? Any help is sincerely appreciated and I apologize if my lack of familiarity with XML is causing me to ask a silly question. I have done a fair bit of Google research. The tutorial I followed to get this far is here <http://docs.geoserver.org/latest/en/user/data/app-schema/tutorial.html> , with supporting documentation here <http://docs.geoserver.org/stable/en/user/data/app-schema/mapping-file.html> but they are using GeoscienceML, not GeodesyML. -Gavin Medley *The view I am querying, called geoml_monuments contains:* id | station_code | site_name | geolocation | iers_domex | country_name I am pretty sure this is fine. *The monumentsInfo.xsd file:* https://github.com/GeoscienceAustralia/GeodesyML/blob/master/schemas/monumentInfo.xsd <https://github.com/GeoscienceAustralia/GeodesyML/blob/master/schemas/monumentInfo.xsd> *The GeodesyML.xsd file:* https://github.com/GeoscienceAustralia/GeodesyML/blob/master/schemas/geodesyML.xsd <https://github.com/GeoscienceAustralia/GeodesyML/blob/master/schemas/geodesyML.xsd> *My mapping file:* <?xml version="1.0" encoding="UTF-8"?> <as:AppSchemaDataAccess xmlns:as="http://www.geotools.org/app-schema";
