I have the Data Interoperability extension installed and can perform a successful 'Quick Export' to GML and then import back again the exported file into ArcMap.
However, I have an externally sourced GML file that simply will not load and returns the error "Error when writing schema: A unique destination feature type name can not be generated for.."
Please provide advice on how I can load up the below. Does it need to be reformated to a later version of GML. If so what would the new format look like applied to the example below?
For some reason the DI is unable to generate unique layers with your GML file. I'd need to take a look at the GML file to understand why. Are you able to pass it on so I can take a look?
I am having the same problem loading an externally sourced gml file using the quick import tool. Also get the error message "Error when writing schema: A unique destination feature type name can not be generated for ". Did you find a solution to this problem?
You can test any GML/XML with the XMLValidator. You can test GML using the schemas that come with Data Interop in: C:\Program Files (x86)\Esri\Data Interoperability (x86)\xml\schemas\schemas.zip\gml
If you want to test the validity of your files please open a support incident and we'll take a look.
