I have a bunch of GML datasets which I need to import to Esri featureclasses. I am using the Data Interoperability extension for ArcGIS, which should support this. However when trying to import my features I get the following error:

"Error when writing Schema: A unique destination featuretype name could not be generated for """


Here is a snippet of the code:

- - -" gml:id="zones"> - - - - inspireId UK_zone - - eng - - Teesside Urban Area - - - -

Do you know whether your GML is of Simple Feature profile? If it is not, then I think it ceases to be a simple matter to import. – PolyGeo Mar 5 '12 at 22:31
@PolyGeo Thanks for responding, how can I tell if it is in fact in SF format? Sorry I am quite new to this. Here is a snippet of the code: – Alex Oulton Mar 6 '12 at 9:43
I'll have to leave answering how to recognize GML-SF to someone more OGC literate than me but for an entry point to ArcGIS 10 documentation on its support for GML this may be a useful URL… – PolyGeo Mar 7 '12 at 9:37
@AlexOulton Did you find a solution? I have the same problem. – Matt Oct 23 '12 at 13:32

I had the same error message, but added a pointer to the XSD file that defined my GML schema (e.g. xsi:schemaLocation=" GML.xsd") in the FeatureCollection tag, and of course ensured the XSD file was in the same directory, and all was fine.
