Schema Definition with Shape

Hey there,

with Feature Writer I try to adopt a schema from a bunch of different shape files.

I tried the same workflow with a ESRI Geodatabase before and it worked. So I published the Shape Files as Workspace Resources and commit them within the Dynamic Schema Definition.

Which works fine with the Geodatabase, failed (a bit) with the shape files.

In fact the transformed shape files are using the schema, but some of the ESRI data types were changed, namly for example the "Short Integer" changed to "Long Integer" (and also the Precision value changed).

 

Does someone knows why this could happen?

 

Thanks and best regards,

André

Shapefile uses the old dBase IV database files for attribute storage, so it has the constraints, in terms of data types, attribute names and so on, that dBase IV had. When the Geodatabase was introduced ESRI had more or less free hand to develop it, so it has different (less constricting) limitations. FME normally handles this and maps data types to the nearest equivalent.

FME rocks! \m/
