The StorageName property needs to refer to the name of a primary data source (a file or database).

It can be configured to a domain-unit, a data-item or container, based on the storagemanager.

Use placeholders in path names, like %SourceDataDir%, to make the configurations easily transferable to other locations/machines, see folders-and-placeholders.

For some StorageManagers, the file extension indicates which StorageManager will be used (.dbf, .shp, .tif). This can be overruled with the storagetype property.
