Features read from an INTERLIS file consist of a series of attribute values. The attribute values may have no geometry. The attribute names are as defined in the INTERLIS model.

The feature type of each INTERLIS feature is the qualified INTERLIS name (for INTERLIS 2, the qualified name of the class; for INTERLIS 1, the qualified name of the table). The mapping of the inheritance hierarchy is done with a super or sub-type strategy.

ili2fme can read and write INTERLIS 1 and 2. However, in most cases you will need an FME script or FME Workbench to write INTERLIS.
