1. The DIP: it is not possible to view the information/attributes not contained in the GML-file in QGIS. The end-user must open the presentation tool for databases and search for the additional data here, e.g. additional information about a place, building, etc., linked to the geo-data.
2. A collection of relevant files, e.g. the GML files (incl. attributes), additional attribute files and a map. The Archive can deliver the desired additional attributes from the AIP as a csv-file and the end-user can then import this attribute table into QGIS.
3. A shape-file with the geo-data shown on a map: the end-user receives a cvs-file with additional attribute data from the AIP and works with it in his/her own GIS-system.
4. A picture file with the geo-data shown on a map: The Archive producing the picture file with geo-data on a map (print map from QGIS) can add attribute information to the map. However only a little information can be shown on a map or else it will not be very readable.
