The requirements of my client have been the import of the same category in each of the languages featured: in short, multiple iterations of categories that are no in the same branch. I can not determine in nph-import.cgi --help if it is possible to addpend multiple categories to the --rdf-category switch.

Would it perhaps be something like

$ perl nph-import.cgi [--source] [--destination] --rdf-category="Top/Home/Cooking;Top/Home/Family"

Thanks again for all the help so far.
