What Ralph posits is indeed an important question. However, it is not necessary to answer it fully before the database is set up. It would be quite easy to start with the traditional, art history classifications and then later add extra criteria/classes. The database system doesn't care if someone wants to search for all 'Corinthian' helmets or for all 'RAT I-A' helmets.
