Considering the potential purpose of this app, I think it'd be best to
store it in parts to facilitate lookups by the different classifiers. Also the
strings might change - the government revises them every 5 years or so, I
believe.

classifiers set by the gov that are 4 or fewer levels deep: division,
sub-division, class & group. Most of the time, the objects we're tracking won't
have an advertised code, so the data entry person will need to drill down into
the classifications to hone in on the most appropriate code. I'm thinking 4
sequential select lists for UI. (Let me know if you've a better idea. :-) What
about model-wise? I'm not keen on the idea of creating 3 has_many
relationships, resulting in 4 look-up queries, but I also think a nested set
may be overkill because this isn't n-levels deep, it's always 4 or less. How
should it be designed so that it'll be easy to reference and easy to disp
lay the full compound code string? Please and thank you! -- Tim McEwan Sent
