What would be the standard way to provide nested subjects through 
portal_metadata?

For instance, there would be main category for subjects and these would 
have several sub-categories.For example:
'Community'
        'Tourism'
        'Government'
        . . .
'Family'
        'Childcare'
        'Education'
        . . .

I'd like to force them to choose from both a major category and a 
sub-category. Could anyone point me to some resources or examples that I 
could follow?

Thanks in advance.
