Close.  Yes a glue layer between HTML::Template and a database.  I could 
try to use some of these higher layer abstractions (including Rose:DB) 
or use a modern DBI layer with its 
primay_key/primary_key_info/foreign_key_info functions ...

2) Is the proposed driver.  Retrieved from model component or schema.
