Yes indeed, for n-n associations you need to use "<=>".

It is actually - both the mapping for term and for seqfeature have the mapping of primary_tag to type_term_id. What error are you getting?
And shouldn't Bio::SeqFeatureI.primary_tag have a double colon instead of the dot? (Also, BTW, you should be able to say "qv.tagname" instead of "Bio::Annotation::SimpleValue::tagname", just as you do for the value column - have you tried that and found it not to work? Either way, what you have for that part looks correct.)
