Hi Martina,

In fact you can, as rank is the field that allows this to happen.  In 
Biojava, currently it's just a linearily incremented number such that 
you can have the same type and source IDs for a given bioentry.

For example, adding a Genbank entry with 10 CDS features for 1 bioentry 
will give you identical keys for bioentry_id, type_term_id and 
source_term_id, but will have a rank of 1 - 10 for each.
