[BioSQL-l] primary_id for bioentry

[Hilmar Lapp]

In real life there are 3 different kinds of identifiers for 
bioentries (take e.g. Bio::Seq): 1) display_id (human 'readable', 
possibly unstable, aliases to display_name in IdentifiableI, e.g. ), 
2) accession (stable, assigned by the authority), 3) primary_id 
(valid only for a certain database implementation, e.g. GI number 
for Genbank entries).

Bioentry only has columns accession and display_id. I can imagine 
many use cases where someone would want to store db-specific 
identifiers like GI numbers. What do people think about introducing 
an additional column for this?

Or am I mistaken regarding the association between columns and the 
different kinds of identifiers?
