Re: meaning of primaryIdentifier and secondaryidentifier
We populate primaryIdentifier with the main id for a gene but as there
are often many different identifier schemes there is the option to
use secondaryIdentifier as well. There is also a separate symbol field.
In Dropsophila genes have two identifiers from FlyBase, an FBgn number
and CG number, for example 'eve' (the symbol) has primaryIdenifier
FBgn0000606 and secondaryIdentifier CG2328.
As a general rule the primaryIdentifier should always be populated.
