ensembl is also strictly targetted at "storing features on genome
sequence" whereas BioSQL has a broader "storing biological stuff" target.
Ensembl has been in fact drifting away from Bioperl towards just
supporting an extremely clean Perl and Java API on-top of its
highly-relational focused schema. The bioperl compatibility is now really
around the edges. I may, over the same, build a explicit standalone bridge
between Ensembl and Bioperl which would provide all the usual Bioperl
interfaces from this pretty vanilla schema.
Storing Just Genomes --- choose between Chado and Ensembl, with
undoubtly Ensembl having the current most mature tool sets (including
loaders now from particular flavours of GenBank/EMBL format)
Storing "any" sequence --- BioSQL or roll your own.
