BioSQL
BioSQL is a generic unifying schema for storing sequences from different sources, for instance Genbank or Swissprot. BioSQL is meant to be a common data storage layer supported by all the different Bio* projects, Bioperl, Biojava, Biopython, and Bioruby. Entries stored through an application written in, say, Bioperl could be retrieved by another written in Biojava.
