[BioSQL-l] SwissProt DE lines and UniProt XML / TagTree as XML in BioSQL

[Richard Holland]

Nice idea. Currently, BioJava just stores the complete section as a string without parsing it, but it provides a parser module for converting it into useful tag/value format within a user's program (but not to be stored in BioSQL).
