This is a tough question - I suspect it will be difficult no matter
how you proceed. The API objects don't map 100% directly to database
objects and may not have complete coverage - but using the database
directly will require one to learn a lot of Galaxy's data model I
suspect.

A middle ground - would be to just use the Galaxy code and ORM layer
without running a Galaxy server (see scripts/db_shell.py for
instance).

My gut tells me it is probably be easiest (least difficult anyway) to
target the database directly - but this could be wrong.
